Home Renovation, Listed Building Refurbishment and Design and Build in Kensington W8
Kensington is a district of grand houses that are mostly no longer houses. The stucco-fronted terraces around Kensington Square, Phillimore Gardens and Victoria Road were built for single families with staff, and a great many were divided into flats and maisonettes long ago. Behind them sit the mansion blocks along Kensington Church Street and Campden Hill Road, and the mews that once served the larger properties. What survives intact as a whole house is now the exception rather than the rule, and it is priced accordingly.
That inheritance decides what building work in W8 consists of. There is very little extending here — the plots are tight, the elevations are protected, and the rear of a townhouse is often as visible from a garden square as the front is from the street. What there is instead is renovation: taking a building that has been altered repeatedly across a century and a half and making it work as a single coherent home again. Whole-house refurbishment, lateral apartments formed from two flats, and the careful repair of interiors that have been stripped and re-fitted more than once.
The other thing that defines W8 is the number of separate permissions a project needs. The council publishes its Article 4 directions street by street and number by number, with dates running back to 1969, and some addresses carry three or four overlapping directions at once. Add listed building consent where the building is listed, planning permission where the work is external, and a licence to alter from the freeholder where the property is leasehold — and a Kensington project is running four consent processes in parallel before anyone lifts a tool.
Design And Build works throughout W8 on home renovation, listed building refurbishment and flat refurbishment. Architecture, interior design, structural engineering, party wall surveying and construction are all delivered by people this company employs, under one contract.

Home Renovation in Kensington W8
Home renovation of a Kensington townhouse
A W8 townhouse has usually been through several lives. Built as a single dwelling, divided at some point into flats, occasionally reunited since, and re-fitted by each owner in turn. What a full renovation confronts is not one building but the accumulated decisions of five or six of them — services routed wherever a previous contractor found space, partitions crossing original openings, and a plan that no longer corresponds to how anyone lives.
Work of this kind begins with removal rather than addition. Only once the later layers are off can the original structure be read properly, and only then can the services, the insulation appropriate to solid brickwork, and the layout be resolved together rather than in sequence.
Home renovation behind a protected elevation
The constraint that shapes almost every W8 scheme is that the outside of the building is not yours to change freely. Stucco, windows, front doors, railings, roof coverings and boundary treatments are precisely what the council’s heritage controls exist to hold in place, and in much of Kensington the relevant permitted development rights have been withdrawn.
Inside is a different matter, unless the building is listed. Where the elevation is protected but the interior is not, a great deal is achievable: reorganising a plan, opening a ground floor, moving services, rebuilding kitchens and bathrooms. The design discipline is to take the freedom where it exists and to treat the frontage as a separate, careful conversation.
Home renovation and interior design as one appointment
Selecting finishes after the building work is complete produces a house that reads as a sequence of separate decisions. We bring interior design into the process while the layout is still open, so that wall positions, ceiling heights, joinery, lighting and floor specification are settled as one set of choices.
On a period property this also determines what is worth keeping. Cornice runs can be matched where a section has been lost, a sash repaired for less than it costs to replace, and original panelling reinstated rather than boarded over. Those are design decisions as much as building ones, and they are made better when the same team is responsible for both.
Listed Building Renovation and Refurbishment in W8
Listed building consent reaches inside the building
This is the distinction that catches owners out. Conservation area designation governs what the street sees. Listed building consent governs the whole building, inside and out. Moving a wall, replacing a staircase, altering original joinery or changing a fireplace all require consent where the property is listed, and that consent runs alongside planning permission rather than in place of it.
Whether a specific address is listed is a matter of record and takes minutes to establish on the national list. It is worth doing before any design work, because the answer determines the entire route — and because carrying out unauthorised work to a listed building is a criminal offence rather than a planning matter to be regularised later.
Listed building refurbishment: what is usually possible
A great deal, handled properly. Consent is granted regularly for internal reordering that respects the surviving plan, for services upgraded discreetly, for thermal improvement to walls and windows where the method suits the fabric, and for the reinstatement of detail that has been lost. What fails is work designed first and justified afterwards.
Our architectural team establishes what is original and what is later accretion before proposing anything, because that distinction is what the case turns on. A heritage statement that identifies significance accurately, and shows the proposal working with it, is the difference between a consent and a refusal.
Listed building renovation and the basement question
Basements are the one route that is closed. RBKC controls subterranean development more tightly than any other authority in the country, and where a building is listed, excavation beneath it — including beneath the existing vaults — is not permitted at all. Elsewhere in the borough basement work is restricted rather than prohibited, but there is no permitted development route to one and every scheme is a full application supported by an impact assessment.
The practical consequence for a listed W8 property is that additional space has to be found within the existing envelope. That is a design problem rather than an engineering one, and it is usually solvable — but not by digging.
Flat Refurbishment and Licence to Alter in Kensington
Flat refurbishment in a W8 mansion block
The blocks along Kensington Church Street, Campden Hill Road and the main routes hold a large share of the borough’s housing, and refurbishing within one is a different exercise from working on a house. The building’s own condition affects your flat — roofs, rainwater goods, risers and communal heating all sit outside your demise and inside your problem. When you can get in, when you can make noise, how the hallways are protected and where the waste goes are all determined by the building, not by what suits the schedule.
