What is a home extension Hampstead?
A home extension in Hampstead is one of the most effective ways to create additional living space while protecting the long-term value of a property in one of London’s most desirable residential areas. Whether you own a Victorian terrace near South End Green, an Edwardian family house on a quiet residential street, a period villa close to Hampstead Heath, or a more contemporary property tucked behind the village core, extending well can transform how your home functions day to day. The right scheme can deliver a larger kitchen, open-plan family space, utility room, guest suite, home office, improved circulation, and a much stronger connection to the garden.
Hampstead is, however, a location where home extension design requires more care than in many other parts of London. Properties often sit within conservation areas, many streets contain listed or heritage-sensitive buildings, and planning expectations are typically higher where local character, rooflines, materials, mature trees, privacy, and streetscape quality are concerned. In practical terms, that means a successful home extension in Hampstead must balance ambition with restraint. It needs to be architecturally intelligent, planning-aware, structurally practical, and beautifully detailed.
From an architectural perspective, the best extensions do far more than add square metres. They improve natural light, reshape awkward layouts, resolve level changes, introduce better storage, and create spaces that feel calm, generous, and tailored to modern family life. A side return extension can turn a narrow dark kitchen into a bright sociable room. A rear extension can open a house to the garden and provide room for dining, entertaining, and everyday family use. A loft extension can create a principal suite or children’s bedrooms without sacrificing garden space. A basement extension, where suitable, can provide substantial additional accommodation in high-value areas where expanding upward or outward is constrained.
For homeowners searching for guidance on a home extension in Hampstead, the key questions are usually the same. What type of extension is best for the property? Will planning permission be needed? How much will it cost in NW3? How long will the process take? Which design decisions add value, and which create risk? This guide answers those questions in detail, with a focus on the realities of extending homes in Hampstead. It covers extension types, planning considerations, building regulations, realistic cost ranges, programme expectations, and the most common mistakes to avoid.
Because Hampstead homes vary so widely, there is no one-size-fits-all answer. A compact rear infill project on a terraced house will have a very different design and budget profile from a full-width rear extension with structural reconfiguration, or a basement and ground floor remodel in a detached period property. Site access, party wall matters, tree protection, drainage, conservation constraints, and the quality of existing construction all affect scope and cost. This is why early feasibility, measured surveys, and a carefully coordinated architectural strategy are so important.
If your goal is to gain more space without leaving the area, a well-designed extension is often a better solution than moving. It allows you to remain close to schools, parks, transport, and the neighbourhood character that makes Hampstead so attractive, while creating a home better suited to your family’s future. The most successful projects begin with a clear brief, realistic budgeting, and a design team that understands both the architectural opportunities and the planning sensitivities of Hampstead.
Types of home extension Hampstead
Understanding the different types of home extension hampstead available is essential for making the right choice for your property, budget, and requirements. Each type has distinct advantages, cost implications, and suitability for different property types.
Rear Extension
A rear extension is one of the most popular choices for a home extension in Hampstead because it can dramatically improve ground floor living without fundamentally altering the street-facing appearance of the house. It is particularly effective for Victorian and Edwardian homes with underused rear projections, fragmented kitchens, and disconnected dining spaces. A rear extension can create a larger kitchen-diner, family room, utility area, pantry, and better visual connection to the garden. When designed carefully, it also improves daylight by introducing rooflights, slim framed glazing, and wider openings between old and new spaces. In value terms, this type of extension often aligns well with buyer expectations in Hampstead, where generous kitchen and entertaining spaces are highly desirable.
The main disadvantages are the impact on garden depth, the potential need for planning permission in conservation-sensitive locations, and the structural complexity of opening up the original rear wall. Drainage runs, manholes, level changes, and neighbouring windows can all influence the layout. If the extension is too deep or poorly proportioned, it can darken the existing house and feel disconnected from the original architecture. On tighter sites, construction access may also be difficult, increasing labour costs and programme length. In Hampstead, rear extensions often require particularly careful material selection and massing control to satisfy planners and preserve the character of period homes.
Side Return Extension
A side return extension is ideal for many terraced and semi-detached properties in Hampstead where a narrow alleyway or side passage sits unused beside the kitchen. By infilling this strip, the footprint increase may appear modest on paper, but the effect on the internal layout can be transformational. It allows a cramped rear room arrangement to become a broad, open, practical kitchen-living space with improved circulation and more usable wall lengths for cabinetry. This type of extension often preserves more garden than a full rear projection and can work extremely well with glazed roof sections that bring daylight deep into the plan. For homeowners seeking efficient added space with strong lifestyle benefits, the side return is often one of the best-value options.
