What to know before building in Barking and Dagenham
Much of the borough is interwar housing, including the Becontree estate — long runs of brick terraces and short terraces built by the London County Council, now largely owner-occupied. Single-storey rear extensions, hip-to-gable loft conversions on end-of-terrace houses, and garage or outbuilding conversions are the jobs we are asked about most.
Terraces on the same street often share a design, so matching the roof line, brick and window pattern of the neighbours makes an approval far more likely. We check your exact address with Barking and Dagenham Council records before we draw anything, and price the whole job — design, approvals and build — in one estimate.
