Netley Campus, located close to Euston Station obtained planning permission last month and work has already commenced on site, due for completion in 2014.
Following an extensive examination of options, the proposals for London Borough of Camden and the School are to make improvements to the Victorian building and redevelop the remainder of the site with new education and community facilities.
The project is to be entirely self-funded through the development of residential apartments above the new building and on an adjoining site.
