Kenilworth is a good town for extensions and a town where people regularly get a nasty surprise, and both facts have the same cause.
The Victorian and Edwardian houses around Avenue Road sit on plots with real space in them. They will take a substantial rear extension, they usually have side access, and structurally they are straightforward to work on. They are also inside the Kenilworth Conservation Area, which reduces the permitted development limits and removes permitted development rights from side extensions altogether. The house that looks like the easiest extension in town may need a full application, and that is worth knowing before an architect is paid.
On the twentieth century housing across the rest of the town the ordinary rules apply. A single storey rear extension of up to four metres on a detached house or three on a semi can fall within permitted development, with a driveway for the skip and side access for the materials. These are the most predictable extensions we price here.
At the castle end the plots are tighter and listing is more common, so the design starts from the constraints rather than meeting them halfway through.
On the unlisted later stock there is also the larger home extension route: up to eight metres on a detached house or six on any other, by prior approval rather than full permission, with neighbours notified and an answer in about six weeks.
Our extensions work is described in more detail there, including how the inspections fit around the build.
