The Luton Street regeneration scheme near Church Street has opened delivering 171 new homes, a leisure centre and a new green route.
The latest section of the wider Church Street redevelopment in Lisson Grove contains 62 affordable properties.
Westminster Council first unveiled proposals for the Lisson Grove area in 2017, including plans for a new pedestrianised “green spine” connecting Church Street with Marylebone, as well as several new green spaces and play areas.
Councillor Matt Noble, the cabinet member for climate action, regeneration and renters said: “Building genuinely affordable and social homes for local people is at the top of the list of priorities for the new administration and so we are pleased to be able to offer more social homes than originally planned as part of the Luton Street development.
“This development is just the beginning, and we want to continue to deliver bigger and more affordable homes, as well as make changes that will revitalise areas for local communities and provide better, greener places for residents to live.”
The Luton Street regeneration also includes a new sports centre, to be operated by Everyone Active which manages four other gyms within the Westminster area.
A pedestrianised section between Fisherton Street and Salisbury Street will form part of the green spine which may eventually stretch from Bell Street to the Regent’s Canal.
Earlier this year Broadley Street gardens were redeveloped together with a new play area and footpath on Lisson Street.
The new Luton Street development is built on the site of the Marylebone Coal Yard which formed part of the Marylebone Goods Depot, the original brick wall of which still stands today.
