Garden annexes in Fulham

From the first site visit to the final building control sign-off, we manage garden annexes in Fulham so you only have one company to deal with.

Covering Fulham

Fulham sits 4 miles south-west of London, with Chelsea 1 miles to the east and Putney 2 miles to the south-west.

Homes in London

Terraced houses dominate many London neighbourhoods, so most projects involve shared walls, narrow access and a party wall process. Conservation areas are widespread, and some boroughs have their own mansard and basement guidance.

What is included in a garden annexe in Fulham?

We design annexes as permanent buildings with proper foundations, insulation and services, and we prepare the planning case showing how the annexe will be used as part of the main home. Connections for water, drainage and power are planned from the start.

Do you need permission for a garden annexe in Fulham?

In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.

A self-contained annexe used for sleeping and living normally needs planning permission in England. Permitted development for outbuildings does not cover living accommodation.

What should Fulham homeowners check first?

  • A level threshold and wider doors make the annexe suitable for later life.
  • Council tax treatment depends on who lives there; check with your council.
