Glazed rear extension in Kingswinford
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 Kingswinford and the surrounding area, with one contract from the first survey to building control sign-off.
We cover Kingswinford (DY5, DY6 and DY8) as part of our West Midlands 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 Kingswinford?
Here is how the rules in England apply to a glazed rear extension in Kingswinford.
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 Kingswinford like to extend?
Kingswinford has a lot of post-war semis and estate houses with long gardens and side access, which makes rear extensions quicker to build.

FAQ
Glazed rear extension questions in Kingswinford
Do I need planning permission for a rear extension in Kingswinford?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
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 have a level threshold?
Yes, with a drainage channel outside the doors and the slab set to the patio level.
