Our survey diary covers Dunfermline, including KY11, KY12. The same team covers Kirkcaldy (12 miles), Glenrothes (14 miles), Cupar (22 miles), St Andrews (31 miles), all within easy reach.
For homes towards Edinburgh and the Lothians, Broxburn is around 10 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 rules that apply in Dunfermline
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.
Homes in conservation areas, national scenic areas and listed buildings have tighter rules, so we always check the property's status and planning history before design starts.
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.
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.
Applications are decided by your council as planning authority.

Your questions about a bedroom extension in Dunfermline
Will my neighbours in Dunfermline be involved?
If a planning application is needed, the council notifies neighbours. Where work is close to a shared boundary, we agree access and protection with them in writing.
Do you cover all of Dunfermline?
Yes. We cover Dunfermline and the surrounding parts of Fife. Site visits are free and there is no obligation.
How long does a bedroom extension take to build in Dunfermline?
On site, typically 14 to 22 weeks once approvals are in place. Before that, allow 8–14 weeks design and approvals.
Does an en-suite need a window?
No, but it needs mechanical extraction that meets the building regulations. We design the duct route at the drawing stage.
How much does a bedroom extension cost?
Our guide range is about £1,570 to £3,140 per m² including VAT. A bedroom with an en-suite of about 18 m² is typically £33,500 to £43,500 at standard spec, depending on whether it is part of a larger two-storey build.
