Loft and garage conversions in East Kilbride
East Kilbride is mostly post-war houses, planned in neighbourhoods. It's a different starting point from a Victorian suburb. Roofs are often lower or trussed, so a loft isn't always the obvious answer, and a garage or garden room can make more sense.
We don't build anything. We pass your enquiry to one independent firm working in East Kilbride, who visits and quotes you. It's free to ask and you can say no.
How the town was built
East Kilbride was designated Scotland's first new town on 6 May 1947, according to Wikipedia's account of the town. The original neighbourhoods were The Murray, Calderwood, Westwood, Greenhills and St Leonards, each planned with its own shops and schools. Later came lower-density private housing in Stewartfield, Lindsayfield, Gardenhall and Mossneuk, and Jackton, laid out mainly in cul-de-sacs.
Age varies more than you'd expect. Calderwood was started in the early 1950s, while most of Greenhills dates from the early 1970s to early 1980s. New homes are still arriving at Jackton, including four and five-bedroom houses approved in 2019. Those are Wikipedia's dates, so treat them as a guide. Your house's own papers are better evidence.
Across South Lanarkshire, 82% of dwellings were built after 1945, and 72% are houses, according to the Scottish House Condition Survey tables for 2022 to 2024. That's a council-wide figure, and it takes in a lot more than this one town. There's no smaller published breakdown we could find.
Matching the project to the house
| If you have | Think about | Watch out for |
|---|---|---|
| A house from the early New Town years | Whether there's enough height for a dormer | A low pitch, and whether a stair will fit |
| A house from the 1970s or 1980s | A close look in the loft, then a garage or extension as the alternative | Trussed roofs mean new steel and a higher price |
| A newer estate home with an integral garage | A garage conversion | Conditions about parking in the estate's planning permission |
| A cul-de-sac house with a short rear garden | A rooflight conversion, or a garden room if the plot allows | The 10-metre rule for permitted development dormers |
| A home in the Village | Talking to the planners first | The conservation area removes the usual rights |
In a cul-de-sac the road often curves past the side of a house. That matters, because a dormer on a roof slope fronting a road can't be permitted development under Class 1D. Corner plots catch people out. Look at your own plot with that in mind.
The Village conservation area
South Lanarkshire has 30 conservation areas, and East Kilbride Village is the one in this town. The council publishes a map for each, so you can check your boundary. Inside it, there's no permitted development for a roof enlargement, and the limit for a garden building drops to 8 m². We didn't see an Article 4 Direction mentioned on the pages we read, but ask the council to confirm.
South Lanarkshire Council
- Warrants: the council's building warrants page says eBuilding Standards is the standard way to apply, and the fee calculator is on the same portal.
- Building standards phone: 0303 123 1015, from the Scottish Government's contact list. That list dates from February 2019, so check it if you can't get through.
- Planning: start with do I need planning permission? To ask a question, the team uses web forms. We didn't find a direct email or phone number for planning on those pages.
- Design guidance: the council's householder guidance wouldn't open when we checked. Ask the planning team what applies to dormers, or have your designer check.
What it costs
For a dormer, you're looking at £33,000 to £56,000 going by MyJobQuote's Glasgow figures, and for a garage conversion, about £14,500 on average across the UK. A single-storey extension of 20 to 30 m² is put at £44,000 to £60,000 nationally by MyJobQuote.
Sources: MyJobQuote Glasgow loft guide (9 October 2026); MyJobQuote garage guide (9 July 2026); MyJobQuote extension guide (19 October 2026). We found no figure just for East Kilbride.
A trussed roof tends to push the loft price up. A single-storey extension may be worth comparing if you've got the garden and you'd like more space downstairs anyway.

All of the G74 and G75 postcode districts: The Murray, Calderwood, Westwood, Greenhills, St Leonards, Stewartfield, Lindsayfield, Gardenhall, Mossneuk and Jackton, along with Nerston, Kittochside, Auldhouse and the Village. If you're in another part of South Lanarkshire, such as Hamilton or Blantyre, send your postcode anyway. We'll say if we can't find a firm.

Common questions
Are there special New Town rules on what I can build?
We found no published New Town rule that applies across the town, so we won't claim one. Individual homes can still have restrictions in the title deeds or in a past planning permission. Have your solicitor check the deeds, and ask the planning team about the planning history.
I've got a modern house with a trussed roof. Is that a problem?
It's a cost issue more than a dead end. The truss timbers hold the roof up, so they have to be replaced with a new structure, usually including steel. An engineer has to design it. MyJobQuote says this costs more than converting a traditional roof.
Who can give me free planning advice?
South Lanarkshire's planning page recommends Planning Aid Scotland for free, impartial advice. The council's planning team can also tell you whether permission is needed.
