Whole-property refurbishment in Hampstead Garden Suburb frequently involves conservation-area consent — and listed-building consent where applicable — so London Borough of Barnet assesses external alterations, windows and structural changes alongside Building Regulations, often with party wall agreements on terraced and semi-detached homes.
Hampstead Garden Suburb NW11 sits within the Hampstead Garden Suburb Conservation Area, and Barnet's Local Plan applies, and in the Suburb the Hampstead Garden Suburb Trust adds a second, stricter layer of design control on top of council consent. The Suburb is one of the most tightly controlled areas in London. Our RIBA architects prepare and submit every application to London Borough of Barnet and handle pre-application discussions where a scheme is finely balanced.
Full Refurbishment in Hampstead Garden Suburb must satisfy Building Regulations — covering structural alterations to Part A, fire safety to Part B, thermal upgrades to Part L, and electrical and gas certification. Our in-house engineers manage Building Control from initial notice through to the completion certificate.

Barnet · NW11
Strip it back, reimagine it, rebuild it beautifully. Our full refurbishment service takes a tired or dated London home and transforms every room — reconfiguring layouts, upgrading all services, installing new kitchens and bathrooms and delivering a cohesive interior design that unifies the entire property. One team, one contract, one vision.
Hampstead Garden Suburb NW11 is an Arts & Crafts conservation showpiece governed by the Suburb Trust's Scheme of Management and an Article 4 Direction, so a full refurbishment must satisfy Trust consent alongside the council before any whole-house works begin. Our architectural design and structural engineering teams lead the design so layout, structure and services are resolved together under one fixed-price process.
Refurbishment works fall under Barnet, and where the property is listed or in a conservation area, alterations to protected fabric can require listed building consent. We establish the relevant designations at feasibility and run the planning and conservation consents in parallel with the build.
A full refurbishment touches structure throughout — openings, beams and often a basement or loft — so works to shared structures engage the Party Wall etc. Act 1996, and the programme is sequenced from strip-out through first fix, plaster, second fix and fit-out. See our Hampstead Garden Suburb work or book a consultation.
A full refurbishment goes far deeper than new paint and replacement kitchens. It addresses everything behind the walls — rewiring electrical systems that haven't been updated since the 1960s, replacing lead plumbing with copper and plastic, insulating solid walls that leak heat through every brick, and reconfiguring floor plans designed for a Victorian household with live-in servants, not a contemporary family.
Our approach starts with the layout. Before selecting a single tile or paint colour, our architects redesign the floor plan — opening up cramped ground floors, relocating bathrooms, creating en-suites, adding utility rooms, improving circulation and sight-lines, and ensuring every square metre works harder.
Once the layout is resolved, our interior designers develop a cohesive design language that runs through every room — material palettes, joinery profiles, ironmongery, lighting schemes, tile specifications and colour stories developed as a unified whole. The result is a home that feels intentional throughout.
Every refurbishment is delivered under a single fixed-price contract covering design, structural alterations, full M&E, kitchen, bathrooms, flooring, joinery, decoration and all finishes. We don't quote for building work then add extras for interiors — it's all one price.
A full refurbishment touches every element of your home.
Removing and repositioning internal walls, creating open-plan spaces, adding en-suites, reconfiguring staircases and improving circulation. Our architects redesign the entire floor plan before a single trade enters the building.

Every room in a full refurbishment has its own technical requirements, specification decisions and sequencing considerations. Here is what is involved in each.
A full kitchen refurbishment begins with complete strip-out of existing units, flooring, wall finishes, electrics and plumbing. The space is then rewired with dedicated circuits for oven, hob, extraction, fridge-freezer and dishwasher, plus general socket circuits with USB provision. Plumbing is re-run in copper and plastic to new locations. The layout is redesigned for workflow efficiency — our kitchen designers follow the work-triangle principle while adapting to the specific proportions of your room. New installations include bespoke or premium cabinetry, stone or composite worktops, integrated appliances, feature lighting (under-cabinet, pendant, recessed), splashback tiling or glass, and engineered timber or stone flooring. Extraction is ducted to the outside. Underfloor heating is fitted beneath the finished floor.
