Glazed rear extension in Giffnock
Full-height glass, slim frames and big rooflights for the most open rear room. We design, get the approvals for and build glazed and glass-box rear extensions in Giffnock and the surrounding area, with one contract from the first survey to building control sign-off.
Giffnock sits in Glasgow and the Clyde, with postcode districts including G46, G76 and G77. A wide sliding door with one long rooflight, rather than a fully glazed roof, keeps a glass-led extension usable in summer.

Do you need planning permission for a glazed rear extension in Giffnock?
Whether your glazed rear extension in Giffnock needs a planning application depends on its size, your house and any local restrictions.
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.
Insulation and glazing follow Section 6 of the Scottish Technical Handbook; the building warrant drawings show how the extension meets it.
Classes 1A and 1B do not apply in conservation areas, and listed buildings need listed building consent. We check your house's planning history and any conservation area before drawing, so the route is clear before you spend on plans.
What are homes in Giffnock like to extend?
Giffnock has sandstone villas and terraces, post-war semis and four-in-a-block flats. Flats need planning permission for an extension, and every project needs a building warrant before work starts.

Glazed rear extension questions in Giffnock
Do you handle building control in Giffnock?
Yes. We apply for the building warrant before work starts and submit the completion certificate at the end.

Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Sliding or bifold doors?
