Project case studies

81 real outcomes across London.

London terraced street — typical residential housing for architectural drawings in London

What do these case studies have in common?

Each one was decided by a case officer, not a committee. Across London 97.0% of planning decisions are delegated, and 83.0% of the 77,680 householder applications decided in the three years to March 2026 were approved. Our part in each began the same way: a measured survey from £245, then a drawing set from £840.
