Side return extensions in Farnborough

Covering Farnborough

We work in Farnborough (GU11) and the places around it, including Camberley, Aldershot and Fleet.

Homes in the South East

Many South East homes are inter-war or post-war semis and detached houses with room for rear and side extensions, while historic town centres and villages bring conservation area and listed building controls.

What is included in a side return extension in Farnborough?

Side returns are small in area but heavy in detail: party walls, a glazed roof, and steelwork to take out the original back wall. We design the roof for light and drainage, agree the party wall process early, and keep the work tidy because access is often through the house.

Planning and building rules in Farnborough

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.

In England a single-storey rear extension can often go ahead under permitted development: up to 3 m deep on an attached house or 4 m on a detached one, no higher than 4 m, with eaves no higher than 3 m within 2 m of a boundary.

What can affect a side return extension?

Access is often through the house, so we plan deliveries and protect floors.
Many terraces sit in conservation areas, where side extensions need planning permission.
