Planning and Design Guide SPD

Last Modified July 18, 2016

Developments that are well-planned make a positive contribution to the built environment where people live, work and visit.
Our Planning and Design Guide aims to promote higher standards of design and layout in Hertsmere by setting out the key principles that we expect to be applied to new development in our borough. It has been adopted as a Supplementary Planning Document (SPD), which means that the standards and policies within it will be used when we assess planning applications.

The Design Guide sets out our principles in order to help homeowners, developers and anyone one else carrying out work which requires planning permission. It covers the layout and appearance of both domestic extensions and new house building, as well as commercial development, including changes to shop fronts.  

Please note that Part B: Permitted Development has been withdrawn due to continuing changes to the General Permitted Development Order.
