What works best for Kenilworth houses?
The West Midlands has a large stock of 1930s and post-war semi-detached houses, which are well suited to rear, side and over-garage extensions, plus Victorian terraces in the older inner areas.
The types we would usually look at first for a home in Kenilworth are kitchen extensions, double-storey extensions and single-storey rear extensions, depending on the garden and how the house is laid out.
Covering Kenilworth and nearby
Our survey diary covers Kenilworth, including CV8. The same team covers Warwick (5 miles), Leamington Spa (5 miles), Bedworth (10 miles), Stratford-upon-Avon (12 miles), Nuneaton (13 miles), all within easy reach. Just over the West Midlands border, Coventry is about 5 miles away.
Approvals for an extension in Kenilworth
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.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
