Do I need planning permission in Musselburgh?
In Scotland, householder permitted development rules (Class 1A for single-storey ground-floor extensions and Class 1B for extensions of more than one storey) allow some smaller extensions without a planning application, within limits on depth, height and distance from the boundary. Conservation areas and listed buildings are more restricted. Separately, almost every extension needs a building warrant from the council before work starts.
The planning position for a specific Musselburgh 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.
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.

Your questions about a side return extension in Musselburgh
Do you cover all of Musselburgh?
Yes. We cover Musselburgh and the surrounding parts of Edinburgh and the Lothians. Site visits are free and there is no obligation.
How long does a side return extension take to build in Musselburgh?
On site, typically 10 to 14 weeks once approvals are in place. Before that, allow 6–12 weeks design and approvals.
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Musselburgh, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
How much does a side return extension cost?
Our guide range is about £2,060 to £3,720 per m² including VAT, so a typical 2 m × 5.5 m infill lands around £25,500 to £32,500 at standard spec in Musselburgh, more in London.
Can I combine a side return with a rear extension?
Yes. That combination is a wraparound extension, which adds the most space to a terraced house.
