Working in Cumbernauld
Across G65, G67, G68, we can visit, measure and advise. Nearby, we also take on projects in Airdrie (6 miles), Coatbridge (6 miles), Bellshill (9 miles), Motherwell (11 miles).
Just over the Dunbartonshire border, Kirkintilloch is about 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.
What is included
- Roof windows positioned for light and ventilation
- Vaulted ceilings or flat ceilings with storage above
- Lead or proprietary flashings to the main wall
- Roof design matched to the existing pitch and tiles
Matching tiles is harder than it sounds. We source reclaimed or closest-match tiles where the originals are no longer made and agree samples with you before ordering.
Do I need planning permission in Cumbernauld?
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. Separately, almost every extension needs a building warrant from the council before work starts.
Before any drawing is finalised we check whether the house is listed, in a conservation area or subject to an Article 4 direction.
Building close to a public sewer needs the agreement of Scottish Water, which we check during design.
Applications are decided by your council as planning authority.

Questions people ask about pitched roof extensions
Who do I contract with for a pitched roof extension in Cumbernauld?
Your contract is with S&K Property Investments and Improvement Ltd, which designs and manages the project and the build teams who carry it out.
Do I need building regulations approval in Cumbernauld?
Yes. Almost every extension needs it, whatever the planning route. In Scotland that means a building warrant before work starts.
Will my neighbours in Cumbernauld 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.
Is a pitched roof better than a flat roof?
Neither is better in all cases. Pitched roofs blend with traditional houses and shed water quickly; flat roofs give more headroom and suit modern designs and lanterns.
How much does a pitched roof extension cost?
Our guide range is about £1,810 to £3,430 per m² including VAT, a little more than a flat roof because of the roof structure and tiles.
