Cox Architecture is the firm behind the design for a hotel expansion of the Four Points by Sheraton hotel in Sydney's CBD which would make it Australia's largest hotel.

The news comes after a spate of hotel designs which have been submitted for Barangaroo's Crown resort, the upgrade of the Park Hyatt and Cox Architecture's own award winning hotel The Darling which will address a shortage being experienced in the city which averages over 80 per cent occupancy.

The Sydney Morning Herald reported that the design will include vertical louvres on the tower and the use of low reflection materials on the side of the building that could reflect onto the nearby Western Distributor.

The Sydney Harbour Foreshore Authority and NSW Heritage Office have warned of the harm that could possibly come to nearby historic buildings such as the Corn Exchange and the Dundee Arms Hotel.

Architect Philip Cox director at Cox  Architects has been openly critical of the development of the multi-billion dollar, exhibition, convention centre and hotel precinct in Darling Harbour which will see the demolition of his award winning convention centre built in 1988. Cox told the SMH that his proposal 'doesn't bear comparison' with the redevelopment.
