Do you need planning permission for a glazed rear extension in Greenock?
Whether your glazed rear extension in Greenock 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. At the first visit we measure what is there now and tell you which route fits: permitted development or a planning application, plus the building warrant.
What are homes in Greenock like to extend?
Post-war semis and terraces are common around Greenock, and many have room for a single-storey rear extension within Class 1A limits.

FAQ
Glazed rear extension questions in Greenock
Can you match the brick or stone on my Greenock house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Is the site visit in Greenock free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Will a glass extension be too hot?
Not if it is designed for its orientation, with solar-control glass, shading and ventilation.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
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.
How long does a rear extension take to build in Greenock?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
