Glazed rear extension in Barking
For homes in Barking, 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.
Barking is covered from our Greater London round, including IG11, RM6, RM8 and RM9. Glass-led rear extensions in Barking 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 Barking?
Here is how the rules in England apply to a glazed rear extension in Barking.
In England a single-storey rear extension can often be built under permitted development: up to 3 metres beyond the original rear wall of an attached house, or 4 metres on a detached house, no higher than 4 metres, with eaves no higher than 3 metres if any part 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 Barking like to extend?
Barking is mostly 1930s semis, short terraces and post-war houses, so full-width single-storey and two-storey rear extensions are realistic on many plots. Some later estates had permitted development rights removed by condition, so we check the planning history first.

FAQ
Glazed rear extension questions in Barking
What postcode areas do you cover around Barking?
Including IG11, RM6, RM8, RM9 and RM10, and the surrounding Greater London area.
Can you match the brick or stone on my Barking house?
We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.
Does glass need planning permission?
The same rules apply as any rear extension; glass does not change the depth or height limits.
Can I live at home while the extension is built?
Usually yes. Most of the work is outside until the back wall is opened near the end, and that stage is screened off.

Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do I need planning permission for a rear extension in Barking?
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.