The challenge with side return extensions is that they require highly disciplined design to avoid creating awkward, tunnel-like spaces or overheating beneath extensive glazing. Existing drainage and inspection chambers are frequently located in the side passage, which can add cost. Party wall matters are common because the work is usually close to the neighbouring boundary. The roof design, junctions with the existing building, and internal structural strategy need careful coordination. In Hampstead, planners may also be attentive to the visual impact of rooflights, parapets, boundary conditions, and the relationship with adjoining historic fabric.
Wraparound Extension
A wraparound extension combines a side return and rear extension to create a substantial increase in ground floor accommodation. This can be especially effective in Hampstead family homes where the aim is to establish a large kitchen, dining, and living zone, along with utility, cloakroom, boot room, or study areas. The wraparound format offers excellent freedom for re-planning and can resolve awkward existing layouts where multiple small rooms no longer suit modern living. It is often the best way to create a single coherent family hub while retaining flexibility for entertaining and day-to-day use. If designed with strong roof geometry and carefully positioned glazing, it can produce bright, elegant spaces that feel integrated with the original house.
Because it is larger and more complex than a simple infill, a wraparound extension usually brings higher planning risk, greater structural intervention, and a larger budget. It may remove a significant portion of garden space and can affect neighbouring outlook more than smaller extension types. Construction is more disruptive because substantial demolition, steelwork, and internal reconfiguration are common. In Hampstead, wraparound designs need particular sensitivity to scale, materials, and the hierarchy of old and new elements so that the extension complements rather than overwhelms the host building.
Loft Extension
A loft extension is a strong option for homeowners who need extra bedrooms, a principal suite, or a home office but want to preserve garden space. In Hampstead, where land values are high, extending upward can be a practical and financially efficient way to unlock hidden volume within the roof. Dormer loft conversions, mansard forms where appropriate, and carefully integrated roof extensions can create highly desirable accommodation with excellent views and privacy. They are particularly useful for growing families who need another floor of habitable space without major changes to the ground floor footprint.
Not every Hampstead property is suitable for a loft extension. Roof form, ridge height, conservation area restrictions, and neighbouring context all affect feasibility. Stair design is critical and can impact the floor below more than clients expect. Structural upgrades, fire safety measures, acoustic separation, and insulation standards can be extensive. In heritage-sensitive settings, visible dormers or roof alterations may face planning resistance. Loft projects can also expose hidden issues such as undersized rafters, chimney constraints, and irregular existing construction.
Basement Extension
A basement extension can provide major additional accommodation where outward and upward expansion is constrained. In Hampstead, this may include cinema rooms, gyms, guest suites, playrooms, wine storage, utility zones, plant rooms, or even expansive family spaces with lightwells and landscaped courtyards. For high-value homes, a well-designed basement can significantly enhance functionality while preserving the garden and the external appearance of the house. It can also allow the ground floor to remain more elegant and uncluttered by moving service functions below.
Basement extensions are among the most complex and expensive forms of residential construction in London. They require detailed structural and geotechnical design, waterproofing expertise, excavation logistics, neighbour protection, and often extensive planning scrutiny. In Hampstead, issues such as topography, mature trees, groundwater, local planning policy, and construction impact can be especially significant. Programmes are longer, risks are higher, and temporary works can be substantial. A basement should only be pursued after rigorous feasibility and cost planning.
Planning Permission in London
Planning for a home extension in Hampstead requires a local, context-led approach. While some smaller projects elsewhere in London may fall within permitted development rights, homeowners in Hampstead should never assume this applies automatically. Conservation area status, Article 4 directions, listed building designation, previous planning history, and site-specific constraints can all remove or limit permitted development rights. Even where rights technically exist, a Certificate of Lawfulness is often advisable to confirm that the proposed works are lawful before construction begins.
Hampstead contains a rich variety of architectural character, from Georgian and Victorian buildings to Arts and Crafts influences, Edwardian houses, mansion blocks, and later infill development. Camden planning officers typically expect proposals to respond carefully to the host building and the wider streetscape. This does not necessarily mean that every extension must imitate the original style. Contemporary additions can be successful, but they must be proportionate, well detailed, and respectful in massing, materials, and visibility. The strongest applications usually demonstrate a clear architectural rationale rather than relying on generic extension templates.
