Towns in Edinburgh and the Lothians
What we take care of
- Inspection bookings throughout the build
- Structural calculations for beams, lintels and foundations
- Energy and glazing checks, including whole-house calculations if needed
- Building regulations drawings and written specification
- Completion certificate on sign-off
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.
Working in Edinburgh and the Lothians
Towns we cover in Edinburgh and the Lothians include Edinburgh, Livingston, Musselburgh, Bathgate, Bonnyrigg, Penicuik, Broxburn. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
Do I need planning permission in Edinburgh and the Lothians?
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.
In a conservation area or national scenic area the householder permitted development rights are more limited, listed homes need listed building consent, and if rights have been removed by a condition or direction, any extension needs an application.
Scotland has no Party Wall Act. Where work affects a shared wall or a neighbour's land, we agree access, protection and making good with your neighbour in writing before work starts.
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.
