Covering Bonnyrigg
Our survey diary covers Bonnyrigg, including EH18, EH19, EH22, EH24. The same team covers Musselburgh (5 miles), Penicuik (6 miles), Edinburgh (6 miles), Broxburn (15 miles), all within easy reach.
For homes towards Scottish Borders, Peebles is around 15 miles away. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
Will the council need to approve it?
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.
The planning position for a specific Bonnyrigg address depends on its history and any designations, which is why we check it at the first visit.
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.
Applications are decided by your council as planning authority.

Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
