Design and access statements are now required to support all but householder applications.
The application drawings should show the layout on the site or, for outline applications, an indicative layout. The statement should explain why this layout has been chosen, and how it will work and fit with its surroundings.
For small developments this may be very simple, for example, just saying that the building faces an existing road. But for larger plans, the layout may be balancing a variety of design features such as solar gain, crime prevention and accessibility. In these cases, statements should clearly explain the design decisions that have been made.
