Conservation and heritage assets

Areas of special local character

There are 15 designated areas of special local character (ASLC) in Hillingdon. They are non-designated local heritage assets, which have a character and identity local residents value and the council wishes to preserve or enhance.

ASLC are designated based on their local architectural, townscape or historic merits, as defined in the adopted criteria for designating Conservation Areas and Areas of Special Local Character [13KB] .

The council has a rolling programme of historic asset designation and will continue to review areas of special local character. From time to time, we may extend existing areas or designate new ones. The council will consult all residents, stakeholders, local groups and other interested parties prior to designation. A designation is determined by the council's cabinet based on the outcome of the consultation and officers' recommendations.

Development proposals will be assessed against national and local planning policies. Our local planning policies seek to preserve or enhance the local architectural character and appearance of these areas.
