A blue roof for a green city

Blue-green roof solution on a London dwelling

CHALLENGE

8a Belmont Street comprises two unique semi-detached dwellings, which have been constructed in Chalk Farm, London by a private developer Maygrove Projects in collaboration with Martin Evans Architects. The total roof area covers only 55.03m² but features an unusual roof design; it is divided into five sections comprising two glazed roofs and three blue roof areas. For this warm roof construction, an alternative durable waterproofing was sought, suitable for blue roof application.

SOLUTION

Approved Roofing Contractor Gribben Solar Roofing provided an alternative blue roof solution to the original design proposed by the project architects, fully complying with their needs. Together with partner and single ply manufacturer RENOLIT they proposed a waterproofing solution for the blue roof in the form of a fully bonded RENOLIT ALKORPLAN L35A77 membrane, to be combined with the RENOLIT ALKORPLAN Green roof system. So, actually, a blue-green roof!
