Harrow does not currently have a borough-wide Article 4 Direction for residential extensions or HMO conversions. Most householder permitted development rights apply normally in Harrow — though conservation areas and listed buildings still restrict PD. We confirm at the free site survey.
Harrow has 29 designated conservation areas, including Harrow on the Hill, Pinner Village, Stanmore and others. Planning applications within conservation areas require additional heritage consideration and often a Heritage Statement.
