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

Putney: the houses and the planning rules.
Putney rises from the river to the Heath through streets of Victorian and Edwardian houses, with mansion flats near the bridge, larger houses on West Hill and around the Heath, and the Dover House garden estate to the west. It is a family district with good schools, and the houses are extended accordingly.
Side-return and rear extensions, loft conversions and full refurbishments are the everyday projects, and on the larger West Hill and Heath-side plots we see double-storey extensions and basements. Wandsworth's guidance is clear and the council decides quickly when the drawings are complete.
The Putney Embankment, West Putney and Dover House Estate conservation areas cover parts of the district; many streets are unrestricted.
London Borough of Wandsworth
Wandsworth decides applications and publishes a house extension design guide; outside the conservation areas permitted development covers many rear extensions and lofts.
Basements
The borough's basement policy requires a construction method statement and limits new basements to a single storey under part of the garden.
Dover House estate
The garden estate has Article 4 directions and guidance on windows, roofs and extensions.
Approvals for house extensions in Putney.
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 Putney: your questions.
Do I need planning permission for an extension in Putney?
Not always. Permitted development covers many single-storey rear extensions on houses, but the London Borough of Wandsworth 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 Putney do you cover?
All of Putney and SW15, including West Hill, Putney Hill, Lower Richmond Road, Deodar Road, Howards Lane, Ravenna Road, and the neighbouring districts. We are based in London and our teams work across central, north, north-west, west and south-west London.
