GS Renovation carries out whole-house refurbishments across New Malden, where interwar semis in KT3 often reach us with dated wiring, tired plumbing and small, boxed-off rooms. We take these 1930s homes back to a blank canvas and rebuild them around how families actually live today.
In New Malden, 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 New Malden: 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 New Malden and bathroom renovation in New Malden. In the 69% 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 for New Malden homes
A full renovation of a New Malden semi usually means rewiring throughout, replacing the original plumbing, replastering walls and ceilings, and reconfiguring the compartmentalised 1930s layout into more open, connected space. We run all of this as one managed project, so the electrician, plumber, plasterer and joiner work to a single sequence rather than tripping over each other in an occupied KT3 house.
Interwar homes here still carry features worth keeping, such as picture rails, deep skirtings, panelled doors and stained glass. Where you want them, we restore these period details and match new joinery to them, so the refurbished house feels true to its 1930s character while the services behind the walls are brought fully up to modern standard.
Housing in New Malden
New Malden's housing, as the Council Tax list records it, is about 7,070 homes: 69% houses, 31% flats, with 33% pre-1919, 33% interwar and 34% built since 1945. Semi-detached houses make up 31% of homes here, and a semi in New Malden usually has side access.
Three building eras and one New Malden renovation plan
New Malden's homes divide into near equal thirds by age: those built before 1919, those built between the wars, and those built after 1945. For a whole-house renovation that split matters, because walls, floors and services were put together differently in each period. A house from before the First World War is likely to have solid brick walls that need to dry outwards, so internal insulation and plaster are chosen to let moisture escape. An interwar house needs its cavity checked before anything is filled. A postwar house can have a concrete ground floor, which changes how new pipes and underfloor heating are routed. Establish the era before choosing materials.
A renovation also reaches the outside: windows, front doors, porches, garden walls and render. In Kingston's conservation areas, demolishing a wall or making an external alteration needs the council's approval, so check with the council before replacing original windows or taking down a front garden wall there. On New Malden streets that are Local Areas of Special Character, Kingston says permitted development rights are not affected, so the same changes follow the ordinary rules. Confirm which applies before ordering windows, because a factory lead time running ahead of a consent decision is one way for a renovation to stall with the scaffold still standing.
Sequencing structure and finishes in KT3
The value of one team on a New Malden renovation shows in the order of works. We start with any structural changes, such as a steel beam to open the ground floor, then first-fix the wiring and pipework, plaster, and only then move on to kitchens, bathrooms, flooring and decoration. Getting that sequence right avoids the reworking and delays that plague projects run by separate trades.
Because we coordinate everything, the Building Regulations side is handled cleanly too, with Kingston Council building control inspecting the structural work and a registered electrician certifying the notifiable electrics at the right moments. You deal with one point of contact for the whole KT3 refurbishment, from the first strip-out to the final snagging list, and one team stands behind the finished result.

FAQ
Frequently Asked Questions about Home Renovation New Malden
Can you quote home renovation for a KT3 property over the phone?
A rough steer on home renovation in New Malden is possible by phone; a quotation is not. The steer is £40,000 to £150,000 or more (indicative), and the figure waits until the KT3 property has been seen, because 1930s suburban construction rarely matches the assumption. The call also covers the approvals: Kingston Council building control inspection of any structural and drainage work. Ring 07472 424 226 or email info@gsrenovationltd.co.uk.
Can you renovate my whole New Malden house while keeping its 1930s character?
Yes. We rewire, replumb and replaster interwar KT3 semis while carefully retaining and restoring period features like picture rails, panelled doors and stained glass. New joinery is matched to the originals, so the house gains modern wiring, plumbing and layout without losing the 1930s character that makes New Malden homes so appealing.
Which building control notifications does a New Malden renovation trigger?
Only the notifiable slices of it. Fresh circuits, plus circuit changes around the bath or shower, sit under Part P, with the electrician's own registration covering the paperwork. Taking out a load-bearing wall or a breast is structural and goes through Part A. Extract fans answer to Part F, and upgrading an outside wall as a thermal element pulls in Part L. Replacement units, floors and paint trigger nothing.
Should the boiler be decided early in a New Malden refurbishment?
Yes, before first fix. Swapping a regular boiler and cylinder for a combi, or the reverse, changes pipe sizes, where hot water is stored and whether the airing cupboard survives. Those choices steer the plumber's first fix and the bathroom layout. Deciding after the walls are plastered means chasing them twice, and all gas work is done by a Gas Safe registered engineer.
Does an interwar New Malden house need an asbestos check before work starts?
It should have one. Anything built before 2000 can contain asbestos, and VOA puts 33% of New Malden's homes as interwar, with another 33% older still. Textured ceilings, floor tiles, flue pipes and panels near old boilers are the usual suspects. The survey goes before strip-out, so any removal is finished before other trades arrive.
Which rooms should be tackled first in a New Malden whole-house job?
The work that spreads dust and disruption everywhere: structural openings, the rewire and pipe runs through the house. After those, the kitchen and a bathroom are usually finished first so the house is liveable, then bedrooms and decoration. Completing one room before the rewire means cutting into new plaster for cables later, a false economy that catches plenty of owners.
Which Kingston building control route suits a New Malden renovation with several notifiable jobs?
Kingston charges the same for full plans or building notice, so choose on control rather than cost. A renovation combining a removed wall, a new en-suite and a garage conversion gives the inspector several items, and approved drawings keep every trade working to one agreed design. After validation Kingston sends a Service Plan listing the stages at which inspections must be booked. On a whole-house job that list becomes the backbone of the programme.
Which New Malden streets are Local Areas of Special Character?
Kingston lists Elm Road, Lime Grove, The Berg Estate and Thetford Road under New and Old Malden, out of 19 Local Areas of Special Character across the borough. Kingston says permitted development rights are not affected in one, so this is a different status from a conservation area. For a renovation on those streets, windows, doors and porches follow the ordinary permitted development rules unless the address is also inside a conservation area or under an Article 4 direction.
Does a New Malden house built in 2000 or later still need an asbestos survey before renovation?
Asbestos is far less likely in one. 9% of homes in New Malden were built in 2000 or later, after the UK had banned asbestos in new building materials. A survey is still sensible where the house has been extended or had older fittings reused, or where the build date is uncertain. For a house of that age, the more useful early checks are the builder's drawings, the joist type and where the services run.
