Design & Planning Database · October 2026
What London councils actually approve
Build Team has secured planning approval for 1,403 projects across 22 London boroughs since 2007. This database lets you see what has been approved near you, and what each council tends to allow: boundary wall heights, whether wraparound extensions get through, and how conservation areas are handled.
