Westminster council has approved Ken Shuttleworth's plans to add a sixth floor to 10 Weymouth Street - part of which houses the ARB - and extend the building's rear to add 12 new apartments and 140m2 of extra office space ( Make to build luxury development next to ARB ).
Led by Ridgeford Properties, the scheme will incorporate various eco-features including a ground-source heat-pump system for heating and cooling and a green meadow roof.
Marylebone has undergone a 'huge change' over the past five years, but Ridgeford boss Chris Murray is convinced the property hot-spot still has massive development potential.
Commenting on Make's design, he said: ' -by extending and enhancing the current building, we will unlock the site's true potential by providing generous-sized, high-specification apartments whilst meeting the latest environmental and sustainable criteria.'
Work will start on site this October, with completion scheduled for March 2009.
