Who a bedroom extension suits
- Multi-generational households
- Homeowners who want an en-suite master bedroom
- Growing families
New bedrooms on an upper floor need an escape window or a protected route to the outside under the building regulations. We design the window sizes and stair route to meet that from the outset.
Working in Bishopbriggs
Our survey diary covers Bishopbriggs, including G64. Nearby, we also take on projects in Kirkintilloch (3 miles), Bearsden (4 miles), Clydebank (7 miles), Dumbarton (14 miles).

Do I need planning permission in Bishopbriggs?
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.
The planning position for a specific Bishopbriggs address depends on its history and any designations, which is why we check it at the first visit.
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.

Common questions in Bishopbriggs
How long does a bedroom extension take to build in Bishopbriggs?
On site, typically 14 to 22 weeks once approvals are in place. Before that, allow 8–14 weeks design and approvals.
Will my neighbours in Bishopbriggs 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 I need building regulations approval in Bishopbriggs?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
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.