Sound carrying between dwellings is what neighbours complain about, and it comes up on almost every job of this kind. Deal with it while the floors are lifted and the cost is marginal; come back to it later and it is anything but.
Licence to alter: the document pack your freeholder needs
Almost every flat in W8 is held on a long lease, and the lease governs what may be altered. Structural work, changes to services, and anything affecting the demise require the freeholder’s formal consent, granted through a licence to alter.
That consent is a legal process with its own requirements. The freeholder or managing agent will expect drawings, a specification, a method statement, evidence of contractor insurance, and confirmation of any statutory consents — reviewed by a surveyor acting for them, at your cost, to a timetable you do not set. Preparing that pack properly at the outset is the single most effective thing anyone can do to keep a Kensington flat project moving. Planning permission does not authorise you to begin work; neither does the licence on its own. We prepare and pursue both.
Flat refurbishment and lateral apartments
Joining two adjacent flats on the same floor is a central London answer to a central London problem: a building that cannot grow outward or upward can still be enlarged sideways. W8’s stock of subdivided townhouses and mansion blocks suits it, and it is among the most common substantial projects in the postcode.
Three things decide feasibility. The structure of the dividing wall, which may be load-bearing. The legal position, because the two leases have to be brought together into one and the freeholder has to agree to that. And the services, which need rationalising onto single supplies. Our structural engineers and the consent work run together, so the answer arrives before the design does.
Every W8 Street Has Its Own Article 4 Direction, Some Dating to 1969
The register runs street by street, number by number
Most councils withdraw permitted development rights across an area. Kensington and Chelsea does it property by property, and publishes the result. The register lists each affected street alphabetically with the specific house numbers, the direction number and the date it was served — odd runs and even runs separately, individual properties named where only one is caught.
In W8 that includes Kensington Square, Phillimore Gardens, Phillimore Place, Kensington Church Street, Kensington Court Place, Palace Gardens Terrace, Brunswick Gardens, Vicarage Gardens, Victoria Road, Scarsdale Villas, Essex Villas, Abingdon Road, Canning Place, Drayson Mews, Strathmore Gardens, Berkeley Gardens, Inverness Gardens, Uxbridge Street, Albert Place and Alma Terrace, among others.
Some addresses carry three or four directions at once
The register has been built up over more than fifty years, and the layers have not been consolidated. Canning Place appears three times, under directions served in 1969, 1987 and 1987. Inkerman Terrace appears four times, in 1971, 1978, 1978 and 1984. Vicarage Gardens appears three times, in 1974, 1984 and 1992. The earliest entry anywhere on the register is dated 19 May 1969.
So establishing your position is not a matter of finding your street and stopping. It means finding every direction that names your number and reading what each of them actually withdraws, because they are not identical and they do not supersede one another automatically. The council states plainly that the register is a summary and that the direction documents themselves are definitive.
Conservation area coverage across the borough is exceptionally high
Beyond the property-level directions, designation covers a very large proportion of Kensington and Chelsea — among the highest coverage of any authority in the country, alongside a concentration of listed buildings that includes significant numbers at Grade I and Grade II*. The practical effect is that a full application should be treated as the default in W8 rather than the exception, and the burden of proof runs the other way from most of London.
Four consents, running in parallel
A substantial Kensington project can require all of the following at once: planning permission for anything external; listed building consent where the building is listed, covering internal work as well; confirmation of what the Article 4 directions affecting that specific address have withdrawn; and the freeholder’s licence to alter where the property is leasehold.
They run in parallel, not in sequence, and each has its own timetable and its own decision-maker. Sequencing them properly is most of the project management on a W8 job, and getting it wrong is what turns a six-month programme into an eighteen-month one.
Area We Cover
Design and Build in Kensington: One Team, One Contract
Architectural design and structural engineering together
Our architects and structural engineers develop a scheme in the same office, which means the loads are resolved as the layout takes shape rather than after it is fixed. On a period building that matters more than usual, because what the structure will accept is frequently discovered rather than assumed, and a design settled before that discovery is a design that changes.
Interior design brought in while walls can still move
Design and build means the same firm is responsible for the drawing and the result. In practice its value shows in the details — where a service run is concealed, how a joinery line meets a cornice, whether a door swing works with the furniture that will actually be there. Those are decisions that fall between an architect and a contractor when the two are separately appointed, and they are where prime residential work is won or lost.
Why a construction company rather than four appointments
The alternative route in Kensington is well established: an architect, an interior designer, a structural engineer, a party wall surveyor and a main contractor, each separately appointed and coordinated by the client or a project manager acting for them. It works, and on the largest schemes it is the right structure.
On most W8 projects it opens a seam. A design priced higher than the budget anticipated, or a junction nobody took responsibility for between the drawing board and the scaffold, becomes an argument settled at the owner’s expense. A single construction company carrying design, engineering, consents and construction removes that — one contract, one price, one party accountable throughout. Where the Party Wall etc. Act 1996 applies, and in a subdivided W8 property that can mean notifying several neighbours simultaneously, our surveyors work out exactly who holds that right and serve on all of them.
