Leicester City Council is the local planning authority and the city has 24 conservation areas, from the former villages of Evington and Humberstone through to the Edwardian High Street and Stoneygate.
Windows and doors are a planning matter in two of them
This is the single most important thing to know about altering a house in Leicester. Article 4 directions apply in the Stoneygate conservation area and to most properties in the New Walk conservation area, and what those directions do is require planning permission for external alterations including the replacement of windows and doors.
Replacing your own windows is something almost everybody assumes is theirs to decide. In those two areas it is not. The direction exists because the windows are a large part of what makes the streets look the way they do, and a run of Victorian sashes with three modern units dropped into it is visible from a hundred yards. If you live in either area, treat windows and doors as an application rather than a purchase, and talk to us or to the council before you order anything.
New Walk
Designated in 1969, one of the first three conservation areas declared in the city and now the second largest, New Walk is protected closely and the Article 4 covers most of it.
Everything else
Outside the designated areas 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.
