John Laing and Son: Easyform House
Note: This is a sub-section of John Laing and Son
Designed by John Laing and Son, as they are poured in-situ into moulds type designs developed from 1919 onwards, they do not suffer the problems of many steel framed buildings. The rare Mk1 version had 8 inches (20 cm) thick solid no-fines clinker concrete walls, built in the period 1919 to 1928. The more common Mk2 version from 1925 to 1945 had cast in situ cavity walls, 3 inches (7.6 cm) thick inner and outer leaves with 2 inches (5.1 cm) cavity, usually finished externally with stone dashed render coat. Post-1945, the Mk3 version, which makes up the majority of houses, was modified to specification, and hence had cast in situ concrete walls, inner and outer leaves of 3 inches (7.6 cm) thickness separated by a 2 inches (5.1 cm) cavity, and reinforcement in both skins located in four horizontal bands above and below window openings.