Bathrooms require the most intensive waterproofing of any room in the house. We strip out all existing fittings, tiles and substrate, then apply tanking membrane to all wet areas (shower enclosures, bath surrounds, floors) before tiling. Underfloor heating is installed beneath porcelain or natural stone tiles. Plumbing is re-run to accommodate the new layout, often including relocation of waste stacks and soil pipes. Sanitaryware selection includes wall-hung WCs (for easier cleaning and a more spacious feel), freestanding or built-in baths, walk-in or wetroom showers with frameless glass enclosures, and twin basin vanity units. Heated towel rails, anti-mist mirrors, recessed LED lighting and extractor fans complete the specification.
Living rooms and reception rooms often involve structural alterations — removing load-bearing walls to create open-plan spaces, installing steel beams to support the floor above, and widening doorways to improve flow between rooms. Flooring is selected for acoustics and durability: engineered oak, natural stone or high-quality LVT. Lighting design layers ambient (recessed downlights or pendant fittings), task (reading lamps, desk lighting) and accent (picture lights, LED strips, uplighters) circuits on separate dimmer controls. Bespoke joinery — alcove shelving, window seats, media walls, fireplace surrounds — is designed to the proportions of each room. Walls are re-plastered to a smooth finish, and period features (cornicing, ceiling roses, dado rails) are restored or replicated where appropriate.
Bedroom refurbishment focuses on creating calm, well-organised spaces. Built-in wardrobes are designed floor-to-ceiling with internal fittings (hanging rails, shelving, drawers, shoe racks, lighting) tailored to how you dress. Acoustic insulation is installed in party walls and floors — particularly important in converted flats and terraced properties — using acoustic mineral wool and resilient bars to achieve meaningful sound reduction. Windows are overhauled or replaced: secondary glazing for listed properties, slim-profile double glazing for conservation areas, or high-performance triple glazing where planning allows. Blackout blinds, layered lighting (bedside, wardrobe, ambient) and smart controls complete a restful environment.
The hallway sets the tone for the entire house. In period properties, we restore original encaustic or geometric floor tiles, repair and French-polish timber balustrades, rebuild newel posts and reinstate panelled wainscoting or dado rails. Where the original features have been lost, we commission faithful reproductions from specialist joiners. Stair treads are repaired and finished in matching timber, with runners fitted for noise reduction and grip. Lighting is critical: a combination of pendant or lantern fittings, wall sconces and recessed lighting creates depth and warmth. Storage is built into dead space beneath staircases. Doorbells, entry systems, coat hooks, shoe storage and radiator covers are all specified as part of the design.
A dedicated utility room is one of the most requested additions in a full refurbishment. We create space for washing machine, tumble dryer (or washer-dryer), sink, drying rack, ironing station and cleaning supply storage. Plumbing and extraction are run to the utility room during first fix. Where space permits, a separate pantry with open shelving, cold storage and counter space significantly improves kitchen functionality. Plant rooms house the boiler (or heat pump indoor unit), hot water cylinder, consumer unit and any home automation hardware — keeping services accessible for maintenance while hidden from living spaces. Every cupboard and storage area is fitted with lighting and considered as part of the overall design.
On most London streets this is a genuinely open question. In NW11 it rarely is. Hampstead Garden Suburb is a planned Arts and Crafts masterpiece and one of the most tightly-protected residential areas in the country, lying almost entirely within the Hampstead Garden Suburb Conservation Area — the largest conservation area in the London Borough of Barnet — with a high concentration of listed buildings, including Lutyens' work around Central Square.
Why refurbishment is the route here. The existing fabric is the reason the Suburb is protected in the first place, and four separate controls sit over it:
Taken together, these make demolition and rebuild an unlikely proposition on a Suburb plot, and they make the real decision a different one: how deep the refurbishment goes. That ranges from a cosmetic programme that renews services, bathrooms and heating while leaving the plan and the elevations alone, through to a back-to-brick scheme that reworks structure, insulation and layout behind an external envelope which stays exactly as it is. Both are refurbishment. Both begin with the same conversation about what Barnet and the Trust will accept.
Not every property is best served by refurbishment. Here is how to decide whether to refurbish the existing structure or demolish and rebuild.
