Port Glasgow, Glasgow and the Clyde
Glazed rear extension in Port Glasgow
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 Port Glasgow and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Port Glasgow (PA13, PA14 and PA15) as part of our Glasgow and the Clyde work. 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 Port Glasgow?
Whether your glazed rear extension in Port Glasgow needs a planning application depends on its size, your house and any local restrictions.
In Scotland a single-storey rear extension can be permitted development under Class 1A: eaves no higher than 3 metres and an overall height of 4 metres, and where any part is within 1 metre of a boundary it can project no more than 3 metres on a terraced house or 4 metres on other houses. The rights do not apply in conservation areas, and a building warrant is still needed before work starts.
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 Port Glasgow like to extend?
Post-war semis and terraces are common around Port Glasgow, and many have room for a single-storey rear extension within Class 1A limits.

FAQ
Glazed rear extension questions in Port Glasgow
Can you match the brick or stone on my Port Glasgow house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.
Will a glass extension be too hot?
Not if it is designed for its orientation, with solar-control glass, shading and ventilation.

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