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 is set out in sections, and sets out our principles in order to provide clarity for 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.
