Extensions in and around Aberdeen and Aberdeenshire
Towns we cover in Aberdeen and Aberdeenshire include Aberdeen, Peterhead, Inverurie, Stonehaven, Ellon, Westhill. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.
What is included
- Heating extended to the new rooms
- Structure, roof, insulation and finish
- Layout options: two-storey, over-garage or ground floor
- Fire safety: escape windows and smoke alarms to building regulations
- En-suite drainage and ventilation design
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.
Do I need planning permission in Aberdeen and Aberdeenshire?
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.
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.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
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.

Common questions in Aberdeen and Aberdeenshire
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Aberdeen and Aberdeenshire, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Will my neighbours in Aberdeen and Aberdeenshire 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.
How long does a bedroom extension take to build in Aberdeen and Aberdeenshire?
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.
Will a new bedroom need planning permission?
Upstairs additions usually do. Ground-floor rooms may fall within permitted development, depending on size and position.
