House Extensions in Holland Park.
An extension is the surest way to get the open-plan kitchen and dining room most families want, and the houses in Holland Park generally lend themselves to it: a side return to fill, a rear garden to build into, or on larger plots room for a full-width or double-storey addition.
We design the extension around how you will use it, not around the maximum footprint the rules allow. That means thinking about light, the level change to the garden, where the kitchen sits, how the old and new parts of the house meet and what happens to the rooms you already have. The structural engineering, party wall matters and building control inspections are all handled by us.
Approvals are checked on the first visit. Many single-storey rear extensions fall within permitted development, but the Royal Borough of Kensington and Chelsea applies tighter rules in conservation areas and to flats and listed buildings, so we confirm the route before any drawings are produced and then manage the application if one is needed.

Holland Park: the houses and the planning rules.
Holland Park has the largest houses in west London: detached Italianate villas on Holland Park itself and Addison Road, the studio houses built for Victorian painters on Melbury Road, and the stucco crescents of Norland. Plots are generous, gardens are deep and the planning authority protects both.
The work we see here is at the top end of the residential market: whole-house refurbishments with new services, basements under the larger villas, garden rooms and pool houses, and interiors finished to a standard that matches the architecture. Programmes run for months, and coordination with neighbours and the borough is part of the job.
The Norland, Holland Park and Royal Crescent conservation areas cover the district, and many of the villas are listed.
Royal Borough of Kensington and Chelsea
RBKC decides applications. Detached villas are assessed on their setting within the conservation area, and roof extensions and side additions are tightly controlled.
Basements
Large plots make basements possible but the borough's single-storey, half-garden limit still applies, with a full impact assessment.
Listed studio houses
The Melbury Road studio houses are listed; internal changes need listed building consent and specialist heritage input.
Approvals for house extensions in Holland Park.
Many single-storey rear extensions are permitted development within the 3 or 4 metre limits, or 6 and 8 metres under prior approval. Conservation areas, flats, listed buildings and larger schemes need a householder application, and every extension needs building regulations approval.

House Extensions in Holland Park: your questions.
Do I need planning permission for an extension in Holland Park?
Not always. Permitted development covers many single-storey rear extensions on houses, but the Royal Borough of Kensington and Chelsea removes those rights in some conservation areas, and flats and listed buildings always need an application. We confirm the route at the site visit.
How long does an extension take to build?
Ten to sixteen weeks on site for a single-storey extension once approvals are in place, plus the design and approval period beforehand. Glazing has the longest lead time, so we order it early.
Which parts of Holland Park do you cover?
