Single-storey rear extensions in Dundee and Angus
Ground-floor space across the back of the house, usually for a kitchen, dining or family room. Across Dundee and Angus we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Dundee, Arbroath and Forfar.
A depth of 3 to 4 metres keeps many single-storey rear extensions in Dundee within permitted development, subject to the house's planning history. Post-war semis and terraces are common around Dundee and Angus, and many have room for a single-storey rear extension within Class 1A limits.

For Dundee and Angus we work from the Scotland rate: £1,800–£2,940 per square metre of new floor, including VAT, standard specification. Prices in Scotland sit a little below our West Midlands baseline; building warrant fees and drawings are budgeted separately.

Do you need planning permission in Dundee and Angus?
In Scotland a single-storey rear extension can be permitted development under Class 1A: eaves no higher than 3 metres and an overall height of 4 metres, and where any part is within 1 metre of a boundary it can project no more than 3 metres on a terraced house or 4 metres on other houses. The rights do not apply in conservation areas, and a building warrant is still needed before work starts.
Scotland has no larger-extension prior approval route; extensions beyond permitted development need a planning application.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent.

FAQ
Questions people ask
Is a flat roof or a pitched roof better?
A warm flat roof keeps the extension low under first-floor windows and suits a roof lantern; a pitched or lean-to roof gives a vaulted ceiling. Both last for decades when built properly.
Can I stay in the house during the build?
Usually yes. The noisiest, dustiest stage, removing the back wall, is kept to the final weeks and screened off. Most families set up a temporary kitchen elsewhere in the house.
Will the extension make the room behind it dark?
Not if it is designed well. Rooflights or a lantern over the old back room, and a wide opening into it, keep daylight reaching the middle of the house.

We cover 6 towns and districts in Dundee and Angus, including Dundee, Arbroath and Forfar.
