The world's most visited architecture platform

Canada’s future tallest building, The One, has broken ground in downtown Toronto. Designed by Foster + Partners, the 85-story building will become the country’s first supertall skyscraper (commonly defined as taller than 300 meters/980 feet), rising to a peak of 306 meters (1,004 feet). The tower will also take over the title of Canada’s second tallest manmade structure, behind only the CN Tower.

Located at the corner of Bloor Street and Yonge Street on the border between downtown and Yorkville, the residential tower will respond to its unique context, embodying the neighborhood character of Yorkville, the bustling commercial life of Bloor Street and the local heritage of Yonge Street.

The renovation of the Aalto University Harald Herlin Learning Centre in Otaniemi, designed by NRT Architects in collaboration with JKMM Architects (interiors), has been selected as the winner of the 2017 Finlandia Prize for Architecture. Completed in 2016, the project is the first renovation to be awarded the prize. The original building was completed in 1970 to fit into the Alvar Aalto-designed Otaniemi campus plan.

Now in its fourth year, the prize was established to “increase public awareness of high quality Finnish architecture and [to highlight] its benefits for our well-being.” Last year, APRT Architects’ Rovaniemi Sports Arena, Railo took home top honors.

We now know that first, we form the cities, but then the cities form us.

Meet 81-year-old Danish architect Jan Gehl who, for more than fifty years, has focused on improving the quality of urban life by helping people to “re-conquer the city.” Gehl has studied the relationship between life and form since the mid-1960s, when he started questioning the modernist approach of looking at the architectural model from above instead of from the inside. The architecture of that time was very often "an obsession with architecture for architecture’s sake," and took very little interest in the inhabitants.

The 65-story, winding glass skyscraper designed by BIG for New York’s Hudson Yards neighborhood, "The Spiral," is one step closer to realization, as developer Tishman Speyer has secured the necessary air rights for the structure, The Real Deal reports.

The $157 million deal was made between the developer and the Hudson Yards Infrastructure Corporation and the Metropolitan Transportation Authority for 669,000 square feet of development rights, equalling $235 per square foot. After adding in the square footage acquired in two separate deals in 2015 and last year, Tishman Speyer has now spent $265 million to gain more than 1.23 million additional square feet of buildable space for the 1,005-foot-tall tower.
