DOWH does not provide practical advice on planning or repair and conservation but there is useful information to be found on the internet. Some of the most valuable links are given below:
The Society for the Protection of Ancient Buildings (SPAB) is the best first port of call for traditional building dating from before c. 1750. https://www.spab.org.uk gets you to the society’s ‘Knowledge Base’. Good advice is available there on energy efficiency in old buildings (including loft insulation) along with handy guides on renders, rainwater fittings, repointing, traditional materials and suchlike.
Although DOWH’s focus is on houses dating from before the mid eighteenth century, most of these will have been remodelled and extended later. The Georgian Group and the Victorian Society have advice notes on things like period fireplaces, sash and casement windows and interior decoration.
