Warwick District Council is the local planning authority, and the district has 29 conservation areas. The Kenilworth Conservation Area is the one that matters here, and it includes Avenue Road, which surprises people who assume conservation status stops at the old town.
Avenue Road and the villa quarter
This is the point most often missed in Kenilworth. The Victorian and Edwardian streets around Avenue Road are inside the conservation area, and those are exactly the houses people most want to extend, because the plots are generous and the buildings will take it. Being in a conservation area reduces the permitted development limits and removes permitted development rights from side extensions entirely. So the most extendable houses in town are also among the most controlled, and the design has to start from that rather than discover it.
The old town
At the castle end the buildings are older, listing is more common, and the plots are tighter. Listed building consent is separate from planning permission and covers the inside as well as the outside. We ask about listing on the first visit.
Article 4
The council has issued an Article 4 direction on land known as Castle Pavilion, following representations from residents, councillors, the town council and the local MP. It applies to that land rather than to the town generally, but it is a reasonable reminder that in Kenilworth the community takes a close interest in what gets built and where.
Everything else
On the twentieth century housing the ordinary rules apply and a single storey rear extension often falls within permitted development. Permitted development is not an exemption from Building Regulations, and a full plans application is still required. We do not make that application, but we arrange and meet the inspections that follow it and we see the work through to sign off.
