The competition-winning Calton Gate scheme will link Waverley Valley to the new parliament, as well as creating a mixed-use 'quarter' within the Scottish capital's historic heart.
The £180 million redevelopment will feature a new urban square lined with shops, cafés and cultural spaces. There are also proposals for a 200-bed five-star hotel as well as offices, artists' studios and nearly 300 homes on the 5.2-acre site - most of which was once the New Street bus depot.
Developed for Mountgrange Capital, it is envisaged that a number of different architects will design the individual buildings within AMA's masterplan.
The practice aims to submit a 'phased' planning application over the next year and hopes to gain final planning approval by mid 2006.
