Will the council need to approve it?
In Scotland, householder permitted development rules (Class 1A for single-storey ground-floor extensions and Class 1B for extensions of more than one storey) allow some smaller extensions without a planning application, within limits on depth, height and distance from the boundary. Conservation areas and listed buildings are more restricted.
In a conservation area or national scenic area the householder permitted development rights are more limited, listed homes need listed building consent, and if rights have been removed by a condition or direction, any extension needs an application.
In Scotland a building warrant from the council is needed before work starts on almost any extension, and a completion certificate is issued when the work is accepted. Building standards are set in the Scottish technical handbooks.
Applications are decided by your council as planning authority.
Covering East Kilbride
Our survey diary covers East Kilbride, including G72, G74. We also work in nearby Cambuslang (3 miles), Blantyre (4 miles), Rutherglen (5 miles), Hamilton (6 miles).
For homes towards Renfrewshire and Inverclyde, Newton Mearns is around 6 miles away. Across Scotland, extensions follow Scottish planning and building standards, including the building warrant process, which we build into the programme from the start.

Questions people ask about flat roof extensions
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for East Kilbride, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do I need building regulations approval in East Kilbride?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Will my neighbours in East Kilbride be involved?
If a planning application is needed, the council notifies neighbours. Where work is close to a shared boundary, we agree access and protection with them in writing.
Are flat roof extensions cheaper?
Usually slightly, because there is less roof structure and no tiles. Our guide range is about £1,720 to £3,280 per m² including VAT.
Can I walk on a flat roof extension?
Only for maintenance unless it is designed as a terrace. A roof terrace or balcony needs planning permission and a different structure.
