Flat Refurbishment in Hampstead: What You Need to Know
A Hampstead flat refurbishment has a different risk profile from a house refurbishment. The design must satisfy the client, the freeholder, the managing agent, neighbours, Building Control and often Camden, while the site team works through shared entrances, stairwells, lifts and restricted working hours.
We build the programme around leasehold approvals: Licence to Alter drawings, structural notes, acoustic build-ups, floor protection, waste routes, deliveries, RAMS, fire stopping, ventilation and water shut-offs. That planning work is what keeps mansion block and period conversion projects from becoming neighbour disputes.
The finished flat is handled as a complete interior: layout, storage, kitchen, bathrooms, lighting, acoustic flooring, joinery, decoration and final certification under one project manager.
Hampstead keeps a deep reserve of mansion flats and period conversions alongside its famous houses, and refurbishing them is a discipline of its own. A flat here is usually one part of a grander original — a mansion block built as apartments, or a villa long since divided — and the refurbishment has to respect both the home you own and the building you share.
That is why the consents come layered. A Licence to Alter from the freeholder runs alongside any Camden approvals; where the building is listed, consent extends to internal change, not just external; and with almost all of Hampstead inside the Hampstead Conservation Area under Article 4 directions, anything the refurbishment shows to the street is a planning matter. We sequence licence, consent and design together rather than in series.
On budget, the Camden headline for a full flat refurbishment is £60,000–£110,000 excluding VAT. Where a project lands depends less on the postcode than on the building's demands — and because a Hampstead refurbishment is so often about consent and coordination, we cost the approvals path with the same rigour as the construction.

What a Flat Refurbishment Involves
Refurbishing a flat means renovating inside a building you share — so the job is as much about leases, neighbours and building rules as it is about kitchens and finishes. We plan every project around the consents your lease demands and the protocols your block expects, then deliver the technical work under one fixed-price contract. A typical scope covers the elements below.
- Licence to Alter — lease review, application pack and freeholder’s surveyor queries handled on your behalf
- Acoustic build-up — separating floors and walls upgraded to meet Building Regulations Part E and any stricter freeholder schedule
- Wet-room tanking — certified waterproofing beneath every bathroom, flood-tested before tiling and covered by a 12-month defects period
- Rewire & replumb — new circuits, pipework and heating, coordinated with the building’s risers and stacks
- Layout changes — internal openings engineered, approved by building control and cleared with the freeholder where the lease allows
- Kitchens & bathrooms — designed, supplied and fitted to the specification tier you select
- Period detail — cornicing, sash windows and fireplaces retained and repaired in conversion flats
- Block protocols — lift protection, booked deliveries, restricted noisy hours and daily cleaning of communal areas
How We Run Your Project
Six stages, sequenced so freeholder consent never holds up the start on site.
- Survey & lease review — we measure the flat, inspect the services and read your lease to identify exactly which consents apply.
- Design & consents — our architects develop the layout while the Licence to Alter application runs in parallel, not afterwards.
- Fixed-price contract — an itemised specification agreed in full, with the acoustic and tanking details written in.
- Strip-out & first fix — soft strip, structural openings, cabling, pipework and the acoustic carcass, all removed and delivered through agreed routes.
- Second fix & finishes — kitchen, bathrooms, joinery, flooring and decoration.
- Testing & handover — snagging, certification and reinstatement of any communal areas before the keys come back to you.
Read the full flat refurbishment guide for flat typologies, specification tiers and the Licence to Alter process in detail.
Almost every leasehold flat needs formal freeholder consent — a Licence to Alter — before structural work, new flooring or services alterations can begin, and proceeding without one puts your lease at risk. Building Regulations apply on top: Part E sound insulation between dwellings, electrical and heating sign-off, and fire safety where walls or floors are opened. Flats and maisonettes also have no permitted development rights, so external changes always need a planning application. Our planning guide library covers the rules borough by borough.
Why Hampstead Renovations
Flat refurbishment rewards a team that already knows what freeholders and managing agents will ask for. Design is led by our in-house RIBA Chartered Architects, lease and party-structure matters are supported by RICS surveying through our sister company, Hampstead Chartered Surveyors, and the build is carried out by our own long-standing teams. Every contract is fixed-price on JCT terms, backed by £10M public liability insurance — the level major London freeholders require — plus a 12-month defects period and a 10-year workmanship warranty. Enquire before 2pm on a weekday and we will call you back the same day.

