Do you need planning permission for a bungalow rear extension in Sleaford?
Whether your bungalow rear extension in Sleaford 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.
England also has the larger home extension route: a single-storey rear extension of up to 6 metres on an attached house or 8 metres on a detached house, after prior approval from the council. The council notifies your neighbours and has 42 days to decide; the fee is £249 (£310 for applications made from 8 December 2026). The route is not available on designated land such as conservation areas.
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 Sleaford like to extend?
Red-brick terraces and semis are typical of Sleaford. Coal-mining legacy areas in parts of the East Midlands can need a Coal Authority check before foundations are designed.

We visit free of charge, measure up, check access, drainage and neighbours' extensions, and note what you want the room to do.
Options and costs
We draw layout options and price each one, so the budget shapes the design rather than surprising you later.

We take the design through the right planning route, then produce the construction drawings and engineer's calculations for building control.

We build to the approved drawings with regular updates, then hand over the building control completion certificate and any guarantees from suppliers.

FAQ
Bungalow rear extension questions in Sleaford
Do I need a party wall agreement?
In England, usually yes if the extension is on or near a shared boundary or the foundations are close to a neighbour's building. We serve the notices.
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.
How deep can I extend?
The same limits as a house: 3 or 4 metres in England, more with prior approval.
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.
