Home Renovation Lewisham

GS Renovation carries out whole-house refurbishments across Lewisham, from the Victorian and Edwardian terraces of Catford and Forest Hill to flats in converted houses and post-war blocks. One team manages the rewiring, replumbing, replastering and structural work, so a dated period home becomes a warm, modern family house.

In Lewisham, 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 Lewisham: 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 Lewisham and bathroom renovation in Lewisham. With 60% of homes in Lewisham flats, the soil stack usually fixes where a bathroom can go, and the lease may need the freeholder's consent for either room.

Full refurbishment of Lewisham period homes

Many Lewisham terraces still carry decades of piecemeal work, tired wiring, cold single-glazed windows, damp in the closet wing and a warren of small rooms. We take the house back to a sound base, renew the electrics and plumbing, treat damp, insulate where we can, and replaster throughout. Working room by room, or clearing the whole house at once, we bring everything up to current standards under a single, coordinated programme.

Layouts designed for Victorian life rarely suit a modern family. We reconfigure the ground floor to open living space, relocate a bathroom that was tacked onto the back, and rethink how the closet wing is used. Where walls come out we bring in steel beams and building control, and where original features survive, cornicing, ceiling roses, cast-iron fireplaces and panelled doors, we restore and keep them, so the house feels modern without losing its Lewisham character.

Housing in Lewisham

Lewisham has around 133,910 homes on the Council Tax list: 45% post-war, 18% interwar and 34% predate 1919, with 60% flats and 40% houses. Since most homes here are flats, a whole-flat refurbishment in Lewisham works to the lease: the freeholder's licence for alterations, agreed working hours and sound insulation between floors.

Outside changes to Lewisham flats in conservation areas

Lewisham says flats or subdivided houses in conservation areas do not have permitted development rights and must seek planning permission for changes to the exterior. Six in ten Lewisham homes are flats. A whole-flat renovation in a converted period house can therefore meet this rule at the windows, the front door or a new extract vent through the front wall, even where the same change to a whole house would need no application. List every change that will show from outside before the programme is set in Lewisham, because a planning application sits in front of those items and cannot be rushed at the end.

Windows are often the outside change a renovation includes. Lewisham's Duty Planner Standard Service covers window replacement including within a conservation area, so written advice from a planning officer can settle the design before the joiner measures up. For a renovation across a whole Lewisham house the same logic holds: agree what the outside will look like first, then strip out, rewire, replumb and replaster inside while any application runs. Keeping the two tracks apart stops the finishing trades waiting on a window decision at the end of the job.

One team managing your Lewisham renovation

The risk on a big refurbishment is a string of separate trades who never quite join up. GS Renovation runs the whole job with one point of contact, sequencing the structural work first, then first-fix electrics and plumbing, plastering, and finally the kitchen, bathrooms, joinery and decoration. On a terraced street in SE6 or SE13 that also means managing access, deliveries and skips considerately, keeping the site tidy and your neighbours onside.

Because we hold the whole programme, decisions get made quickly and money is not wasted on trades waiting on each other. Notifiable work is covered: the new consumer unit and circuits are certified by a registered electrician under Part P, and any drainage changes are signed off by building control. Whether you are staying put through the works or renovating a newly bought home near Telegraph Hill before you move in, you get a clear schedule and one company answerable for the result.

• Full and partial rewiring, certified by a registered electrician under Part P
• Structural alterations and load-bearing wall removal
• First and second fix sequenced around a realistic decorating date
