EGR CONNECTS LUXURY HOSPITALITY WITH A RELAXING ENVIRONMENT ON MORE LEVELS THAN ONE …
A major hotel renovation and refurbishment in London is using its building fabric to connect with its environment , adjacent to one of the capital ’ s most historic green spaces .
London + Regional ( L + R ) Hotels ’ Nobu Hotel Portman Square runs along the east side of Grade II listed Portman Square , and is a complete remodelling of the former Radisson Blu . The 19,500m2 hotel is constructed in two blocks up to 12 storeys high , linked at ground level by a double-height glazed atrium .
The five-star hotel ’ s aesthetic has drawn on Japanese design principles , focusing on simplicity and natural over artificial . Thus , the roofs of the atrium and the ground floor retail area are both sedum blankets , delivered by Eco Green Roofs Ltd ( EGR ) for roofing contractor Able Waterproofing Ltd on behalf of main contractor Edgewater Contracts & Specialist Joinery Ltd .
Sedum roofs offer an aesthetically vibrant finish with colour all year round , offering a low maintenance living roof solution . They also offer at least 90 % coverage from install , delivering instant effect . This inadvertently proved crucial to the build , as L + R had a fixed opening date ( during the second pandemic restrictions ) , and therefore before some of the finishing touches- including one of the sedum blankets- were installed .
Able Waterproofing Ltd ensured the building was watertight by using single ply roofing across all roof areas .
Installed was EGR SB Sedum Blanket Green Roof System on to the waterproofing , by overlaying with EGR DBR cuspated drainage board , added EGR filter layer and EGR extensive substrate , completing the roof with EGR Sedum Blanket . The growing layers of extensive substrate and sedum have been carefully researched and formulated by EGR to balance water retention and drainage for the sedum whilst minimising the risk of invasive species bedding whilst the sedum establishes .
EGR also installed a fall protection system around both green roof areas .
James Foster , Director at Able Waterproofing Ltd , explained , “ The project was complex , due to the location and the restrictions that placed on access and deliveries ; it was further complicated once work began by travel and work restrictions caused by the pandemic . We have a long-standing relationship with EGR : its ability to deliver a complete project from design through to completion , with comprehensive reporting and technical support at all stages gives us trust in EGR ’ s professionalism , and the added peace of mind of a single source of accountability and communication throughout .”