Flat Refurbishment in Hampstead: Questions
What is involved in refurbishing a flat in Hampstead?
Working on one piece of a larger building. Hampstead's flats sit in mansion blocks and period conversions — a deep local stock — so alongside the design itself the project manages the shared fabric, the freeholder relationship and the approvals, which is why refurbishment here is as much coordination as construction.
How much does a Hampstead flat refurbishment cost?
£60,000–£110,000 excluding VAT is the Camden headline we use for a full refurbishment of a two-bedroom flat. Treat it as the calibrated starting band: the lease, the building's fabric and your specification then move the figure to its real position.
Do I need a Licence to Alter for a Hampstead flat refurbishment?
Almost certainly, if the work goes beyond decoration. Leasehold flats in Hampstead need the freeholder's Licence to Alter running in parallel with whatever Camden requires — and where the building is listed, Listed Building Consent joins the list. We open the licence conversation with the freeholder at the start, because it is the consent most likely to set the timetable.
Does conservation-area status affect flats as much as houses in Hampstead?
At the envelope, yes. Almost all of Hampstead falls within the Hampstead Conservation Area with Article 4 directions removing many permitted-development rights, so windows and external alterations are controlled for a flat exactly as for a house — and in listed buildings, consent covers internal change too, floor by floor.
Our flat is in a converted Hampstead villa — anything special to plan for?
The conversion itself. Villas on streets like Fitzjohns Avenue and Netherhall Gardens were built as single houses, so services, sound and structure need reading as one system when a flat within them is refurbished — and with a high share of these properties leasehold, the freeholder's consent frames what the re-design can touch.

Local character & heritage: renovating flats in Hampstead
Hampstead sits in the London Borough of Camden, and a large share of its homes are leasehold flats — within Georgian and Victorian villas, period terraces and mansion flats. Refurbishing one is a full interior project: reconfiguring the layout, renewing services and finishes, and often combining or reworking rooms within the existing footprint.
The work runs under the lease, so the freeholder's or managing agent's consent sits alongside Building Regulations and the Party Wall Act usually applies between flats; external elements such as windows stay controlled in conservation areas. Because a high proportion of houses are statutory-listed and almost all of the village sits within the Hampstead Conservation Area, we coordinate the lease, the freeholder and the build as one fixed-price contract.

Flat Refurbishment in Hampstead: Planning & Local Context
London Borough of Camden · NW3
Planning for flat refurbishment in Hampstead
Flat refurbishment in Hampstead sits at the intersection of two consent regimes: London Borough of Camden for any planning or building-control matters, and your freeholder for a licence to alter covering structural changes, new services and floor build-ups — essential within the Hampstead Conservation Area and most mansion blocks.
London Borough of Camden & Hampstead Conservation Area context
Hampstead NW3 sits within the Hampstead Conservation Area, and Camden enforces Article 4 directions across its conservation areas (removing many permitted-development rights) and applies its CPG basement guidance to subterranean work. Our in-house RIBA Chartered Architects prepare and submit every application to London Borough of Camden and handle pre-application discussions where early planning advice is useful.
Building Regulations
Flat Refurbishment in Hampstead must satisfy Building Regulations — covering sound insulation to Part E, fire compartmentation to Part B, and certified electrical and plumbing works. Our in-house engineers manage Building Control from initial notice through to the completion certificate.
