Glazed rear extension in Perth
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 Perth and the surrounding area, with one contract from the first survey to building control sign-off.
Perth sits in Perth and Kinross, with postcode districts including PH1 and PH2. Glass-led rear extensions in Perth are planned around which way the garden faces, because that decides the glass specification.

How much does a glazed rear extension cost in Perth?
For Perth we work from the Scotland rate: £2,660–£4,560 per square metre of new floor, including VAT, standard specification. Prices in Scotland sit a little below our West Midlands baseline; building warrant fees and drawings are budgeted separately.
| Size | Guide price inc VAT |
|---|---|
| 3 m wide × 4 m deep (12 m²) | £32,000–£54,500 |
| 4 m wide × 6 m deep (24 m²) | £64,000–£109,500 |
These are guide ranges; the written quote after the survey is the figure that counts.
Do you need planning permission for a glazed rear extension in Perth?
The planning route for a glazed rear extension in Perth is set by Scotland's householder rules and your council.
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. 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 Perth like to extend?
Perth has sandstone tenements, terraced houses and villas closer in, with post-war semis and newer estates further out. Tenement and other flats need planning permission for an extension, and every project needs a building warrant before work starts.

FAQ
Glazed rear extension questions in Perth
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.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Is a glass box a conservatory?
No. It is built to Building Regulations as part of the house, with insulated floor and roof, so it is usable all year.
Can you match the brick or stone on my Perth house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
How much does a glazed rear extension cost in Perth?
As a guide, £2,660–£4,560 per square metre including VAT for a standard specification. For example, 3 m wide × 4 m deep (12 m²): about £32,000–£54,500 at that rate. Your written price follows the survey.
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.
