Full-height glass, slim frames and big rooflights for the most open rear room. Rear extensions in West Yorkshire: we cover 38 towns including Leeds, Bradford and Huddersfield, with design, approvals and the build under one contract.

Highly glazed rear extension with full-height sliding glass doors, a glass box corner and a walk-on rooflight

If your garden in Leeds faces south, expect us to talk about overhangs and solar-control glass before frame colours. Stone terraces and brick semis are typical of West Yorkshire. Matching sandstone or gritstone on a terrace is one of the biggest cost variables, and reclaimed stone is often the best match.

Do you need planning permission in West Yorkshire?

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.

FAQ

Questions people ask

Will a glass extension be too hot?

Not if it is designed for its orientation, with solar-control glass, shading and ventilation.

Is there a limit on how much glass I can have?

In England the simple rule is 25% of the floor area plus openings removed; more is allowed with a calculation showing the house still meets Part L.

Sliding or bifold doors?

Sliders give bigger panes and slimmer sightlines; bifolds open the whole width. Our guide compares them.

Do you cover all of West Yorkshire?

Vetted building teams working under contract to us; your contract is with S&K Property Investments and Improvement Ltd.
