Do I need planning permission in Montrose?
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.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
Applications are decided by your council as planning authority.
Working in Montrose
Across DD10, we can visit, measure and advise. Neighbouring towns we cover include Arbroath (14 miles), Forfar (20 miles), Dundee (28 miles).
Just over the Aberdeen and Aberdeenshire border, Stonehaven is about 18 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.

Your questions about a side return extension in Montrose
Will my neighbours in Montrose 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 Montrose?
Yes. We cover Montrose and the surrounding parts of Angus and Dundee. Site visits are free and there is no obligation.
Do I need building regulations approval in Montrose?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Can I combine a side return with a rear extension?
Yes. That combination is a wraparound extension, which adds the most space to a terraced house.
Will the kitchen be darker?
Not if the roof is designed well. A glazed roof or a line of rooflights along the boundary usually makes the room brighter than before.
