Qantas House, No. 1 Chifley Square, Sydney
Qantas House is a fine example in the Australian context of intact, post-war, multi-storeyed office buildings from the first phase in the 1950s, and is from the small group in Sydney of this group designed prior to the amendments to the Heights of Buildings Act in 1957 that heralded the subsequent 'high-rise' phase. It has particular rarity within Australia for its unique shape, the outstanding quality of its curtain wall facade and its contribution to its urban setting. As such, it is considered to have heritage significance at a national level.
