Air Monitoring Unit Marylebone Road London NW1 5JX

Awaiting decision Westminster 26/07135/FULL Full applications

Still open. Anyone can comment while the consultation period runs, and comments go to the council rather than to us.

Proposal

Retention of Air Quality Monitoring Station located directly outside of the University of Westminster on Marylebone Road. No change of use but commitment to work with local partners including Baker Street Quarter Partnership and the Environment Agency towards a refreshed container over the next few years.
