Planning rules that apply in Westhill
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 Westhill 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.
Applications are decided by your council as planning authority.
Included in a typical project
- Structure, roof, insulation and finish
- Layout options: two-storey, over-garage or ground floor
- En-suite drainage and ventilation design
- Fire safety: escape windows and smoke alarms to building regulations
- Planning drawings and application
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.

Your questions about a bedroom extension in Westhill
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Westhill, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Westhill?
Yes. We cover Westhill and the surrounding parts of Aberdeen and Aberdeenshire. Site visits are free and there is no obligation.
Who do I contract with for a bedroom extension in Westhill?
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.
Can I add a ground-floor bedroom for a relative?
Yes. A ground-floor bedroom with an accessible shower room is a common request. If it will be lived in as a self-contained home, planning treats it differently, so tell us how it will be used.
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.
