Edinburgh and the Lothians
Glazed and glass-box rear extensions in Edinburgh and the Lothians
Full-height glass, slim frames and big rooflights for the most open rear room. We design and build rear extensions across Edinburgh and the Lothians, from Edinburgh and Livingston to Musselburgh, covering single-storey kitchen extensions, two-storey additions, side returns and wraparounds.
A wide sliding door with one long rooflight, rather than a fully glazed roof, keeps a glass-led extension usable in summer. Edinburgh and the Lothians 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.

In Edinburgh and the Lothians, our guide for a glazed rear extension is £2,660–£4,560 per square metre including VAT for a standard specification. Prices in Scotland sit a little below our West Midlands baseline; building warrant fees and drawings are budgeted separately.

Ground conditions, glazing, the roof and how far the house is opened up move the final figure within the range.
Do you need planning permission in Edinburgh and the Lothians?
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.
Insulation and glazing follow Section 6 of the Scottish Technical Handbook; the building warrant drawings show how the extension meets it.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent.
