South Mimms Conservation Area

Last Modified June 14, 2023

South Mimms Conservation Area was first designated in 1998. It includes the historic core of the village of South Mimms, contained within the linear development along Blanche Lane from the thirteenth century church of St Giles to the small village green and westwards up to the M25 motorway.   

We are currently conducting a consultation on the South Mimms Draft Conservation Area Appraisal - 2020 (PDF 13.6Mb). The appraisal sets out a number of recommendations to help preserve and enhance the character and appearance of the area, including some proposed revisions to the Conservation Area boundary.

All representations for the consultation must be made by 12pm on Friday 28 July 2023. Any comments or queries regarding the Conservation Area Appraisal and associated recommendations are welcomed by email to local.plan@hertsmere.gov.uk or should be made in writing to the address below:

As part of these proposed revisions, the Conservation Area Appraisal has identified the following locations for inclusion within the Conservation Area:

  • Hazeldene and Hazelmere, St Albans Road
  • Ingham Lodge and Cedar Lodge on the western side of Greyhound Lane
  • New Grange, off Blanche Lane


It is also proposed to amend the Conservation Area boundary to ensure it fully aligns with the property boundaries at:

  • Arlingham House, St Albans Road
  • Properties on the western side of Hamilton Close   
  • A property on the western of Blanche Lane


As part of this review a new Conservation Area boundary is proposed. The following revisions are being proposed:

    • Removal of verges and front gardens along the eastern side of St Albans Road, including the roundabout with Cecil Road.
    • Removal of two small areas of land to the south and west of the existing conservation area, and the removal of an open piece of agricultural land to the north-west.


Please note that the report was initially prepared in 2020 but public consultation was delayed due to the Covid-19 pandemic.
