House Refurbishment Clapham

House refurbishment in Clapham is a smaller share of the work than the flats, because 28% of homes here are houses and 24% are terraced houses. The stock is old: 58% of all homes in Clapham were built before 1919. Refurbishing one of these houses means renewing wiring, pipes, heating, plaster, floors and sash windows on every floor without changing the plan, and doing it on a street where parking, skips and working hours are all controlled by Lambeth.

For Clapham, published UK figures put a three-bed house refurbishment at £43,530 to £110,350, and London houses usually cost more, with a London architect allowing £1,800 to £2,200 per square metre before VAT (Checkatrade and Bradley Van Der Straeten Architects, 2026). GS Renovation Ltd, a building contractor based in Potters Bar, does the work in Clapham: we renew the wiring, pipework, heating, plaster, floors and joinery of the whole house under one contract, and a registered electrician certifies the rewire.

The Clapham terraced house and the fabric it comes with

A Clapham house is most likely a Victorian or Edwardian terrace, since 24% of homes here are terraced houses and only 4% are semi-detached or detached. Built before 1919, a house like this has solid brick walls, suspended timber ground floors over a ventilated void, lath and plaster ceilings and a slate roof behind a parapet. Each of those elements ages differently, and a whole-house refurbishment is the one time you can look at all of them together, with the floors up and the walls bare.

We start with a room-by-room survey and write the schedule from it. It records which ceilings stay and are consolidated, which walls are hacked back and replastered in lime, and which joists need sistering where past plumbers notched them. It also says which sashes are overhauled rather than replaced. Roof, gutter and chimney-stack repairs are scheduled with the scaffold they need, so they are done once, at the start, before any new plaster goes on inside.

Housing in Clapham

Clapham has around 22,800 homes on the Council Tax list: 34% post-war, 6% interwar and 58% predate 1919, with 72% flats and 28% houses. Most homes here are flats, and where most homes in Clapham are flats, a whole house is refurbished as one building, with a single intake for the services and one roof to keep sound.

Windows, doors and roofs in Clapham's conservation areas

Before you replace windows, a front door or roof slates on a Clapham house, check whether it sits in a conservation area. Lambeth's Clapham conservation area (CA 01), first designated in 1968, is centred on Clapham Common, and Lambeth has 62 conservation areas covering approximately 30% of the borough. Inside one, the look of the front elevation matters. Lambeth says planning permission is required to demolish a building in a conservation area, so taking down more than internal fabric, such as an outbuilding or a boundary wall, is checked first.

Lambeth also lists the conservation areas with Article 4 Directions on external alterations. The list names places such as Albert Square, Hyde Farm and Stockwell Park, not the Clapham conservation area, but check your address before new windows are ordered. Either way it shapes the specification more than it stops the work: timber sashes repaired or copied in timber, slates matched, and chimney stacks rebuilt to the same profile. The owner or their designer makes any application, and we price and programme the joinery to the consented detail.

Order of works in a whole Clapham house

A Clapham house refurbishment runs in five stages: strip, first fix, plaster, second fix and finish. Strip-out takes off failed plaster, old wiring and redundant pipework and lifts the floors. First fix brings in the new cable runs, heating pipes and waste routes while everything is open. Plastering closes the walls and ceilings. Second fix puts in the sockets, radiators, sanitaryware and joinery, and finishing covers floors and decoration. Doing it in this order means no finished room is opened twice.

The rewire is certified by a registered electrician, and gas work on a new boiler is done by an engineer on the Gas Safe Register. Where you renew a thermal element such as a roof or a ground floor, Part L asks for insulation to be upgraded as part of that work. For notifiable work Lambeth takes either a building notice or a full plans application, and after a building notice you are able to commence works 48 hours after the council receives it.

Skips, parking and working hours on a Clapham street

Lambeth allows building work Monday to Friday 8.00am to 6.00pm and Saturday 8.00am to 1.00pm, with none on Sundays or bank holidays, and a whole-house job in Clapham runs to those hours. Strip-out is the loudest and dirtiest week, so neighbours on both party walls hear about the date in advance. On a terraced street there is no side access, and every bag of old plaster leaves through the front door and hall, which we protect before the first wall is opened.

A skip on the road needs a licence, and in Lambeth only the skip company can apply for it. The parking bay it stands in needs a standard suspension, which takes 10 or more working days' notice. Scaffold for chimney or roof repairs needs a Lambeth highways licence if it stands on the pavement. If your Clapham house has a front garden deep enough, a skip there needs no highway licence, and we look at that option at the survey.
