The Department’s English House Condition Survey collects information on the number of homes which have solid walls. This is a sample survey designed to provide national and regional level estimates only. The most recent available results from the survey are for 2005 and this estimated that there were 6.7 million homes with solid walls in England, of which 764,000 were in the South East region.
These figures for ‘solid walls’ include all homes without cavity walls. In the main these are solid masonry walls but will also include some homes (totalling less than 4 per cent. of the whole housing stock) of prefabricated concrete or steel/timber frame construction. The numbers of homes in these latter categories are too small to estimate reliably through the sample survey.
The Department does not collect this information at a local level and is therefore not able to provide the number of homes which have solid walls in Castle Point or for Essex.
