Glazed and glass-box rear extensions in Herefordshire
Full-height glass, slim frames and big rooflights for the most open rear room. Rear extensions in Herefordshire: we cover 4 towns including Hereford, Leominster and Ross on Wye, with design, approvals and the build under one contract.
Glass-led rear extensions in Hereford are planned around which way the garden faces, because that decides the glass specification. Red-brick terraces and 1930s semis make up much of Herefordshire. Many already have a small kitchen lean-to at the back, which a new rear extension usually replaces rather than adds to.

Do you need planning permission in Herefordshire?
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.
