Do you need planning permission for a glazed rear extension in Ware?
Whether your glazed rear extension in Ware needs a planning application depends on its size, your house and any local restrictions.
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 Ware like to extend?
Ware mixes Victorian terraces with 1930s semis, so both side returns and full-width kitchen extensions suit houses here.

Glazed rear extension questions in Ware
Can I get a price without a visit?
Our online guide-price tool gives a range in a couple of minutes. A written price needs a survey.

We source the closest match and show you samples before ordering; reclaimed materials are often the best match on older houses.

No. It is built to Building Regulations as part of the house, with insulated floor and roof, so it is usable all year.

Most single-storey rear extensions take 10 to 16 weeks on site and two-storey extensions 16 to 26 weeks, after design and approvals.
