The Badboot project has been developed to cover and extend the operation times of a roof top bar on a barge in Antwerp Harbour. The structure has been designed to be used all winter and part removed in the summer to open up the roof. The structure is 9m wide and 18m long and constructed from white powder coated steel to complement the design and lines of the existing boat. The air cells are all clear allowing for the continuation of the panoramic views across the harbour. The whole structure seals to the boat and allows the space to be comfortably heated in the winter. The boat itself is used as an ice skating and restaurant/events space in the winter and in the summer the ice rink reverts to a swimming pool.