Refurbishment is the right choice when the existing structure is fundamentally sound — solid walls, stable foundations, a serviceable roof. It is also the preferred route when the property has period features worth preserving (original cornicing, ceiling roses, fireplaces, panelled doors, timber floors), when planning restrictions make demolition difficult or impossible (listed buildings, conservation areas), or when budget constraints favour working with the existing shell rather than starting from scratch. Most London period properties — Victorian terraces, Georgian townhouses, Edwardian semis — fall firmly into the refurbishment category.
Demolition and rebuild is justified when the existing structure has significant defects — severe subsidence, failed foundations, widespread dry rot affecting the structural timber, or extensive asbestos contamination that makes strip-out more expensive than demolition. It may also make sense when the desired layout is so radically different from the existing building that the structural alterations required would cost more than rebuilding. In some cases, a Whole Energy Retrofit analysis may show that the existing building fabric is so thermally poor that a new build to current standards offers better long-term value.
A comprehensive refurbishment typically costs £650–£1,250/sqm depending on specification level. A demolition and rebuild (excluding land value) costs substantially more per square metre. However, the rebuild figure includes foundations, superstructure, roof, external walls and all services — elements that already exist in a refurbishment. The decision should be made on a case-by-case basis following a thorough structural survey. We provide honest advice on which route offers the best outcome for your specific property.
A Suburb programme runs in a different order from a refurbishment on an unprotected street, because two separate consents sit in front of the build and the external envelope is largely fixed before a single trade arrives.
Two sequencing errors cause most of the trouble here. The first is ordering windows, render or roof materials before the Trust and Barnet have both signed off, which turns a specification into a dispute. The second is treating the garden, verge and boundary as post-completion tidying, when they are governed by the same consents as the house and are the first thing the street sees.
The order in which trades enter the building is critical. Getting the sequence wrong causes delays, rework and damage to finished surfaces. Here is the correct order and why it matters.
Everything that is being replaced is removed: kitchens, bathrooms, floor coverings, old plaster, redundant electrics and plumbing, partition walls. The building is taken back to its structural shell. This reveals the true condition of the property — hidden damp, rotten timbers, failed lintels, asbestos — allowing problems to be addressed before new work begins. Skipping a thorough strip-out is the most common cause of cost overruns, because defects discovered after new work has started require expensive rework.
Load-bearing walls are removed and steel beams installed. Floors are strengthened, lintels replaced, timber joists sistered or renewed. Any underpinning, foundation work or damp-proofing is completed at this stage. Structural work must be finished and signed off by building control before first fix begins, because the building must be structurally stable before services are installed within it.
New electrical cables are run to every socket, switch, light fitting and appliance position. Plumbing pipes are run to every tap, WC, bath, shower, washing machine and boiler location. Heating pipework (radiators or underfloor) is laid. Ventilation ductwork is installed. First fix happens before plastering because all cables and pipes need to be concealed within the walls and floors. Getting the positions right at this stage is critical — moving a socket after plastering means cutting out plaster, re-routing cable and re-plastering.
Walls and ceilings are plastered to a smooth finish over the first-fix services. This creates the final surface for decoration and must be done to a high standard — imperfections in plaster are visible through paint. Plaster must dry thoroughly (typically 2–4 weeks depending on season and ventilation) before decoration begins. Rushing this stage leads to paint failure and mould. We monitor moisture levels with a hygrometer and do not begin decoration until readings are within tolerance.
Electrical face plates (sockets, switches, light fittings) are installed. Bathroom and kitchen fittings are connected. Radiators or underfloor heating thermostats are fitted. Doors are hung, ironmongery fitted, skirting boards and architraves installed. This stage brings the house from a building site to something recognisable as a home.
Kitchen units, worktops, splashbacks and appliances are installed. Bathrooms are tiled, sanitaryware fitted, screens and mirrors hung. These are the highest-specification elements of the refurbishment and require careful protection during subsequent decoration work.
Walls are mist-coated (to seal new plaster), then finished with two coats of emulsion. Woodwork is undercoated and gloss-finished (or eggshell for a contemporary look). Ceilings are painted. Wallpaper is hung where specified. This stage must happen after all dusty trades (plastering, tiling, sanding) are complete to avoid contamination of wet paint surfaces.
