Homes in Dundee and Angus

In Scotland many families extend bungalows and semis, while tenement flats bring shared ownership of roofs and walls that needs agreeing early.

What does a double-storey extension involve?

Two-storey work has to sit comfortably with the house and the neighbours, so most of the design effort goes into the roofline, window positions and how the new first floor connects to the landing. We handle the planning application, the structural design and the building control process, then build, roof and finish both floors.

High specification	£3,400 to £3,850 per m²

Planning and building rules in Dundee and Angus

In Scotland the key step is the building warrant, which must be granted before work begins. Planning permission is decided separately by the council, and work on shared walls is handled under your title deeds rather than a party wall act.

Two-storey extensions in Scotland almost always need planning permission, and a building warrant must be granted before work starts.

What should Dundee and Angus homeowners check first?

Side extensions close to a boundary are often set back or stepped down so they do not create a terraced effect.
The first-floor link can mean moving a bathroom or reshaping the landing.
