Rear extensions for terraced houses in Ayrshire
Rear and side return extensions for terraces, with access through the house and two neighbours. Across Ayrshire we handle the whole rear extension: survey, drawings, the planning route, building control and the build. Towns we cover here include Kilmarnock, Ayr and Irvine.

Terraced streets make up much of the housing in parts of Ayrshire, and most rear extensions here go in without side access. Post-war semis and terraces are common around Ayrshire, and many have room for a single-storey rear extension within Class 1A limits.
How much does a terraced house rear extension cost in Ayrshire?
A terraced house rear extension in Ayrshire is priced at £1,950–£3,140 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 wide × 4.5 m deep (13.5 m²) | £26,500–£42,500 |
| 3 m wide × 6 m deep (18 m²) | £35,000–£56,500 |
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 Ayrshire?
Scottish householder permitted development (Class 1A) covers many single-storey rear extensions, with a 3 metre eaves limit, a 4 metre height limit and, within 1 metre of a boundary, a depth limit of 3 metres for terraced houses or 4 metres for others. Conservation areas are excluded, and you need a building warrant whatever the planning position.
There is no Party Wall Act in Scotland; neighbour matters are handled through the title deeds, common law and written agreement before work starts.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent.

FAQ
Questions people ask
Can you build without side access?
Yes. Materials come through the house in protected runs or over the roof by crane on tight sites.
Will my terrace be in a conservation area?
Many Victorian terraces are. Your council's map shows it; we check at the survey.
Can a terrace have a two-storey rear extension?
It is possible but harder to get through planning because of the effect on both neighbours.
Do you cover all of Ayrshire?
We cover 9 towns and districts in Ayrshire, including Kilmarnock, Ayr and Irvine.
Who builds the extension?
Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
