Do you need planning permission for a glazed rear extension in Guisborough?
Here is how the rules in England apply to a glazed rear extension in Guisborough.
English permitted development (Class A) allows a single-storey rear extension of 3 metres on a terraced or semi-detached house and 4 metres on a detached one, measured from the original house, with a maximum height of 4 metres and eaves of no more than 3 metres within 2 metres of a boundary.
New fabric must meet Approved Document L (2021 edition incorporating 2023 amendments): walls 0.18, roof 0.15 and floor 0.18 W/m²K, windows 1.4 W/m²K or Band B. Under the simple route, new windows, doors and rooflights should not exceed 25% of the extension floor area plus any openings removed; more glass is possible with a whole-house calculation.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always 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 Guisborough like to extend?
Terraces and semis are typical around Guisborough. On terraces a single-storey rear extension across the back yard is usually the practical choice; semis often have room for more.

FAQ
Glazed rear extension questions in Guisborough
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.
How much does a glazed rear extension cost in Guisborough?
As a guide, £2,520–£4,320 per square metre including VAT for a standard specification. For example, 3 m wide × 4 m deep (12 m²): about £30,000–£52,000 at that rate. Your written price follows the survey.
Sliding or bifold doors?
Sliders give bigger panes and slimmer sightlines; bifolds open the whole width. Our guide compares them.

Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.

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.
