Glazed rear extension in Chigwell
For homes in Chigwell, a glazed rear extension is often the simplest way to gain space without moving. Full-height glass, slim frames and big rooflights for the most open rear room. We take it from survey to completion certificate.
Chigwell and its postcode districts IG7, IG9 and IG10 are part of our Essex coverage. Glass-led rear extensions in Chigwell are planned around which way the garden faces, because that decides the glass specification.

Do you need planning permission for a glazed rear extension in Chigwell?
Whether your glazed rear extension in Chigwell needs a planning application depends on its size, your house and any local restrictions.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is 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. At the first visit we measure what is there now and tell you which route fits: permitted development, prior approval or a planning application.
What are homes in Chigwell like to extend?
Chigwell mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.
