Awaiting decision Westminster 26/06001/FULL Full applications

Works: New dwelling Extension Windows or glazing Domestic

Read from the description, not a valuation. How we read the register

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

Proposal

Amalgamation of the existing lower and upper-ground flats and adjoining garden areas to form one duplex dwelling, including internal reconfiguration, formation of a new internal stair, incorporation of one existing pavement vault for ancillary plant and storage use, a lower-ground rear infill extension with glazed roof and roof terrace on top, associated external works and installation of an air-source heat pump within the combined rear garden.
