Planning and building regulation drawings in Chadwell Heath (RM6)
Chadwell Heath is an interwar suburb strung out along an old main road, on the edge of the great Becontree Estate. Most of the houses are semi-detached or terraced homes from the 1920s and 1930s, with some Victorian and postwar housing mixed in. Thackeray Drive, Waldegrave Road, Baron Road, Grove Road, Chadwell Heath Lane, Mill Lane, East Road, Station Road, Jarrow Road, Chadville Gardens, Burlington Gardens and Farrance Road all appear in the district. Regular interwar plots with usable gardens explain why rear additions and loft rooms come up so often here.

One thing to settle first is the council. RM6 straddles the boundary between Barking and Dagenham and Redbridge, so which borough's householder guidance applies depends on the street, and it is worth confirming that before any design work starts. This page follows Barking and Dagenham, whose permitted development limits and design guidance govern extension depth, height and roof form here. The council's own record lists a Chadwell Heath conservation area, while the record for this district holds none, so we confirm whether any designation reaches the address.
The street pattern sets the design tone. Regular building lines, paired semis and front-garden setbacks mean side and front additions are judged against a settled rhythm. Two-storey side extensions can erode the spacing between pairs, so they need careful handling. Single-storey rear extensions suit the plots, but bigger schemes still have to respect neighbours, which means overshadowing, overlooking and the party wall with the adjoining house. Matching the original facing brick, render, tile-hanging and roof tiles stops an extension reading as an afterthought.
Planning in Chadwell Heath: what to know before you apply
A borough-wide Article 4 direction from the council takes away the permitted development right to turn a house into an HMO, and that sits alongside its design guidance for ordinary householder work. A change to a small HMO for three to six unrelated sharers therefore needs permission. Extensions and lofts follow the national permitted development limits; a scheme that exceeds them, a side extension of more than one storey, or work on a house in a conservation area needs a householder application. Roof form, depth, height and the visibility of side additions are what officers weigh, together with neighbour amenity. Flats have no householder permitted development rights. A planning application needs the correct ownership certificate or notice. We confirm the borough and the constraints for your street before drawing.
