Towns in Scottish Borders
Planning and approvals in Scottish Borders
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
Applications are decided by your council as planning authority.

What is included
- Completion certificate on sign-off
- Inspection bookings throughout the build
- Energy and glazing checks, including whole-house calculations if needed
- Building regulations drawings and written specification
Building regulations approval and planning permission are separate. A design can have planning consent and still need changes to meet the regulations, which is why we draw for both together.
Extensions in and around Scottish Borders
Towns we cover in Scottish Borders include Galashiels, Hawick, Peebles, Kelso. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.

Build and sign-off
The build is managed from start to finish, inspected at each stage and signed off on completion.
