Dunbar, Edinburgh and the Lothians
Two-storey rear extension in Dunbar
A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. We design, get the approvals for and build two-storey rear extensions in Dunbar and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Dunbar (EH42) as part of our Edinburgh and the Lothians work. Two-storey rear extensions suit semi-detached houses in Dunbar best, where the extra bedroom matters as much as the bigger kitchen.

Do you need planning permission for a two-storey rear extension in Dunbar?
Whether your two-storey rear extension in Dunbar needs a planning application depends on its size, your house and any local restrictions.
Scottish Class 1B rights for extensions of more than one storey need a 10 metre gap to every boundary, which few gardens have. Expect a planning application as well as a building warrant for a double-storey rear extension.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Dunbar like to extend?
Dunbar has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.

FAQ
Two-storey rear extension questions in Dunbar
How long does a rear extension take to build in Dunbar?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Is the site visit in Dunbar free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Can it be built on a terraced house?
Sometimes, but the upper floor is harder to get through planning on a terrace because of the effect on neighbours. A single-storey extension with a loft conversion is often an easier route.
Do I need a party wall agreement?
Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.
Do I need planning permission for a rear extension in Dunbar?
Many single-storey rear extensions are permitted development under Class 1A, but not in conservation areas; you always need a building warrant before work starts.
