In 2017, the year marking the 50th anniversary of the legislation that introduced Conservation Areas, C20 Society were awarded a grant by Historic England to research C20th conservation areas. The project included research into the number of existing areas of C20 development designated as conservation areas, exemplary character appraisals for two potential new conservation areas, a scoping paper identifying a further 50 areas that the C20 Society believes likely to be suitable for future conservation area status, and guidance for local authorities on valuing C20 heritage either as stand-alone conservation areas or within areas designated for buildings of other periods.

If you work with conservation areas, you might find these 7 key points of good practice from the main report a useful reminder: Designating C20 Conservation Areas-good practice guidelines

The research into potential conservation areas was carried out by Neil Burton and Andrew Derrick of AHP and Esther Robinson Wild of Robinson Wild Consulting. Research into existing C20 Conservation Areas was carried out by staff and volunteers at the C20 Society. The project looked at around 65% of over 10,000 existing conservation areas in England, so if you spot any omissions, please email so that we can add them to the list.
