‘Green Roof Project of the Year 2016’ was awarded to Radmat and Approved Contractor Prater in the Sustainability category of the Roofing Awards on Friday 13th May.
Designed by BDP in consultation with patients, their families, the Princes Foundation and National Arts for Health, the Alder Hey Children’s NHS Foundation Trust in Liverpool is the UK’s first NHS health park for children. It was a drawing by a 14-year-old patient that inspired the project’s final design.
A key feature of the design is the three green roofed ‘fingers’ that curve at up to 45 degrees from the 4th floor to ground level, integrating the hospital wards into the surrounding parkland. Waterproofing the steep slopes required the installation team to work using a mixture of abseiling equipment and telelifters to install the Radmat waterproofing system: a two coat spray applied elastomeric Liquid Applied Membrane followed by ProTherm inverted roof insulation and a substrate based wildflower meadow green roof system.
The 52,600m2 main hospital and 9,500m2 outpatient’s department have already won a number of RIBA Awards and can now add a Roofing Award to the many accolades it is no doubt going to receive.
