The design, originally costed at between $110 and $128 million, was complex and irregular, with gently angled 'cranked' geometries predominating in both the planning and the facade treatment of the various buildings and the wintergardens that surrounded and defined the open spaces. A series of 'shards' provided vertical accents, while interconnected laneways and stairways and the wintergarden would connect Flinders Street to the Yarra River. The open square was arranged as a gently sloping amphitheatre, focussed on a large viewing screen for public events, with a secondary sloped plaza area on the main corner. The design was widely supported by the design community but was less popular with the public. The design was also soon criticized when it was realised that the western freestanding 'shard' would block views of the south front of St Paul's Cathedral from Princes Bridge.
