Employment union Unison has been granted planning for a development near Euston train station.
The plans include designs for two office buildings, which will be built on the site of the former Elizabeth Garrett Anderson Hospital at Huntley Street.
Local architects Squire and Partners designed the scheme, which will become the union’s’ headquarters if it gains approval from the Greater London Authority.
"The main aim behind the proposals is to retain Unison HQ in a central London location close to transport links and its current location," Michael Squire told Camden Council during a recent development forum.
The council approved the scheme, which will also see the renovation of the former hospital buildings and the construction of 47 apartments.
Mr Squire explained that the buildings’ design has been "carefully considered in the context of the surrounding area, particularly with regard to daylight and sunlight".
London’s commercial property benefits from local and international transport links and direct connections to the City.
