Why it was refused
- The development, by reason of its design and use of materials, represents an unsympathetic and poorly designed addition that fails to relate sympathetically to the built form, visual appearance and character of the host dwelling and wider surroundings. The development is therefore contrary to Policies 32 and 33 of the Horsham District Planning Framework (2015) and Policies HB3 and HB4 of the Horsham Blueprint Business Neighbourhood Plan 2019- 2036.