For rear and side extensions, the main planning considerations often include depth, height, roof form, impact on neighbouring amenity, overlooking, overshadowing, and how the proposal reads against the original house. In terraced and semi-detached streets, the relationship to adjoining properties matters greatly. A design that appears acceptable in isolation may still be resisted if it creates an overbearing effect or breaks an established rhythm of built form. Where properties back onto gardens with mature landscaping, tree root protection and biodiversity considerations may also come into play.
If your property is listed, listed building consent may be required in addition to planning permission, and the threshold for acceptable intervention is much higher. Internal alterations affecting historic fabric can be just as significant as external changes. Original staircases, cornicing, fireplaces, joinery, windows, brickwork, roof structures, and plan form may all be relevant. In these cases, the design process should begin with a careful understanding of significance so that new work enhances the building without causing heritage harm.
Basement extensions in Hampstead are particularly sensitive from a planning perspective. Borough policies often require detailed supporting information covering structural methodology, hydrology, drainage, construction management, and impact on neighbouring properties. The slope and geology of parts of Hampstead can intensify scrutiny. Even where a basement seems physically possible, planning policy may limit scale, footprint, or external manifestations such as lightwells and railings.
A robust planning strategy usually starts with a measured survey, photographic analysis, and a feasibility study that tests realistic options against local policy and site conditions. Pre-application advice can be valuable for more complex schemes, especially in conservation areas or where heritage issues are present. Drawings should clearly explain existing and proposed conditions, and supporting documents may include a design and access statement, heritage statement, daylight and sunlight information, tree reports, and structural notes depending on the project. In Hampstead, clarity and design quality matter. A carefully prepared submission often saves time and reduces the risk of revisions later.
Neighbour relations are also an important practical aspect of planning. Even where planning permission is likely, objections can delay or complicate the process. Thoughtful massing, privacy protection, and early communication can make a meaningful difference. Good architects do not simply design for approval; they design for buildability, neighbourly impact, and long-term quality. That is especially important in Hampstead, where planning decisions often reflect both policy and the high expectations associated with the area’s architectural character.
Building Regulations
Building regulations are a separate process from planning permission, and every home extension in Hampstead must comply with them regardless of whether planning consent is required. Building regulations focus on health, safety, energy efficiency, structural performance, drainage, fire protection, ventilation, and accessibility. In practice, this means that even a visually simple extension can involve extensive technical design before construction starts.
Structure is one of the most significant areas. Many extensions require the removal of existing loadbearing walls and the installation of steel beams, padstones, columns, or new foundations. The design must account for soil conditions, proximity to trees, drainage runs, and the interaction between the existing house and the new build. In older Hampstead properties, hidden conditions are common. Existing walls may not be perfectly straight, foundations may be shallow, and previous alterations may not have been documented properly. A thorough structural design process helps reduce surprises on site.
Thermal performance is another major requirement. New walls, roofs, floors, glazing, and doors must meet current standards for insulation and energy efficiency. This often influences build-up thicknesses, floor levels, roof edges, and junction detailing. In period homes, integrating modern insulation while preserving breathability and managing condensation risk can be complex. The technical detailing needs to be carefully coordinated so that the extension is comfortable, efficient, and durable.
Fire safety requirements are especially important where extensions are combined with broader internal alterations or loft conversions. Escape routes, fire doors, smoke detection, protected stair enclosures, and means of egress windows may all be relevant. If the project creates an additional storey or significantly changes the internal arrangement, the fire strategy must be reviewed as a whole rather than room by room. This is one reason why piecemeal design can create problems. A coordinated architectural and building control approach is more effective.
Drainage is often underestimated at the early stages of a Hampstead extension project. Existing foul and surface water runs may sit exactly where new foundations or floor slabs are proposed. Manholes frequently need to be relocated, and if a public sewer is affected, approval from the relevant water authority may be required. Basement and lower ground projects introduce further complexity around waterproofing, sump systems, and external drainage design. Getting this wrong can be costly and disruptive, so drainage should be considered from the outset.
Ventilation and indoor air quality also deserve attention, especially in airtight modern extensions with large areas of glazing. Kitchens, utility rooms, bathrooms, and basements need adequate extract ventilation, while habitable rooms require appropriate background ventilation and purge ventilation. In more advanced projects, mechanical ventilation with heat recovery may be considered to improve comfort and efficiency. Acoustic performance can matter too, particularly in party wall situations or where plant equipment is introduced.
