Working in Cupar
Postcode districts we cover around Cupar include KY15. Nearby, we also take on projects in Glenrothes (9 miles), St Andrews (10 miles), Kirkcaldy (13 miles), Dunfermline (22 miles).

Included in a typical project
- Whole-house energy calculations where needed
- Drainage details for frameless roofs
- Steel or glass beams and slim-frame glazing
- Design with specialist glazing input
- Solar-control and low-energy glass specification
- Planning drawings that show the glass detail
Solar gain is the risk. We specify solar-control glass, plan for opening vents or sliding panels, and avoid fully glazed roofs on south-facing extensions unless shading is included.
Do I need planning permission in Cupar?
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.
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.
Scotland has no Party Wall Act. Where work affects a shared wall or a neighbour's land, we agree access, protection and making good with your neighbour in writing before work starts.
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 glass extensions
Will my neighbours in Cupar 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.
Who do I contract with for a glass extension in Cupar?
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 you cover all of Cupar?
Yes. We cover Cupar and the surrounding parts of Fife. Site visits are free and there is no obligation.
How much does a glass extension cost?
Our guide range is about £2,940 to £5,680 per m² including VAT, because structural glass is made to order. A 12 m² standard-spec glass extension is typically £41,000 to £52,000 in Cupar.
Are glass extensions cold in winter?
Modern double or triple glazing with warm-edge spacers and underfloor heating keeps them comfortable. They are not as warm as a solid room, and we explain the trade-off honestly.
