Working in Musselburgh
Postcode districts we cover around Musselburgh include EH21. The same team covers Bonnyrigg (5 miles), Edinburgh (6 miles), Penicuik (10 miles), Broxburn (16 miles), all within easy reach.
Just over the Fife border, Kirkcaldy is about 13 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.
Planning and approvals 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.
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.
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.
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.

Questions people ask about timber frame extensions
Who do I contract with for a timber frame extension in Musselburgh?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Do I need building regulations approval in Musselburgh?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
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.
Is timber frame cheaper than brick?
It is similar overall. The frame can save time on site, but the cladding choice has a big effect on cost. Our guide range is about £1,720 to £3,330 per m² including VAT.
Does a timber frame extension need planning permission?
The same planning rules apply as for any extension. If the cladding looks different from the house, permitted development’s matching-materials condition may mean an application is needed.
