Skyscrapers usually start off bulky at ground level and become slim as they rise. Vancouver House, a twisting condo tower by Danish architect Bjarke Ingels, does the oppostie.
The lower floors of the 59-storey building, set to open in 2019, will squeeze into a narrow triangular lot constrained by highway off-ramps and an adjacent park.
Once the tower has cleared the surrounding cityscape, it will curve outward, blooming into larger penthouse floors. The Westbank-developed Vancouver high-rise just won the 2015 World Architecture Festival's "Future Project of the Year" award; judges called it a "delightful use of a typically abandoned public space".
