Two tapered towers linked by a multi-storey skybridge form Collins Arch, a mixed-use skyscraper by Woods Bagot and SHoP Architects in Melbourne, Australia.
Located at a prominent site in the city's central business district, the 164-metre-high Collins Arch contains apartments, a hotel, offices and public facilities.
Its glass-lined arched form was developed from the inside out to ensure that every space has ample natural light and views outside.
According to Woods Bagot and SHoP Architects, the result is a dramatic landmark that simultaneously "settles comfortably into the skyline".

"The skybridge connecting the two buildings is not simply decorative," said Bill Sharples, founding principal of New York studio SHoP Architects. "It maximizes views and sunlight for office, hotel and residential occupants of the two buildings that, on the ground, meet public space and commercial requirements," he said.
"The ground plane was always where the project started; the building's form was a result of the program."
It is intended to sit "comfortably" in the skyline
Woods Bagot and SHoP Architects won a competition to design Collins Arch in 2014, which was initiated by Cbus Property.
The competition called for a landmark development for Collins Street ? a major road in Melbourne with a mix of heritage buildings and skyscrapers.
