What does a garden annexe involve?

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.

How is a garden annexe approved in Falmouth?

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.

What should I think about before starting?

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.