Finally, building regulations compliance depends on documentation quality as much as design intent. Detailed construction drawings, specifications, structural calculations, and coordinated consultant information help ensure that the extension is priced accurately, built correctly, and signed off efficiently. In Hampstead, where projects are often architecturally ambitious and physically constrained, technical design is not an afterthought. It is one of the main factors that determines whether the finished extension feels refined, performs well, and stands the test of time.
home extension Hampstead Costs in London 2025
The cost of a home extension in Hampstead depends on far more than floor area alone. While online calculators often suggest simple square metre rates, real project costs are shaped by design complexity, structural intervention, site access, specification level, planning constraints, and the condition of the existing building. In a premium London location such as Hampstead, labour rates, logistics, and finish expectations are typically above average, so budgeting should be realistic from the start.
A small extension project, such as a modest side return or compact rear infill with limited internal reconfiguration, may begin around £50,000 to £95,000. At this level, the scope usually needs to be tightly controlled. Costs can rise quickly if the project includes extensive glazing, bespoke joinery, underfloor heating, new drainage runs, high-end kitchen works, or significant steelwork. Even relatively small extensions can become technically involved where access is poor or the house has hidden structural issues.
A medium-sized home extension in Hampstead, such as a larger rear extension, wraparound ground floor reconfiguration, or a loft extension with good-quality finishes, often falls in the region of £95,000 to £180,000. This budget range may include more substantial demolition, multiple structural openings, upgraded services, and a higher level of interior integration with the existing house. For many family homes, this is the bracket where the project begins to feel transformative rather than incremental.
Larger projects, including full-width rear extensions with major internal remodelling, complex loft works, or high-specification schemes with bespoke glazing and joinery, commonly start from around £180,000 and can exceed £350,000. Basement extensions or projects involving listed buildings, extensive landscaping, or premium interior packages may go considerably beyond this. In Hampstead, it is not unusual for the fit-out element alone to represent a substantial proportion of the total budget where kitchens, bathrooms, stone surfaces, specialist lighting, and custom cabinetry are central to the design.
Clients should also remember that construction cost is only one part of the overall investment. Professional fees for architecture, structural engineering, planning consultancy where needed, party wall surveying, building control, and specialist reports must be allowed for. There may also be costs for Thames Water approvals, tree surveys, heritage statements, and temporary accommodation if the works are disruptive. VAT can be a major budget factor on most extension projects and should never be overlooked in early planning.
Contingency is essential, especially in older Hampstead properties. Opening up works frequently reveal issues such as damp, decayed timbers, inadequate historic alterations, chimney complications, or drainage conflicts. A sensible contingency can protect the project from stalling if these arise. The exact amount depends on scope and risk, but for refurbishment-heavy extensions it is prudent to allow a meaningful reserve rather than budgeting to the absolute limit.
The best way to control cost is not to design the cheapest possible extension on paper. It is to align scope, planning strategy, technical design, and specification from the beginning. Clear priorities help. If your main objective is to create a better kitchen-family room, budget should be concentrated there rather than spread thinly across too many secondary upgrades. Likewise, early decisions about glazing systems, joinery quality, flooring, heating, and lighting help avoid expensive changes later. In Hampstead, where expectations are high and build conditions can be challenging, disciplined cost planning is one of the strongest predictors of a successful project.
Quick Cost Summary
Timeline: How Long Does It Take?
The timeline for a home extension in Hampstead varies according to scale, planning complexity, and how much of the existing house is being altered alongside the new build. As a broad guide, a straightforward extension may take around six months from initial design to completion, while more complex or heritage-sensitive schemes can take nine to twelve months or longer. The key point is that the visible construction phase is only one part of the process. Design development, planning, technical coordination, and contractor preparation all take time and should not be rushed.
The design stage often takes around four to eight weeks for initial feasibility, concept development, measured survey coordination, and preparation of planning drawings. This stage is crucial because it establishes the brief, tests different extension options, and identifies likely planning or structural issues early. In Hampstead, this period can be especially important where conservation area context, neighbour relationships, or listed building considerations affect the design direction. Spending enough time here usually leads to a stronger, more deliverable scheme.
If planning permission is required, the formal planning stage commonly takes eight to twelve weeks, although this can extend if revisions are requested or if the application is particularly sensitive. Pre-application discussions, if pursued, may add time but can reduce uncertainty. Homeowners should also factor in the possibility of additional consultant input during this stage, such as heritage advice, tree reports, or daylight information. A realistic programme should allow for these possibilities rather than assuming immediate approval.
