House Refurbishment St John's Wood

House refurbishment in St John's Wood is a small but distinct kind of job. Only 10% of homes on the VOA list here are houses, split evenly between terraces and semi-detached or detached houses, so a whole house to renew is the exception in a district of flats. Where one comes up, it may be a detached villa or a period terrace, and if it sits inside the St John's Wood Conservation Area its outside is controlled too. The work is renewing its services, plaster, joinery and roof without re-planning the rooms.

For St John's Wood, 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 St John's Wood: we renew the wiring, pipework, heating, plaster, floors and joinery of the whole house under one contract, and a registered electrician certifies the rewire.

Which St John's Wood houses come up for a full refurbishment

The houses here are few, and a refurbishment of an older one starts from original fabric. Of the homes in St John's Wood, 5% are terraced houses and 5% are semi-detached or detached, against 90% flats. Across the whole stock, 23% was built before 1919 and 31% between 1919 and 1939, in a district of interwar mansion blocks, later flats and a few detached villas. The brief might be a house bought after decades in one family's hands.

That profile tells you what to price for. A Victorian villa or terrace in St John's Wood can carry lath and plaster ceilings, lime render and plaster, timber suspended ground floors and lead or iron pipework in the voids. An interwar house may have early cavity walls, rubber-sheathed cable runs and a boiler added into a space never meant for one. We open up ceilings, floors and the roof void in the first week so the rewire, replumb and plastering are priced on what is really there.

Housing in St John's Wood

St John's Wood has around 8,840 homes on the Council Tax list: 46% post-war, 31% interwar and 23% predate 1919, with 90% flats and 10% houses. Where most homes are flats, a whole house in St John's Wood is refurbished as one building, roof down.

Conservation area rules on windows, doors and roofs in St John's Wood

Assume the outside of the house is controlled before you order a single window. The St John's Wood Conservation Area was designated in 1967 and extended in 1979 and 2007. In a Westminster conservation area you need planning permission for demolition and for some alterations that would not need permission elsewhere. Westminster has also removed permitted development rights in eight of its conservation areas, so ask the council which rules cover your street before the scope is fixed.

For a house refurbishment in St John's Wood the practical result is repair before replacement. Timber sashes are overhauled, re-corded and draught-proofed rather than swapped for new units, front doors and fanlights are repaired in the same pattern, and roof coverings, parapets and chimney stacks are made good in matching materials as the survey requires. Where a listed building or an unlisted building of merit is involved, your designer sets the consent route and we build to it.

Hours, scaffolding and the street outside a St John's Wood house

Westminster's normal hours for noisy building work are Monday to Friday 8am to 6pm and Saturday 8am to 1pm. Westminster asks for a Control of Pollution Act Section 61 application at least 28 days before works start if noisy construction has to go outside those hours. The strip-out, chasing for the rewire and breaking out of old screeds are therefore all planned inside them. Quieter work such as decoration can fill the rest of the day.

Scaffolding for a roof or chimney repair needs a temporary structure licence from Westminster before it goes on the pavement, and the footway must stay at least 1.5m wide around the works. A skip on the road needs its own highway permission too. Under the Code of Construction Practice, a small Level 4 project follows the Code's principles with no formal approval, monitoring or fees. We set out the licence dates, skip days and delivery windows in the programme so the neighbours know what to expect.

Running a St John's Wood house refurbishment in the right order

The order is strip, first fix, plaster, second fix and finish, and it only changes if you are living in the house. An empty St John's Wood house can be stripped floor by floor in one pass, with the electrician and plumber running first fix through open walls and floors together. If you stay in, we phase it: one floor is closed off and finished while you live on another, and water and power are kept on at the end of every day.

Building control follows the same sequence. Westminster runs its own District Surveyors Building Control Service and must be told the start date at least 2 days before work begins. Its completion certificate is issued only once fees are paid and the electrical and gas certificates are in. A registered electrician certifies the rewire and an engineer on the Gas Safe Register signs off the heating before the last coat of paint. Replacing windows or renewing a roof covering also brings in Part L thermal standards for those elements.

• Staircase repairs: treads, risers, strings, balusters and newel posts
• Roof, gutter and chimney-stack repairs coordinated as the survey requires
• Floorboard lifting, joist repairs and relaying on every floor

Trusted House Refurbishment in St John's Wood

A whole house is a longer job than a flat, and it needs one person holding the sequence from opening up to handover. Our founder has spent decades on the tools, and one site lead runs the house from strip-out to the snag list. We give you a written programme that shows the building control stages, the scaffold and skip dates and the certificates each trade must supply. A structural engineer is brought in only where the survey finds a floor or wall that needs one.
