The Crossfields Estate is an early postwar social housing estate in the Deptford of Lewisham, London. The estate is divided into three by the east-west running North Kent Line, and by the north-south running A2209 Deptford Church Street. It was constructed in the late 1940s and, when completed, consisted of 12 blocks, two of which have since been demolished. All the blocks were constructed out of brick, and the flats are deck-accessed.
