Home Renovation Hampstead

GS Renovation carries out full refurbishments of houses and flats across Hampstead, from period cottages in the village and substantial Victorian villas to the apartments and mansion flats that make up most NW3 homes. One team rewires, replumbs, replasters and reconfigures the layout, sequencing the structural work, the kitchen, the bathrooms and the decoration so the project runs as a single coordinated build.

In Hampstead, a full house refurbishment typically costs £40,000 to £150,000 or more (indicative London ranges, MyBuilder and Checkatrade, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Hampstead: we carry the structure, services and finishes as one contract.

The two rooms that cost the most have their own pages, with prices: kitchen renovation in Hampstead and bathroom renovation in Hampstead. With 78% of homes in Hampstead flats, the soil stack usually fixes where a bathroom can go, and the lease may need the freeholder's consent for either room.

Full refurbishments in Hampstead terraces

A typical Hampstead whole-house project starts with stripping back a tired home to sort the fundamentals, a full rewire, new plumbing and heating, and fresh plaster throughout. We reconfigure the dated cellular layout of a Victorian house, opening the ground floor with a steel beam where a wall is load-bearing, and rethinking how the closet wing and side return can give a better kitchen and utility.

Sequencing is what keeps these projects on track. We plan first fix, structural work, second fix and finishes in the right order so trades are not tripping over one another in a house that may still be partly occupied. On the tighter streets near the Heath, we manage deliveries, skips and parking carefully, keeping disruption to neighbours and to Camden's roads to a minimum. Most Hampstead homes are flats, and an apartment refurbishment follows the same order with the lease added at the start: the freeholder's licence before any wall, kitchen or bathroom moves, working hours agreed with the managing agent, and acoustic upgrades to the floor while the boards are up, so the flat below hears less of you afterwards.

Housing in Hampstead

Hampstead has around 11,670 homes on the Council Tax list: 27% post-war, 10% interwar and 63% predate 1919, with 78% flats and 22% houses. Since most homes here are flats, a whole-flat refurbishment in Hampstead works to the lease: the freeholder's licence for alterations, agreed working hours and sound insulation between floors.

Three heritage checks before a Hampstead renovation starts

A whole-house renovation in Hampstead touches more of the building than any single job, so the protections on the house matter more. There are three to check. Is the house on the statutory list, since any change to a listed building needs listed building consent? Is it on Camden's Local List of non-designated heritage assets? And is it inside one of the 40 conservation areas that cover about half of the borough? Listing and conservation area status change what a renovation can do without an application, the Local List matters once one is made, and all three are quicker to confirm than to guess.

Inside an unlisted house, rewiring, replumbing, new plaster and a new kitchen need no planning permission, though new circuits and drainage come under the building regulations. The external items in a renovation are the ones that catch people out: replacement windows, a new front door, a rooflight or fresh render. In a conservation area, where an application is needed it must include a heritage statement describing the significance of the heritage assets affected. We schedule every external item at the start, so the ones that need an application are drawn and submitted before the trades reach them.

Restoring period features in NW3

The character of a Hampstead home lives in its details, the cornicing, ceiling roses, panelled doors, sash windows and cast-iron fireplaces. Where these survive we repair and reinstate them, matching profiles and mouldings so a renovated room still reads as Victorian or Edwardian. Where they have been lost under decades of alteration, we can reintroduce sympathetic replacements that suit the age and proportions of the house.

Restoration sits alongside modern comfort. We upgrade insulation, draught-proof the original sashes rather than rip them out, and hide new wiring, pipework and underfloor heating within the fabric so the period look is preserved intact. The result is a home that keeps the warmth and craftsmanship so valued across NW3 while quietly performing like a house built for how families actually want to live today.