A detailed room-by-room inspection identifies any defects: paint touch-ups, alignment adjustments, scratches, incomplete seals, stiff handles, squeaky floorboards. Every snag is logged, photographed and rectified before handover. We provide a full handover pack including appliance manuals, paint references, material specifications, electrical certificates, gas safety records and a 12-month defects liability warranty.
The Suburb is a planned Arts and Crafts masterpiece and one of the most tightly protected residential areas in the country, so approvals in NW11 run on more than one track. Almost the whole area falls within the Hampstead Garden Suburb Conservation Area — the largest conservation area in the London Borough of Barnet — with Article 4 controls in force and around 500 individually listed buildings. At Central Square, Lutyens' St Jude's and the Free Church are Grade I, and most other buildings around the square are Grade II* or Grade II.
The second layer is the decisive one. Most of the Suburb is subject to the Hampstead Garden Suburb Trust's Scheme of Management, a covenant system established under the 1967 Leasehold Reform Act, which allowed ground landlords of selected well-run estates to apply to the High Court for such a scheme. The Trust is empowered to control changes to the appearance of the area's buildings and landscapes, so its consent is needed for external alterations — windows, doors, render, roof, even hedges and front-garden changes — separately from, and in addition to, Barnet planning.
Barnet's controls are exacting on materials, windows, roofs and extensions, and building control sign-off on the technical works runs alongside those design consents rather than replacing them. Getting both right, in the right order, is the single most important part of a Suburb project.
Not every refurbishment requires building regulations approval, but many elements do. Here are the key Approved Documents that commonly apply.
Any electrical work in a dwelling must be carried out by a Part P registered electrician or notified to building control. A full rewire, new consumer unit, new circuits, or work in bathrooms and kitchens all require Part P compliance. On completion, you receive an Electrical Installation Certificate and the work is registered on the national database. We use Part P registered electricians on every project and provide full certification as standard.
When you replace more than 25% of a thermal element (roof, walls, floors, windows), the replacement must meet current thermal performance standards. This means if you are replastering walls, you may need to add insulation to meet the required U-values. Similarly, window replacement triggers minimum energy performance requirements. In a full refurbishment where all elements are being renewed, a SAP assessment may be required to demonstrate overall energy performance. We design insulation strategies that improve thermal performance without compromising room proportions or period character.
If you are refurbishing a flat within a converted building, fire safety regulations apply to the means of escape. Fire doors (FD30S) must be fitted to all habitable rooms opening onto a communal hallway. Smoke detection systems must comply with BS 5839. Fire-resistant construction may be required to walls and ceilings separating your flat from communal areas and other dwellings. Where structural alterations create new openings in fire-separating elements, fire stopping must be installed to maintain compartmentalisation.
When converting a house into flats, or refurbishing an existing flat conversion, Part E requires minimum acoustic performance between dwellings. This typically means upgrading floor and wall constructions to achieve specified airborne and impact sound insulation values. Even in a single dwelling, acoustic insulation between bedrooms and living spaces significantly improves comfort. We specify acoustic mineral wool, resilient bars, acoustic plasterboard and floating floor systems where required to achieve or exceed the minimum standards.
A structured process ensuring nothing is missed.

Need a same-day repair in NW London?
Visit Hampstead On Demand →We bought a tired 1890s terrace and appointed Hampstead Renovations before exchange. They started the day we got the keys. Eighteen weeks later we moved into a home that felt like it had been built for us — the layout is completely different but every period detail respected. The interior design continuity room to room makes the whole house feel intentional.
The 3D room renders were game-changing. We could see exactly how the herringbone floor, wall colour, pendant lights and joinery worked together before orders were placed. We made two changes in design that would have cost thousands on site. The fixed price held exactly across 22 weeks and 240 square metres.
We refurbished our Maida Vale flat while renting it out — Hampstead managed everything without us visiting once during the 12-week build. The procurement coordination was extraordinary: every tile, fitting and piece of ironmongery arrived exactly when needed. Boutique hotel standard quality. Tenants moved in the day after handover.
Questions we are asked most often about full house refurbishment in Hampstead Garden Suburb, NW11.
Do I really need consent from the Suburb Trust as well as from Barnet?