Once planning is secured, technical design and building regulations information must be prepared. Although this can overlap with procurement, it should not be compressed excessively. Detailed drawings, structural engineering, and specification coordination are what enable accurate pricing and smoother construction. For projects in Hampstead, where build quality and detailing expectations are high, this stage is often where the difference between an average result and an excellent one is made.
The construction period itself can range from around twelve weeks for a small extension to twenty-four or even thirty-two weeks for larger, more complex schemes. Basements, listed building works, and projects with major internal remodelling can take longer. Site access is a major timeline factor in Hampstead. Narrow roads, restricted storage, neighbour proximity, and limited side access can all slow progress. Weather, lead times for glazing or bespoke joinery, and inspection sequencing may also influence the programme.
The finishing stage, including second fix joinery, decoration, flooring, kitchen installation, snagging, and final approvals, often takes two to six weeks depending on specification. This is the phase that clients most remember because visible progress accelerates, but it is also where rushed decisions can undermine the quality of the whole project. Lighting positions, ironmongery, paint finishes, cabinetry details, and final coordination of appliances all matter.
Overall, the most successful Hampstead extension projects are those planned with a realistic timeline from the outset. Trying to force a complex extension through design, planning, and construction too quickly usually creates stress, compromises, and avoidable cost increases. A well-managed programme allows enough time for good decisions, careful approvals, and high-quality execution.

The Design Process
At Hampstead Renovations, we follow a structured design process for every home extension hampstead project. This process has been refined over hundreds of projects across North London and ensures that nothing is overlooked, budgets are managed, and the final result exceeds expectations.
1. Initial Brief & Site Visit
Every project begins with a conversation. We visit your property, listen to your requirements, understand your budget, and assess the feasibility of your ideas. For home extension hampstead, this initial visit is crucial — we need to understand the existing structure, identify constraints, and discuss the range of options available to you. This meeting is free and without obligation.
2. Concept Design
Based on the brief, we develop two or three concept design options. These are presented as floor plans, sections, and 3D visualisations so you can understand how the space will look and feel. We discuss the pros and cons of each option, the cost implications, and any planning considerations. This phase typically takes 2–3 weeks.
3. Developed Design
Once you have chosen a preferred concept, we develop it in detail. This includes finalising the layout, specifying materials and finishes, developing the structural strategy with our engineer, and resolving all the technical details that affect how the space works. We provide a detailed cost estimate at this stage so you can make informed decisions about specification.
4. Planning Application (if required)
If planning permission is needed, we prepare and submit the application, including all supporting documents (design and access statement, heritage impact assessment for listed buildings, structural methodology for basements). We manage the application process, respond to any council queries, and negotiate with planning officers where necessary.
5. Technical Design & Building Regulations
We produce detailed construction drawings and specifications — the documents your contractor will build from. These include architectural plans, sections and elevations, structural engineering drawings, services layouts, and a comprehensive specification of materials and workmanship. We submit for Building Regulations approval and manage the approval process.
6. Tender & Contractor Appointment
We invite three to four vetted contractors to price the project from our detailed drawings and specification. We analyse the tenders, interview the contractors, and recommend the best appointment based on price, programme, experience, and references. We help you negotiate the contract terms and agree a realistic programme.
7. Construction & Contract Administration
During construction, we carry out regular site inspections to ensure the work complies with the design, specification, and Building Regulations. We chair progress meetings, manage variations, certify interim payments, and resolve any issues that arise. Our role is to protect your interests and ensure the project is delivered to the agreed quality, programme, and budget.
8. Completion & Handover
At practical completion, we carry out a thorough snagging inspection and produce a defects list for the contractor to address. We manage the Building Control final inspection, obtain the completion certificate, and compile a comprehensive handover pack including all warranties, certificates, maintenance guides, and as-built drawings.
Common Mistakes to Avoid
Over hundreds of home extension hampstead projects across London, we have seen the same mistakes repeated. Learning from others' errors can save you thousands of pounds and months of frustration.
1. Assuming permitted development applies automatically
Many homeowners begin with the assumption that a rear or side extension can be built without formal planning permission. In Hampstead, this is risky because conservation area controls, listed status, and local planning constraints may remove or limit those rights. Always verify the planning position before committing to design or construction.
