NHER 12176 (Building record) - Crabbs Castle Farm

Cottages on this farm were among the first buildings in modern times to be built in concrete - a 19th century method of pouring between shuttering which led to sinkage in later years, so the process fell out of use and concrete was not revived as a building material until the 20th century.
Cottages now derelict - information from member of the public [1] in 1977.

Some of the cottages have now been rehabilitated, but it is not clear if these are the early ones. The original farm buildings of brick are dated 1799.
1983 Listing lists Nos.45-48 as original concrete cottages and dates them to 1878.
The main farmhouse is listed as brick, early 19th century; but the 1799 barns are apparently not listed.