In most of the Suburb, yes. There are two layers of control. Barnet handles planning and, where relevant, listed building consent. Separately, most of the Suburb is subject to the Hampstead Garden Suburb Trust's Scheme of Management, a system of covenants under which the Trust's consent is needed for external alterations. The two are independent of one another, and we manage both.
What does the Scheme of Management actually cover?
External change: windows, doors, render, roof — and, beyond the building itself, hedges and front-garden changes. It is broader than most owners expect, which is why external scope is confirmed before anything is ordered or stripped.
Where does the Trust's power come from?
The Scheme of Management was set up under the 1967 Leasehold Reform Act, which enabled the ground landlords of selected well-run estates to apply to the High Court for such a scheme. The Hampstead Garden Suburb Trust is empowered to control changes to the appearance of the buildings and land.
Is my house listed?
Around 500 buildings in the Suburb are individually listed, so it is a real possibility and always worth checking before design work starts. At Central Square, Lutyens' St Jude's and the Free Church are Grade I listed, and most other buildings around the square are Grade II* or Grade II listed. Listing changes what internal work can be done, not only external work.
Can I replace the windows and the front door?
Only on a consented basis, and like-for-like is the default. Roofs, windows, chimneys, render and doors are protected by both Barnet and the Trust, so authentic materials and correct detailing are essential — profiles, glazing bar sizes, finishes and fixings all matter as much as the overall shape.
Can I extend at the rear?
Rear extensions in NW11 are possible but are judged strictly. This is a low-density, visually disciplined residential quarter with broad routes, strong building lines, Edwardian facades, Arts and Crafts houses and a planned green character, so an extension has to respect the original house composition and its garden setting rather than simply maximise floor area.
What about the loft and the roofline?
Roof developments are one of the areas where Barnet's controls are most exacting, and the roof is protected by the Trust as well. Anything that alters the roofline is treated as a conservation question first — massing, pitch, materials and how it reads from the street and from neighbouring gardens.
Is a basement possible in the Suburb?
Basement work here divides into converting an existing cellar and excavating new space, and the two carry very different structural and procedural loads. Excavation brings underpinning, party wall procedure, garden levels, tree protection and site access on quiet residential streets into the same programme, so it is scoped early rather than added later.
How much can the internal layout change?
Considerably more than the outside, which is where most of the gain in a Suburb refurbishment comes from. These houses take sensitive whole-house refurbishment, careful extension and services renewal, so plans can be opened up, bathrooms relocated and circulation improved. Where the house is listed, internal features are part of what is protected, so the layout strategy is tested against that before drawings are finalised.
Does the Suburb's layout affect site logistics?
Yes. Careful access through established residential streets is part of every programme here. Broad routes, strong building lines, hedges and green verges mean that deliveries, scaffolding, skips and storage are planned rather than improvised, both to protect the front-garden character the Trust oversees and to keep quiet streets such as Meadway, Hampstead Way, Erskine Hill and Linnell Drive usable while the work runs.
Do trees and hedges affect the scheme?
Frequently. Trees and boundary treatment are planning considerations in the Suburb, and hedges and front gardens fall within the Trust's remit because the hedges and green verges are part of the original design intent. They influence both what can be built and how the site is accessed.
Will I need a party wall award?
Where structural openings, underpinning or excavation affect a shared or adjoining structure, party wall procedure applies as it does elsewhere in London. On Suburb plots it usually runs alongside the tree, boundary and access constraints, so neighbour notices are prepared as part of the same pre-build stage as the consents.
What drives the budget and the programme?
Conservation-led design, matching Edwardian or Arts and Crafts detailing, roof and facade interfaces, garden levels, trees and boundary treatment, structural openings, party walls and careful access through established residential streets. Scope is priced against a design that both Barnet and the Trust can accept, because a scheme that has not cleared those two tests is not yet a scheme.
Can I stay in the house while the work runs?
For a back-to-brick refurbishment it is impractical, since services, bathrooms and heating are out of action together. A phased, room-by-room programme is possible on lighter schemes, though external works, scaffolding and consented reinstatement still set the overall timetable.
Do you work in the surrounding areas?
Yes — alongside Hampstead Garden Suburb we work in neighbouring Hampstead, Highgate, Golders Green, Muswell Hill, Crouch End and Belsize Park, which share much of the same period stock and conservation-area thinking.
