House Extensions in Richmond.
An extension is the surest way to get the open-plan kitchen and dining room most families want, and the houses in Richmond 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 Richmond upon Thames 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.

Richmond: the houses and the planning rules.
Richmond has Georgian houses around the Green and up the Hill, Victorian villas along the roads to the Park, and Edwardian streets between the station and Kew. The view from Richmond Hill is protected by Act of Parliament, and the conservation areas are among the most carefully managed in outer London.
Refurbishments here range from listed Georgian townhouses to Edwardian family houses that want a kitchen extension and a loft. The council's design guidance is detailed and its conservation officers are engaged, so the drawings and heritage statement are prepared to match.
The Richmond Town, Richmond Hill, Richmond Green and Kew Green conservation areas cover the centre and the riverside, and many houses are listed.

House Extensions in Richmond: your questions.
Do I need planning permission for an extension in Richmond?
Not always. Permitted development covers many single-storey rear extensions on houses, but the London Borough of Richmond upon Thames 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 Richmond do you cover?
All of Richmond and TW9 · TW10, including Richmond Hill, The Green, Kew Road, Sheen Road, Queens Road, Marlborough Road, and the neighbouring districts. We are based in London and our teams work across central, north, north-west, west and south-west London.
