Whole-house refurbishment in Knightsbridge
A full renovation of a Knightsbridge townhouse usually means stripping back tired services and starting again, with a complete rewire, new pipework and fresh plaster throughout. We reconfigure dated layouts, opening up cramped ground floors or reworking awkward upper storeys, and where that involves removing load-bearing walls we bring in engineer-sized steel and building control sign-off. The programme is planned floor by floor so the house comes together in a logical order.
These are period homes, so restoration sits alongside modernisation. We repair and reinstate cornicing, ceiling roses, panelled doors, sash windows and fireplaces where they are worth saving, matching profiles to the age of the house. In a listed or conservation-area property we work sympathetically with the original fabric, so the finished home in SW7 feels updated and comfortable yet still reads as the period house it has always been.
Housing in Knightsbridge
Of the 10,560 homes the valuation list records in Knightsbridge, 66% were built before 1919, 19% between the wars and 15% since 1945; 83% are flats and 17% are houses. Most homes here are flats, and a whole-flat refurbishment in Knightsbridge works to the lease: the freeholder's licence for alterations, agreed working hours and sound insulation between floors.
Shared services decide a Knightsbridge flat renovation
83% of homes in Knightsbridge are flats, and 19% of homes were built between 1919 and 1939, so a renovation here can happen inside a block whose heating, hot water and water supply are shared. A block of that period can run on a communal boiler plant, with risers passing through every flat. Replacing radiators or adding underfloor heating then means connecting to a system the freeholder controls, on the freeholder's terms, sometimes only when the plant is shut down. Ask the managing agent early for the system details and the drain-down arrangements, since they set dates the renovation has to meet.
The electricity supply is the other shared limit. The incoming supply to a flat in an older Knightsbridge block may have been sized for lighting and a few sockets, not for induction hobs, underfloor heating, steam ovens and air conditioning all at once. A renovation that adds those needs the load calculated before the design is fixed. If the supply has to be increased, that involves the network operator and the landlord's risers, and it takes time to arrange. We ask for the supply capacity at the first survey, so the design fits what the flat can actually draw.
One team managing your Knightsbridge project
The advantage of a single contractor on a large Knightsbridge refurbishment is sequencing. Structural steel, first-fix electrics and plumbing, plastering, joinery, kitchens, bathrooms and decoration all have to happen in the right order, and we hold that programme together so trades are not tripping over one another or redoing work. You have one point of contact rather than juggling separate firms across a complex, multi-room job.
Living in or letting a home in SW7 means the work has to be run cleanly and considerately, especially in a mansion block where managing agents and neighbours are close by. We protect finished areas, keep dust and disruption down, and coordinate any building management or freeholder requirements. From the first strip-out to the final snagging, the whole renovation is delivered by one accountable team with our founder's 30+ years on the tools.
- First and second fix sequenced around a realistic decorating date
- Snagging list agreed and worked through before handover
- Structural alterations and load-bearing wall removal

FAQ
Frequently Asked Questions about Home Renovation Knightsbridge
How much should a Knightsbridge homeowner set aside for home renovation?
A Knightsbridge homeowner should set aside the scoped figure for home renovation, typically within £40,000 to £150,000 or more (indicative), plus an allowance for the unseen. GS Renovation prices what the SW7 survey shows and names what could change once the structure of a purpose-built period home is opened. The cost of Royal Borough of Kensington and Chelsea or Westminster City Council building control inspection of any structural and drainage work belongs in the same budget.
Can you restore the period features while modernising my Knightsbridge house?
Yes. Restoring cornicing, ceiling roses, sash windows, panelling and fireplaces is a core part of how we renovate Knightsbridge townhouses, and we match new work to the original profiles. Alongside that we rewire, replumb, replaster and reconfigure the layout, and where the house is listed or in a conservation area we work sympathetically with the fabric so nothing of value is lost.
In what order do trades work on a Knightsbridge townhouse renovation?
Survey and strip-out come first, with an asbestos survey before anything is removed in a building from before 2000. Structural steel follows, then first-fix wiring and pipes, then plaster, then joinery and second fix, with decoration last. On a tall SW7 house the work usually moves from the top floor down, so dust from later stages never lands on finished rooms.
How does renovating a Knightsbridge flat differ from a house?
The lease sets much of the scope. Structural work, or relocating a kitchen or bathroom, generally needs written consent from the freeholder, and the soil stack normally serves the flats above and below as well. Block rules add working hours and lift bookings. Since VOA puts flats at 83% of dwellings in Knightsbridge, most projects begin with the licence to alter rather than the design.
What must building control be told about in a Knightsbridge refurbishment?
Anything structural under Part A, new circuits under Part P, extraction ducted outside from kitchens and bathrooms under Part F, drainage changes under Part H, and insulation where a wall, floor or roof is renovated under Part L. Redecoration, new plaster on sound walls and like-for-like fittings do not need notice. The electrician certifies their own work.
When should the heating system be chosen in a Knightsbridge renovation?
Before first fix, because pipe routes, the boiler or cylinder position and any underfloor heating decide what goes under the floorboards. In a flat, a new boiler flue through an external wall may need the freeholder's consent. Gas appliances are moved by a Gas Safe registered engineer, and their position affects the kitchen plan.
Do new windows in a Knightsbridge renovation still need separate planning permission?
For a flat, a window that looks different from the one it replaces needs permission today, because flats do not benefit from permitted development rights. The council has consulted on a Windows Local Development Order that would remove that separate application for non-listed homes throughout the borough. It is a consultation, so check whether the order has been made before relying on it. Either way, the council's Householders' Guide to windows states that building regulations apply to all replacement windows, so each one needs its compliance certificate.
Can an air conditioning unit go outside a Knightsbridge flat as part of a renovation?
Not without planning permission, and the freeholder's consent as well. Flats do not benefit from permitted development rights, so an external condenser on a flat is a planning matter, and conservation areas, which cover more than 73 per cent of the borough, make its visibility part of the assessment. The roof or a rear lightwell, out of sight from the street, are the positions most worth proposing. The freeholder decides what may be fixed to the building, and noise at neighbouring windows is assessed as part of the application.
Can secondary glazing be added to a Grade II* Knightsbridge house during a renovation?
Only with an application. Under the draft window Local Listed Building Consent Order, an application for listed building consent would remain necessary for similar works to Grade II* buildings and to buildings listed higher still. Secondary glazing on the inside, which leaves the original sashes and glass untouched, is the proposal that disturbs least. Allow for the consent period in the programme, since the glazing order waits for the decision.
