Under consideration

No decision has been issued yet. Plota predicts a decision between 30 Nov 2026 and 7 Dec 2026, from Southampton's recent utility and infrastructure works.

Site constraints 4

Nutrient neutrality catchment: Solent: Includes Chichester and Langstone Harbours SPA/Ramsar, Solent and Southampton Water SPA/Ramsar, Solent Maritime SAC, Portsmouth Harbour SPA/Ramsar
New homes and overnight accommodation must show nutrient neutrality before approval.
Natural England advice: extra wastewater in these catchments harms protected habitats, so schemes must offset their nutrient load, usually through credits.
Article 4 direction
HMO. Named permitted development rights are withdrawn here.
An Article 4 direction withdraws particular permitted development rights, so work that would normally need no application needs one here. Not every council has published its directions.
Also on the record
Local nature reserve 395 m away: Lordsdale Greenway; Inside the Southampton built-up area.
Not affected
Outside flood zones 2 and 3 · Not green belt · No listed building at the site
