Plans for a works building in Kilburn that forms part of the High Speed 2 (HS2) railway development - Credit: Google Councillors will judge plans for a works building in Kilburn that forms part of the High Speed 2 (HS2) railway development at a meeting next week. Proposals for a headhouse building in Canterbury Road, will be presented to Brent Council’s planning committee on Monday (May 24). Developers hope to provide a mechanical and electrical plant, a fan room, and a series of vent stacks at the site, which would support the HS2 scheme. The general proposals have already been authorised under the High Speed Rail Act 2017 but councillors must decide whether they need to be altered to protect the wider environment.
