GS Renovation carries out whole-home refurbishments across New Cross, where most homes are flats, many in converted period houses, alongside SE14's terraces. We manage rewiring, replumbing, replastering and layout changes with one team, restoring period detail while bringing these homes up to modern standards.
In New Cross, 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 Cross: 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 Cross and bathroom renovation in New Cross. With 72% of homes in New Cross 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 New Cross terraces
A full renovation in a New Cross terrace usually means stripping the house back and starting with the services. Decades-old wiring and lead or corroded pipework get replaced, first fix electrics and plumbing are run in, and the house is completely replastered before any finishes go on. Because these SE14 homes have solid walls and suspended timber floors, we plan insulation, damp treatment and ventilation carefully so the fabric can still breathe.
Managing everything under one team is what keeps a whole-house project moving. We sequence the structural work, the kitchen, the bathrooms and the decoration so trades follow each other cleanly rather than clashing. That coordination matters in an SE14 terrace where the rooms are compact and every stage depends on the one before, and it means a single point of contact for you from strip-out to snagging.
Housing in New Cross
The Council Tax list puts New Cross at about 12,080 homes, 72% flats against 28% houses; 43% went up before 1919, 2% between the wars and 49% after 1945. Where most homes are flats, a whole-flat refurbishment in New Cross works to the lease: the freeholder's licence for alterations, agreed working hours and sound insulation between floors.
Turning a divided New Cross house back into one home
Some New Cross renovations start with a house that has been split into flats or let as rooms, and the plan is to make it one family home again. While the building is divided, Lewisham treats it as flats: flats or subdivided houses in conservation areas do not have permitted development rights and must seek planning permission for changes to the exterior. In the Hatcham conservation area that covers new windows and rear doors. Back in use as a single dwelling house, it regains householder permitted development rights, though a conservation area still excludes side extensions, rear extensions of more than one storey, roof extensions and cladding. Map the position before and after the change at the start.
Lewisham says its Article 4 directions in conservation areas only apply to houses that are in use as a single dwelling house. It lists alterations to the roof of a house and the addition of a porch among the changes they can bring under control. So a New Cross house reverting from flats may move into an Article 4 direction that did not touch it before. Ask Lewisham whether one covers the street before the renovation programme includes roof work or a new porch, and whether the change back to one house needs permission of its own.
Restoring period features and layouts in New Cross
Many New Cross owners want their period terrace or flat to work like a modern home while keeping the character that made them buy in SE14. We restore or reinstate cornicing, ceiling roses, panelled doors, skirtings and cast-iron fireplaces where they survive, and match new joinery to the original profiles when they do not. These details are part of why SE14's Victorian and Edwardian streets are so sought after.
Alongside the restoration we reconfigure dated layouts for how families actually live. That often means opening the rear reception into the kitchen with a properly sized steel beam, reworking a tired closet wing, or carving an extra bathroom out of an awkward return. Where those changes touch a load-bearing or party wall we handle the engineering and the building control sign-off as part of the whole.

FAQ
Frequently Asked Questions about Home Renovation New Cross
What is included in your home renovation price in New Cross?
Every home renovation quotation for a New Cross property lists the structural work, the following trades, the Lewisham Council building control inspections and the making good, inside £40,000 to £150,000 or more (indicative). Site protection and the daily clear-up at SE14 are included. The scope is written against what decides the job, because the age of the wiring decides whether a rewire comes first.
Can you renovate my whole New Cross house while keeping the period features?
Yes. Across SE14 we refurbish Victorian and Edwardian terraces top to bottom while protecting and restoring cornicing, fireplaces and original joinery. We rewire, replumb and replaster, then reconfigure the layout to suit modern living. Internal renovation does not need planning permission, though new circuits are notifiable under Part P and certified by a registered electrician, and structural changes need building control approval, which we manage for you. A listed building is the exception: work that affects its character, inside or out, including an extension or taking out a wall or chimney breast, needs listed building consent from Lewisham Council, and doing it without consent is a criminal offence.
What consents does a full renovation of a New Cross leasehold flat need?
Usually the freeholder's written consent before anything structural, or before moving the kitchen or bathroom. New circuits come under Part P and are certified by a registered electrician, and new extraction must be ducted outside under Part F. Any wall removal needs building control approval. Collect these before the programme is fixed, because a consent delay stops every trade behind it.
How is damp handled in the solid walls of a New Cross Victorian house?
By letting the walls dry rather than sealing them in. The solid brick of an SE14 terrace takes on moisture and needs a route out, so outside ground levels, leaking gutters and blocked air bricks are cured first. Breathable plaster and paint follow, and any insulation is chosen to suit solid masonry. Renovating an outside wall that way also brings in Part L.
Is an asbestos survey needed before renovating a post-war New Cross flat?
Yes. About half of New Cross homes were built after 1945 on the VOA figures, and anything from before 2000 can contain asbestos: textured ceilings, floor tiles, panels behind boilers, boxing around risers. The survey comes before strip-out. If it finds anything in shared ducts or common areas, removal involves the freeholder, which is another reason to survey early.
Which rooms come first in a New Cross whole-home renovation?
Structure, services and wet rooms, then everything else. Wall removals and steel go in first, followed by first fix plumbing and electrics throughout. Bathrooms and the kitchen are planned early because their waste runs set the pipe routes. After plastering, finishing usually starts at the top of the house and works down, so completed rooms are not walked through by trades.
Can Lewisham advise on replacing sash windows in a New Cross house before the renovation?
Yes. Lewisham's Duty Planner Standard Service gives written advice from a planning officer on simple homeowner projects, and it covers window replacement, including properties within a conservation area. For a New Cross renovation that includes new windows, that written answer gives a planning officer's view on style and material before they are ordered. Windows made to measure for a sash box take weeks, so book the advice at the start of the design rather than at the end.
Does stripping and replastering a New Cross Victorian house bring in insulation rules?
It can. Lewisham's own inspectors check energy conservation as well as structure, and renovating a large part of an outside wall can require its insulation to be improved. In New Cross 43% of homes were built before 1919, with solid brick walls that need to dry outwards and inwards. Insulation and plaster that let moisture escape are chosen at design stage and agreed with the inspector, rather than decided on the day the old plaster comes off.
Does taking out the extra showers and WCs in a former New Cross shared house need building control?
The new bathrooms that replace them do. Lewisham says an inspection is needed where a WC or bath is installed or its position is altered, and its fees chart has a line for installation of a new bathroom. Removing a spare shower room is mostly a matter of capping the supplies and the waste properly at the stack. The family bathroom and any en-suite that go in their place are notified and inspected before the floors and boxing are closed.