Common questions about full house refurbishment.
A typical full refurbishment of a 3–4 bedroom London property takes 12–24 weeks on site, depending on the scope of structural works, specification level and property size. A smaller flat (1–2 bedrooms) with no structural alterations can be completed in 8–12 weeks. Larger properties (5+ bedrooms) or projects involving basement or loft conversions may take 6–9 months. Add 4–8 weeks of design time before construction begins. We provide a detailed programme at the start of every project showing weekly milestones and key decision points.
For a full refurbishment — where every room is being stripped, rewired and replastered — we strongly recommend moving out. The property will have no functioning kitchen or bathroom during the works, dust levels are significant during strip-out and plastering phases, and the constant presence of trades makes daily living extremely difficult. Most clients either rent nearby, stay with family or use short-term accommodation. For partial refurbishments (one floor at a time), it may be possible to live in the unaffected part of the property, though this extends the programme and requires careful sequencing.
The terms are often used interchangeably, but in the construction industry, a refurbishment implies a more comprehensive scope than a renovation. A renovation might involve updating kitchens and bathrooms, redecorating and minor repairs — working with the existing layout and services. A full refurbishment typically means stripping the property back to its structural shell and rebuilding everything: new electrics, new plumbing, new heating, new layout, new finishes throughout. It is essentially creating a new home within an existing shell. Our full refurbishment service covers the complete scope from strip-out to handover.
Internal refurbishment work generally does not require planning permission — you can rewire, replumb, replaster, fit new kitchens and bathrooms, and redecorate without any planning application. However, planning permission is needed if you are: changing the external appearance of the building (new windows, changing door positions, removing chimneys), making structural alterations visible from outside, changing the use of the property, or working on a listed building (where Listed Building Consent is required for most internal and external works). In conservation areas, window replacement and external changes may also require planning consent.
Our full refurbishment costs typically range from £650–£1,250/sqm, depending on specification level. A standard refurbishment sits at the lower end of that range and includes complete rewire, replumb, plastering, new kitchen, new bathrooms, flooring and decoration to a good quality. A premium specification sits mid-range and adds bespoke joinery, designer kitchens, high-end sanitaryware, engineered timber flooring and architectural lighting. An ultra-premium specification sits at the top of that range and includes top-tier brands (Bulthaup, Lefroy Brooks, Dinesen), smart home systems, and bespoke everything. For a 150 sqm London house, expect total costs of £75,000–£180,000 depending on specification.
Our full refurbishment scope covers: architectural layout redesign, 3D visualisations, complete strip-out, structural alterations (wall removals, steels), full electrical rewire to 18th Edition, full replumb in copper and plastic, new heating system (boiler or heat pump), plastering throughout, new kitchen design and installation, new bathroom design and installation, flooring throughout (timber, stone, tile or LVT), bespoke joinery (wardrobes, shelving, media walls), staircase renovation, door replacement or overhaul, ironmongery, lighting design, decoration (paint, wallpaper), and snagging. Interior design specification is included as part of the package — not charged separately.
Yes, for most elements of a full refurbishment. Electrical rewiring must comply with Part P and be certified by a registered electrician. Structural engineering-led alterations (wall removals, new beams) require building regulations approval under Part A. Replacement windows must meet Part L energy standards. Heating installations must comply with Part J (combustion appliances) and Part L. In flats, fire safety (Part B) and acoustic (Part E) requirements apply. We manage all building regulations applications and inspections as part of our service, ensuring full compliance and providing all necessary certificates at handover.
Protecting original features is a priority on every period property refurbishment. Before strip-out, we conduct a detailed survey identifying features to retain: original cornicing, ceiling roses, fireplaces, floor tiles, timber floors, panelled doors, balustrades, stained glass and decorative plasterwork. These are either protected in situ with boarding, dust sheets and impact protection, or carefully removed, labelled and stored off-site for reinstatement. Our specialist plasterers can repair damaged cornicing and cast new sections to match existing profiles. Original timber floors are sanded and refinished. Fireplaces are restored, re-lined where necessary and fitted with appropriate grates or log burners. Where original features have been lost in previous unsympathetic alterations, we commission faithful reproductions from specialist craftspeople.
