Planning and building regulation drawings in Sidcup (DA14)
Much of DA14 is 1930s bay-fronted semis and terraces laid out along the Cray valley. They wrap around the older core of Foots Cray village, where Victorian and Georgian buildings survive on the High Street, and some larger detached and interwar houses stand on roads backing onto Foots Cray Meadows. Rectory Lane, Maidstone Road and Church Road are among the district's other streets. For many of these houses the questions are the familiar ones for a rear extension, a loft conversion or a side addition: depth, height, the neighbours and whether permitted development applies.

The valley shapes much of the rest. Foots Cray Meadows is a Grade II registered landscape, and homes backing onto it or the River Cray face checks on setting and flood risk if an extension goes deep into the garden. Mature trees across the valley are often covered by Tree Preservation Orders, and many gardens contain protected trees that limit where footings and extensions can go, so a good plan starts with the trees in mind rather than a quick sketch of the back wall.
Bexley expects extensions to respect the established building line of the suburban streets. In Foots Cray itself the conservation area brings a closer reading of design. We check which of these applies to your house before we draw.
Planning in Sidcup: what to know before you apply
We know of no borough-wide Article 4 direction in Bexley that touches ordinary householder permitted development, and none is published for the DA14 part of Sidcup, so houses outside the conservation area can use their permitted development rights for rear extensions and loft work, within the usual limits. The exception is the Foots Cray Conservation Area. Inside it, roof enlargements, side extensions and rear extensions of more than one storey are not permitted development and need a full application, with design looked at closely. Houses backing onto Foots Cray Meadows or the River Cray can expect questions about setting and flood risk on deeper rear extensions, and protected trees in gardens can limit the footprint. Flats have no householder permitted development rights.
Applications are decided by London Borough of Bexley — its planning pages.
