The dramatic transformation of the building included a new façade, a rooftop terrace amenity space, a green sedum roof and new landscaping and planting on Marshall Street and Sweet Street.The ChallengesThe rooftop terrace project required porcelain tile paving and artificial grass to be installed on a raised pedestal system in a very unusual arrangement, with only products from Raaft meeting the demanding specifications of this application.Due to the location of the terrace, wind uplift and fire resistance also needed to be taken into account.The InstallationA Raaft support system comprised of Preventa® pedestals, joists and floor structure panels provided a stable, easily-constructed raised platform for the tiles and artificial grass. The route of the pathways across the terrace required numerous small and angular tile cuts and for these, the floor structure panels provided a solid base that couldn’t be achieved with a standard pedestal system.Products UsedSupport Structure: Preventa pedestals, joists and floor structure panelsPorcelain Tiles: Atria Roma LeadPlanters: PlanterlineThe ResultRaaft’s almost invisible clip system prevents wind uplift yet allows tiles to be easily removed and replaced for inspection, repair and maintenance work. All Raaft products used on the project are BRoof(t4) or BS-EN13501-5 fire-rated, ensuring full compliance with fire safety requirements.
