Homes in the Scottish Borders

Housing in Scotland includes tenements in the cities, sandstone villas, inter-war and post-war semis and a large number of bungalows, which often suit dormer and upward extensions.

What is included in a garden annexe in the Scottish Borders?

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 the Scottish Borders?

In Scotland the key step is the building warrant, which must be granted before work begins. Planning permission is decided separately by the council, and work on shared walls is handled under your title deeds rather than a party wall act.

In Scotland an annexe needs planning permission and a building warrant before work starts.

What can affect a garden annexe?

The annexe normally has to remain part of the main household, not let as a separate home.
Council tax treatment depends on who lives there; check with your council.
