Looking like trees - A spectacular steel roof spans the entry at the Marriot Hotel in Frankfurt/Main
Like trees looks the new entrance roof at Frankfurt “WestendGate”, also known as Marriott Hotel. The building 159 metre high and with 47 floors is settled opposite to the Frankfurt Fair and near to public green spaces, which are continued by the roof structure now.
Just/Burgeff architects with Asterios Agkathidis (a3lab) designed the aesthetic roof as a lucent, organic tree structure which is already recognized from a long distance. Together with Wilhelm and Partner (Stuttgart) Just/Burgeff architects sign responsibly also as structural engineers. Realised was the 1,000 square metre roof by Heinrich Rohlfing GmbH (Stemwede).
The roof consists of a steel pipe construction which rises up to 14 metres height. Arborescent supports form the tree top which develops as a double curved grid. The design of the tree elements changes according to static demands in height, number and density of the branches as well as in the pipe diameter. Lucent pneumatic ETFE cushions close the construction to large parts and offer protection from rain to residents and visitors.
