Astor analyst's read

Hillingdon — 150 active Article 4 directions in our records; HMO-specific data thin. Verify council position.

Profile

Outer London suburban borough; lower-density family housing and semi-detached stock; significant green belt constraints.

Planning

150 active Article 4 directions in our records with only 1 flagged HMO-specific — heavy regulatory footprint but metadata coverage may be incomplete; verify with council on HMO-related restrictions.

Deal angle

Insufficient data for a confident read. Large A4 footprint and zero recent activity make bridging/HMO viability unclear without council verification.

1 commercial & employment zone designation
These directions apply to designated industrial estates, employment land, town centres, and retail zones (LSIS, MEL, SIL, CAZ etc.). They restrict certain permitted development rights within those commercial zones only — they have no effect on residential property.
Other Restrictions (2)
These 2 directions each apply to a specific designated area — not the whole borough. Check if your property falls within one.
