House Extensions in Regent's Park.
An extension is the surest way to get the open-plan kitchen and dining room most families want, and the houses in Regent's 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 London Borough of Camden and the City of Westminster 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.

Regent's Park: the houses and the planning rules.
The terraces around Regent's Park are among the most protected houses in Britain: John Nash's stucco palaces on the Outer Circle are Grade I listed and held on Crown Estate leases, with the Camden side of the park administered by Camden and the Westminster side by Westminster. Behind them, Primrose Hill and the streets towards Camden Town are Victorian and largely within conservation areas.
Several of our most demanding projects are here: three vaults under a Grade I listed house enlarged into a habitable basement floor, a loft opened into a roof terrace with a bespoke glass skylight, and bathrooms and bedrooms refurbished under listed building consent. Working in these houses means drawings first, consent second and building third.
The Regent's Park Conservation Area covers the whole district, and the Nash terraces are Grade I listed.
Two planning authorities
Camden covers the north and east of the park, Westminster the south and west. Both apply conservation-area policies and both consult Historic England on Grade I and II* proposals.
Listed building consent
Internal alterations to the Nash terraces and villas need listed building consent. Heritage statements, careful detailing and reversible interventions are expected.
Crown Estate leases
Many terraces are on Crown Estate leases with their own approval process, which runs alongside the council's.
Approvals for house extensions in Regent's 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.
Camden covers the north and east of the park, Westminster the south and west. Both apply conservation-area policies and both consult Historic England on Grade I and II* proposals.

House Extensions in Regent's Park: your questions.
Do I need planning permission for an extension in Regent's Park?
Not always. Permitted development covers many single-storey rear extensions on houses, but the London Borough of Camden and the City of Westminster 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 Regent's Park do you cover?
All of Regent's Park and NW1, including Outer Circle, Chester Terrace, Cumberland Terrace, Park Village, Albany Street, Gloucester Gate, and the neighbouring districts. We are based in London and our teams work across central, north, north-west, west and south-west London.
