Approvals for an extension in Dursley
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
In England a single-storey side extension can be permitted development if it is no more than 4 m high and no wider than half the width of the original house. Two-storey side extensions, and any side extension on designated land such as a conservation area, need a householder planning application.
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).
Covering Dursley and nearby
Our survey diary covers Dursley, including GL11. We also work in nearby Stroud (8 miles), Thornbury (10 miles), Yate (11 miles), Gloucester (13 miles), Mangotsfield (15 miles). Ross-on-Wye, in Herefordshire, is roughly 18 miles from Dursley and also on our list.
Choosing the right extension in Dursley
In the South West, local stone, render and brick vary from town to town, so matching materials is a big part of designing an extension that looks right.
Depending on the plot, orangery extensions and single-storey rear extensions are often the strongest options, with pitched roof extensions worth considering where there is room.
