GS Renovation refurbishes whole houses across Merton, from tired Victorian villas in Wimbledon to interwar terraces around Mitcham Common and Morden. We take a dated property back to brick where needed and rebuild it as one coordinated project.
In Merton, 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 Merton: 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 Merton and bathroom renovation in Merton. In the 58% of homes here that are houses, moving the kitchen usually means opening up the back of the ground floor, which is structural work.

Whole-house refurbishment in Merton homes
A full Merton renovation usually means rewiring, replumbing and replastering throughout, because the services in a Victorian, Edwardian or interwar house are often decades past their best. We sequence the trades so first fix electrics and pipework go in before the walls are closed up, then plaster, second fix and decoration follow in the right order. One team holds the whole programme together.
Reconfiguring the dated layout is where these houses come alive. We open the cramped rear rooms into the closet wing, rework the awkward bathroom that was squeezed in over the years, and rethink how a narrow SW19 terrace flows from front door to garden, all while keeping the building sound and warm.
Housing in Merton
For Merton the Council Tax list gives about 87,830 homes; by type 42% flats and 58% houses, by age 36% post-war, 37% interwar and 26% older than 1919. A mid-terrace in Merton has no side access, so strip-out goes through the hall, and 43% of homes here are terraced.
Reroofing and front gardens in Merton's protected streets
Merton's appraisal describes Mitcham Cricket Green as one of 28 designated conservation areas in the borough, designated as a conservation area in 1968. The appraisal says changes such as infilling of porches, change of roof covering and removal of front boundaries can cumulatively erode the area's special character. It also states the Council intends, when resources become available, to make an Article 4 Direction removing permitted development rights for these works. A whole-house renovation can include exactly those items, so in that part of Merton the specification keeps the roof material, the open porch and the front wall unless a change has been discussed with the council first.
Front gardens need the same care in John Innes Merton Park. The first John Innes Article 4 (2) direction withdraws permitted development for a hard surface within the curtilage of a dwellinghouse that would front a highway or other public space. That catches a renovation that paves the front garden for parking. The Upper Morden Conservation Area was designated by Merton Council in 1986, and there, as in any conservation area, side extensions, roof extensions and external cladding lose their permitted development rights. Check the address with the council before the renovation scope is priced, not when the skip arrives.
Restoring period features across the borough
Merton's bay-fronted terraces still hold cornicing, ceiling roses, picture rails, panelled doors and original fireplaces worth saving. Where these survive we protect and restore them, and where previous owners stripped them out we can reinstate mouldings that match the age of the house, so a refurbished Wimbledon home keeps its Victorian or Edwardian character and a Morden or Mitcham house keeps its interwar one.
Structural changes are woven into the same schedule. If the renovation includes a steel beam knock-through or a new opening, the engineer's design and building control sign-off are handled alongside the kitchen, bathrooms and decoration. That coordination avoids the stop-start delays that come from juggling separate contractors on an occupied Merton house.

FAQ
Frequently Asked Questions about Home Renovation Merton
How accurate is a home renovation quote for a Merton house?
Accuracy on a home renovation quote in Merton comes from surveying, itemising and standing behind the total within £40,000 to £150,000 or more (indicative). Quoting low to win a job and correcting it later is the commonest complaint about builders. GS Renovation prices in the order the work runs: strip-out comes before first fix, and first fix before plaster. Anything unforeseen is costed before continuing at SW19.
What should a written specification for a Merton renovation contain?
Enough detail that two contractors would price the same job. For your Merton property that means the extent of each trade, the materials and fittings by name where they are chosen, what is included in making good, and what has been excluded. Vague scopes produce quotations that cannot be compared and variations later. We price from a written scope that sets out what is not in it.
How are payments arranged on a Merton renovation?
In stages tied to work completed rather than to dates. On a Merton project each stage is defined in advance, and payment follows once that stage is finished and inspected. A large payment up front is a warning sign in any building contract. The arrangement is written down before work starts, alongside what happens if the scope changes during the job.
What happens at the end of a Merton renovation?
A joint inspection and a snagging list. Walking a completed Merton project with the owner produces a written list of everything needing attention, from a door that binds to paintwork that needs a further coat. Those items are worked through and signed off rather than left to correspondence. Certificates for electrical and gas work and any building control paperwork are handed over at the same time.
How is a Merton property protected while the work goes on?
By covering and separating before the first tool comes out. In your Merton house that means protecting floors and the stair on the access route, sealing off rooms not in the scope, covering fittings that are staying and securing the property at the end of each day. Dust travels much further than most owners expect. Protection costs very little and prevents most of what people complain about afterwards.
Does a Merton renovation need a party wall award?
Where the work affects a shared wall or excavates near a neighbour's foundation, notice is required and an award usually follows. That covers beams bearing into a party wall, chimney breast removal on a shared stack and foundations for an extension close to the boundary. The owner serves the notice rather than the contractor, and the timetable is started early because it cannot be compressed.
Can the roof covering change during a renovation in Mitcham Cricket Green?
The appraisal flags it. It says change of roof covering can cumulatively erode the area's special character, and it states the Council intends, when resources become available, to make an Article 4 Direction removing permitted development rights for these works. Matching the existing material, and checking with Merton Council before ordering, avoids a problem if the direction is made while the project is running.
Can the front garden be paved during a renovation in the John Innes Merton Park area?
Not under permitted development where it faces the street. The first John Innes Article 4 (2) direction withdraws permitted development for a hard surface within the curtilage of a dwellinghouse that would front a highway or other public space. So a new parking space at the front needs a planning application. During the works, a skip on the road under a licence avoids creating a new hard surface.
Is a newer Merton home simpler to renovate than an older one?
In some ways. 12% of homes in Merton were built in 2000 or later, and a house of that age normally has cavity walls, modern wiring and plasterboard linings, so a renovation is more about layout and finishes than repair. The catch is that walls may be timber frame or blockwork with services buried in them, so find the original build drawings before any wall is opened.
