This 27,000m2 mixed development in West Dublin will be Ireland's first large scale low-energy project using innovative sustainable technologies. The site forms a long triangle beside the major highway into the city from the West. The building runs North-South on the two lower floors, creating a folded public realm between two rows of shops and offices. The upper level residential and hotel blocks crank East-West across the lower plan, forming a series of courtyards and a stepped rhythmic green wall to the main road. The scheme is set through with gardens and planted roofs, with a three-dimensional route past a new public library to the upper gardens.
