SLHRA Current Planning Applications

Due to the geography of St Leonard's Hill, planning applications can affect a large number of residents of St Leonard's Hill. The Royal Borough of Windsor and Maidenhead Planning department do not distribute planning applications to the entire hill and instead notify those properties directly next to or overshadowed by the development

To help residents, we will list planning applications for properties on St Leonard's Hill.
