GS Renovation refurbishes whole houses across Dulwich, taking tired Victorian and Edwardian terraces in SE21 and bringing them up to modern standards while keeping the character that makes them worth buying. We sequence the structural work, services, kitchens, bathrooms and decoration under one roof so nothing falls between trades.
In Dulwich, 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 Dulwich: 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 Dulwich and bathroom renovation in Dulwich. With 55% of homes in Dulwich flats, the soil stack usually fixes where a bathroom can go, and the lease may need the freeholder's consent for either room.

Whole-house refurbishment in Dulwich terraces
A full Dulwich renovation usually means going back to brick in places, rewiring throughout, replacing tired plumbing, and replastering walls that have been patched for a century. The bay-fronted terraces of East Dulwich often come with dated layouts, small dark kitchens in the closet wing and a bathroom squeezed onto a half-landing, so we rethink how the whole house flows before a single wall is touched.
Reconfiguring these homes commonly involves structural changes, opening reception rooms or the kitchen wall, which we handle with steel designed by the structural engineer we appoint and building control sign-off, as part of the same programme. Because we plan the sequence properly, the wiring, pipework, floor build-ups and plaster all land in the right order, so you are not paying to undo finished work later. One team means one point of accountability from strip-out to snagging.
Housing in Dulwich
Of the 14,360 homes the valuation list records in Dulwich, 56% were built before 1919, 11% between the wars and 30% since 1945; 55% are flats and 45% are houses. Most homes here are flats, and a whole-flat refurbishment in Dulwich works to the lease: the freeholder's licence for alterations, agreed working hours and sound insulation between floors.
Windows, doors and the Sunray Estate in a Dulwich renovation
A whole house renovation in Dulwich can reach the windows and back doors, and in a conservation area that is where Southwark's guidance is firmest. Southwark's Householder SPD says UPVC will not be permitted in any of the borough's Conservation Areas, even to the rear of a property. The Dulwich Village Conservation Area, designated on 7 September 1968, is one of those. A renovation that includes new glazing there should allow for the lead time of timber or metal joinery, and treat repair of the existing sashes as the first option.
The Sunray Estate on Denmark Hill, within North Dulwich, is a conservation area in its own right and is also subject to an Article 4 Direction confirmed by the Secretary of State on 13 November 1987. An Article 4 direction takes away specific permitted development rights, so external work that needs no application on a house elsewhere may need one here. Before a renovation schedule includes new front doors, windows, roof coverings or boundary walls on a Sunray house, read the direction and confirm with Southwark which items it covers.
Restoring period features across SE21
The Victorian and Edwardian houses of Dulwich were built with cornices, ceiling roses, picture rails, panelled doors and cast fireplaces, and much of it is worth saving. Where original features survive we protect and restore them, and where previous owners stripped them out we can reinstate sympathetic replacements so the house reads as it should. Good renovation here is as much about respecting the period as it is about modern services.
At the same time these are old buildings that need to breathe, so we deal with damp, ventilation and heat loss sensibly rather than sealing everything up. We upgrade insulation where it makes sense, improve the heating, and specify finishes that suit solid-walled construction. The result is an SE21 home that feels warm, dry and contemporary to live in while keeping the proportions and detail that give it value.

FAQ
Frequently Asked Questions about Home Renovation Dulwich
What drives the cost of home renovation in a Dulwich home?
Three things drive the cost of home renovation in a Dulwich home within £40,000 to £150,000 or more (indicative): how much structure is involved, access at the SE21 address, and making good afterwards. The biggest variable is usually hidden: how much of the Dulwich property is stripped at once decides how the trades are phased. GS Renovation prices each of the three separately rather than averaging across Southwark.
Can you renovate my Dulwich house while keeping the original features?
Yes, and it is what we recommend for these Victorian and Edwardian terraces. We protect and restore cornices, ceiling roses, fireplaces and panelled doors where they survive, and reinstate sympathetic replacements where they have been lost. Alongside that we rewire, replumb, replaster and reconfigure the layout, so your SE21 home keeps its period character while gaining modern services and comfort.
In what order do the trades work on a Dulwich whole-house renovation?
Strip-out, structure, services, then plaster. Once the house is cleared back and anything flagged by the asbestos survey removed, steel and joist repairs go in. Electricians and plumbers then first fix, running cables and pipes through open walls and floors. Only after that do plasterers close up, followed by second fix: sockets, radiators, sanitaryware and the kitchen. Out of order, a period SE21 house ends up with chases cut into new plaster.
Do I need an asbestos survey before renovating my Dulwich home?
Yes, before strip-out begins. Any building from before 2000 can contain asbestos, and VOA figures put 56% of Dulwich homes before 1919 with 30% built since 1945, many of them altered over the decades with textured ceilings, floor tiles, flue pipes and boards. A survey locates it so removal is planned before walls and floors are opened, rather than stopping the job halfway through.
How should damp be handled in a solid-walled Dulwich house?
Let the walls breathe before blaming the damp course. Solid brick period walls in SE21 manage moisture by drying through their faces, so cement render, gypsum plaster and impermeable paint added over the years trap it. The usual fixes are lowering outside ground levels, clearing air bricks under timber floors, repairing gutters and using breathable plaster. Kitchen and bathroom extraction ducted outside cuts moisture at source.
Should we move out during our Dulwich renovation?
If the scope includes a full rewire, replumb and new heating, usually yes. Once power and water are off for first fix and floorboards are up throughout, the house is hard to live in and trades work slower around you. For smaller scopes, phasing floor by floor lets you stay, though the point when the kitchen and main bathroom are out together is when most Dulwich households choose to leave.
Who pays for new windows when a Dulwich flat is renovated?
Check the lease before ordering. 55% of homes in Dulwich are flats, and in a converted house the windows may belong to the flat or may be part of the building the freeholder repairs. Where they are the freeholder's, replacement needs their consent and may be done as part of a block programme instead. The lease plan and the repairing clauses answer it, and they are worth reading before the renovation budget is fixed.
Should original steel windows be kept in an interwar Dulwich house renovation?
Where they survive, repair is worth pricing first. 11% of homes in Dulwich were built between 1919 and 1939, a period when slim steel window frames came into use. Corroded frames can often be cleaned, treated and reglazed, and secondary glazing inside improves warmth without changing the outside. Replacing them with thick modern frames alters the look of the house, which matters in a conservation area, where Southwark's SPD also rules out UPVC.
Was a Dulwich renovation designed before July 2025 checked against the current Householder SPD?
Probably not, so check it now. Southwark's Cabinet decided to adopt the Householder Development Supplementary Planning Document at its meeting of 07/07/2025. Drawings and advice prepared before that date were written against the earlier guidance. Internal renovation of an unlisted house is a building regulations matter, but the external parts of a scheme, such as windows, rear additions and roof changes, should be read against the adopted document before anything is submitted or ordered.
