Planning application

Cornerstone Apartments 47 Princes Gardens London

Awaiting decision Westminster 26/05796/CLOPUD Lawful development

Works: New dwelling 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

Confirmation that the proposed internal reconfiguration of small parts of the building does not constitute development within the meaning of Section 55 of the Town and Country Planning Act 1990 because the works comprise internal alterations only and do not result in a material change of use. The proposal involves minor adjustments to the internal layout of Units 1-6. The works comprise the relocation of internal partitions and the closing and opening of internal doorways to redistribute small areas of floor space between adjacent dwellings. These alterations simply redistribute small areas of existing floor space between neighbouring flats to improve their internal layout. Each dwelling will remain a separate self-contained Class C3 unit before and after the works.

About lawful development applications

A lawful development certificate is a legal determination that existing or proposed works do not need planning permission; the merits of the scheme are not considered. More in our guide to planning application types.
