Whilst research has lead us to believe that a number of Rowcon houses were constructed in Calderdale, none have yet been identified.

In general, there is very little resource information available regarding the Rowcon constructions. This may be partly due to the low number of houses that were constructed. 1700 dwellings if considered to be a fairly low volume level in the construction market.
