House Extensions in Kenton.
An extension is the surest way to get the open-plan kitchen and dining room most families want, and the houses in Kenton 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 Harrow and London Borough of Brent 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.

Kenton: the houses and the planning rules.
Kenton is Metroland between Harrow and Wembley: long avenues of 1930s semis with tiled bays, hipped roofs and gardens deep enough for a full-width extension. The houses were well built and most have never been extended beyond a small kitchen addition, so the potential is considerable.
The typical Kenton project is a rear extension for an open-plan kitchen and family room, a hip-to-gable loft with a rear dormer for two more bedrooms, and a refurbishment of the rest of the house to match. Because there are no conservation areas, most of it is permitted development.
There are no conservation areas in Kenton; most streets are unrestricted.
Harrow and Brent
The borough boundary runs through Kenton; we check which council applies at the first visit. Both allow most rear extensions and lofts under permitted development.
Hip-to-gable lofts
The 50 cubic metre allowance for semi-detached houses usually covers a hip-to-gable conversion with a rear dormer, confirmed by a lawful development certificate.
Larger extensions
Double-storey rear extensions and side extensions that come within a metre of the boundary need a householder application.
Approvals for house extensions in Kenton.
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 Kenton: your questions.
Do I need planning permission for an extension in Kenton?
Not always. Permitted development covers many single-storey rear extensions on houses, but the London Borough of Harrow and London Borough of Brent 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 Kenton do you cover?
All of Kenton and HA3, including Kenton Road, Kenton Lane, Woodcock Hill, Draycott Avenue, Claremont Avenue, Streatfield Road, and the neighbouring districts. We are based in London and our teams work across central, north, north-west, west and south-west London.
