Westminster City Council has green lit plans to build a £12m library in Marylebone, to be partly funded by selling apartments on top of the building.
The library will be built in Luxborough Street and is due to be ready to open next year. Nine apartments will be built on top of the building and sold off, to help cover the costs of the project.
Currently, Marylebone library is in a temporary building following the council's decision to lease the library's previous home, Council House, to the London Business School.
The new library will be built over three storeys, with two below ground. The council said that the project will unlock nearly £10m of investment towards regeneration projects in the borough.
Architectural firms Child Graddon Lewis and Bisset Adams, which specialises in library designs, both worked on the project.
Westminster works together with Kensington and Chelsea and Fulham and Hammersmith to provide a shared tri-borough library service across all the areas. It previously attracted attention when library staff within Westminster wrote an open letter to council leaders, urging them to stop a "race to the bottom" and secure investment rather than cuts in the service.
David Ruse, tri-borough director of libraries and archives, said at the time that the £12m investment for the new Marylebone library was a sign of the council's commitment not to cut services.
