Falkirk, Forth Valley
Glazed rear extension in Falkirk
For homes in Falkirk, a glazed rear extension is often the simplest way to gain space without moving. Full-height glass, slim frames and big rooflights for the most open rear room. We take it from survey to completion certificate.
Falkirk sits in Forth Valley, with postcode districts including FK1, FK2, FK3 and FK5. 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 Falkirk?
Here is how the rules in Scotland apply to a glazed rear extension in Falkirk.
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 Falkirk like to extend?
Falkirk 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.

FAQ
Glazed rear extension questions in Falkirk
Can you match the brick or stone on my Falkirk house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
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.
Does glass need planning permission?
The same rules apply as any rear extension; glass does not change the depth or height limits.
Do I need a party wall agreement?
Scotland has no Party Wall Act; we agree access and protection with your neighbour in writing instead.
How long does a rear extension take to build in Falkirk?
Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.
