Two-storey rear extensions in Fife
A larger kitchen downstairs and an extra bedroom or bathroom upstairs, under one roof. Across Fife we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Dunfermline, Kirkcaldy and Glenrothes.

Two-storey rear extensions suit semi-detached houses in Dunfermline best, where the extra bedroom matters as much as the bigger kitchen. Post-war semis and terraces are common around Fife, and many have room for a single-storey rear extension within Class 1A limits.
How much does a two-storey rear extension cost in Fife?
A two-storey rear extension in Fife is priced at £1,710–£2,560 per square metre including VAT as a guide, before kitchen fit-out and fees. Prices in Scotland sit a little below our West Midlands baseline; building warrant fees and drawings are budgeted separately.
| Size | Guide price inc VAT |
|---|---|
| 3 m × 5 m footprint, two floors (30 m²) | £51,500–£77,000 |
| 4 m × 6 m footprint, two floors (48 m²) | £82,000–£123,000 |
We put a fixed price in writing once the design is agreed, and explain any provisional sums such as foundations.
Do you need planning permission in Fife?
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.

FAQ
Questions people ask
Does a two-storey rear extension need planning permission?
Almost always. England and Northern Ireland allow 3 metres without an application only if at least 7 metres remains to the rear boundary; Wales and Scotland are similar or stricter.
Is two-storey cheaper per square metre than single-storey?
Usually yes, because the foundations and roof are shared across twice the floor area. The total cost is higher.
Can I add an en-suite upstairs?
Yes. We plan the soil pipe route early so the bathroom sits where drainage works without boxing through the room below.
Do you cover all of Fife?
We cover 7 towns and districts in Fife, including Dunfermline, Kirkcaldy and Glenrothes.