2. Underestimating structural complexity
Opening up period homes often involves more than removing a wall and adding glazing. Steelwork, foundation upgrades, drainage diversions, chimney support, and hidden defects can all affect cost and buildability. Early structural input is essential.
3. Focusing on floor area instead of layout quality
A larger extension is not automatically a better extension. Poorly planned space can feel dark, awkward, or disconnected from the rest of the home. The priority should be how the extension improves circulation, light, storage, and everyday living.
4. Setting an unrealistic budget
Hampstead projects often cost more than generic London averages because of access constraints, high finish expectations, and planning sensitivity. Budgets should include professional fees, VAT, contingency, and fit-out costs, not just the shell construction.
5. Ignoring neighbour and party wall issues
Extensions close to boundaries frequently require party wall notices and careful management of neighbour relationships. Delays often occur when these matters are left too late. Addressing them early helps protect programme and goodwill.
6. Overglazing without environmental control
Large rooflights and sliding doors can look impressive, but too much glass without shading, ventilation, and thermal planning can lead to overheating, glare, and poor comfort. Good extension design balances light with performance.
7. Rushing technical design
Insufficient detail before tender or construction often leads to vague pricing, contractor assumptions, and expensive site changes. Detailed drawings and coordinated specifications are vital for quality and cost control.
How to Choose a Contractor
The choice of contractor is one of the most important decisions you will make in any renovation project. A good contractor delivers quality work on time and on budget; a poor one can cause delays, cost overruns, defective work, and enormous stress. Here is how to find and evaluate the right contractor for your project.
What to Look For
- Relevant experience: Ask to see completed projects similar to yours in type, scale, and specification. A contractor who specialises in basement conversions may not be the best choice for a period restoration, and vice versa. Request references from recent clients and, if possible, visit a completed project
- Insurance: Verify public liability insurance (minimum £5 million), employer's liability insurance (a legal requirement if they employ anyone), and professional indemnity insurance if they are providing any design input. Ask to see current certificates, not expired ones
- Trade body membership: Membership of the Federation of Master Builders (FMB), TrustMark, or the National Federation of Builders (NFB) provides some assurance of competence and financial stability. For specialist work, look for relevant accreditations (e.g., PCA for waterproofing, NICEIC for electrical)
- Financial stability: A contractor who goes bust mid-project is every homeowner's nightmare. Check Companies House for financial health, look for a stable trading history, and consider whether the company has sufficient resources to manage your project alongside their other commitments
- Communication style: During the quoting process, assess how responsive, clear, and professional the contractor is. This is a preview of how they will communicate during the project. If they are slow to return calls or vague in their quotes at this stage, it will not improve once they have your money
Red Flags to Avoid
- Quoting without visiting the site or seeing detailed drawings
- Requesting large upfront payments (more than 10–15% of the contract value)
- No written contract or a vague, one-page quotation
- Pressure to commit quickly or "special" discounts that expire
- Unable or unwilling to provide references from recent projects
- No insurance certificates available for inspection
- The quote is significantly lower than all others — this usually means something has been missed, not that they are offering better value
Questions to Ask
- How many similar projects have you completed in the last two years?
- Who will be the site manager/foreman for my project, and how many other projects will they be managing simultaneously?
- What is your proposed programme (start date, key milestones, completion date)?
- How do you handle variations and additional work — what is your day rate for unforeseen items?
- What warranty do you provide on your work?
- Can I speak to three recent clients whose projects are similar to mine?
Case Studies
Our portfolio includes hundreds of home extension hampstead projects across London. Here are three examples that illustrate the range of work we undertake:
Victorian Terrace, Hampstead (NW3)
A comprehensive home extension hampstead project on a four-bedroom Victorian terrace in a conservation area. The project required careful liaison with Camden planning officers to ensure the design respected the architectural character of the street while delivering modern living standards. Completed on time and within the agreed budget, the project added approximately 20% to the property value.
Edwardian Semi, Crouch End (N8)
A family of five commissioned this home extension hampstead project to create additional space and modernise the property while retaining its Edwardian character. Original features including cornicing, ceiling roses, and timber panelling were carefully restored, while new elements were designed in a contemporary style that complements rather than imitates the original architecture.
Period Property, Highgate (N6)
This substantial home extension hampstead project in Highgate Village required Listed Building Consent and close collaboration with the local conservation officer. The design balanced the need for modern comfort and energy efficiency with the preservation requirements of the listed building. Specialist heritage contractors were appointed for sensitive elements including lime plastering, timber window restoration, and stone repairs.
