Icopal’s green biodiverse roofing and living walls have been installed to support the BREEAM Excellent rating and create a pleasant outdoor space for occupants at 20 Bentinck Street, a premium mixed use development just off Marylebone High Street in a conservation area in the heart of London.

Urban Regeneration

The original building, in need of a complete refurbishment, was subject to a £15m design and build project. In keeping with its Georgian beginnings, the building’s original Grade II listed façade was retained with the construction of a new five-storey building plus basement creating 40,000 sq ft of premium offices and three luxury penthouse apartments totalling 4,300 sq ft.

Achieving BREEAM Excellent status was one of the primary objectives for this project. One contributory factor to realising this was the specification of a green roof and living wall solution.

London-based roofing specialist, McCormick Flat Roofing Ltd – an Icopal approved installer - specified the Icopal roofing solution winning the tender for the install. Icopal’s innovative range of high performance green roofing systems, with its wide product portfolio, offered flexibility of design with guaranteed quality and long-term durability.

Installed to the first and fourth floor roof deck areas, the Icopal green roof system comprises a series of components including Icopal’s Sureplan FPO single ply roofing membrane bonded to Thermazone insulation, a highly efficient PIR rigid insulation, and in turn this was laid over Icopal’s Monarflex vapour control layer. The system was finished with Icopal’s green biodiverse roofing and living wall feature.


ICS1076-Bentinck-Street-Marylebone-02“Commenting on the installation, McCormick Flat Roofing Ltd’s managing director, Stewart McCormick said: “We worked closely with Icopal’s technical advisors to ensure the specification was exactly fit for purpose. The team’s experience in waterproofing technology allowed us to deliver the correct specification of roof membrane and green roof system to suit the criteria for the Bentinck Street project, based on the choice of landscaping, performance and robustness required.”
