How Sutton decides on small housing schemes
Every decision on sites of nine units or fewer, coded from the council's own register and refreshed each quarter. What gets built, what gets approved, and what trips applications up.

Thinking about a specific site?
The dashboard gives you the borough picture. If you’re weighing a particular site, the Red Line Review is an independent second opinion before you commit six figures — one sentence on what I’d do if it were my money, and why.
Applications. Sourced from the Greater London Authority (GLA) Planning Datahub and Sutton Council’s online planning register. Covers full planning, householder, and minor residential applications of nine units or fewer decided in the window shown above.
Decisions and timing. Outcomes and determination times are taken from the council’s published decision notices.
Refusal reasons. Extracted from refused decision notices that were publicly available. Not every refusal has a readable notice, so totals count all refusals but the reason breakdown covers only those we could read.
Scheme classification. Site types (conversion, demolish & rebuild, extension, and so on) are coded from application descriptions and drawings. Areas are mapped from postcodes and ward names using the council’s own sub-area definitions.
Update frequency. Refreshed quarterly. Next refresh: July 2026.
Nothing here is planning advice. Outcomes are historical and do not predict individual cases. Approval rates vary with site specifics, policy context, and case officer.
