Scheduled to open in 2020, the 70,000-seat stadium is scheduled to host the 2022 Super Bowl, and is also poised to play a key role in the 2028 Summer Olympic games. — Urbanize LA

It is clear not everyone is tightening the purse strings in tougher economic times following a year of record-smashing home sales in 2018.

The limestone clad mansion in Bel Air owned by the late TV executive Jerry Perenchio just got a price cut.

But at $245 million, the commanding French neoclassical residence, which measures 25,000 square feet, is still the most expensive listing on the open market in the U.S.

The Bailey House, one of the approximately 20 surviving Los Angeles residences from Arts & Architecture magazine’s Case Study House program is once again up for grabs.

Nearly everyone in Chicago is in favor of establishing the Obama library on the South Side. But now, “There’ll be more room for dissent, and more people in Chicago generally willing to speak their mind without fearing the Emanuel administration,” said Juanita Irizarry, executive director of Friends of the Parks, which has opposed the seizure of parkland. [...] Emanuel’s departure also gives hope to critics pushing for a more open process. — CityLab

Rafael Viñoly is best known for designing 432 Park, the tallest residential building in the Western Hemisphere, but he makes time for private homes, too–at least when they have headline-making features like a bullet-proof glass facade. His firm was first tapped to design this Upper East Side townhouse by Argentinian billionaire Eduardo Eurnekian to serve as his home and U.S. headquarters, but it looks like he instead decided to list the finished product for $50 million. — 6sqft

The billboard suggested the rapid rise in home values between 2008 and 2017 necessitates a steep tax aimed at speculative flipping. The proposed tax would grab as much as 100 per cent of the profit from a home resale during the first year of ownership, then decline by increments of 10 per cent over 10 years. It would target non-resident and resident buyers alike, including primary residences [...] the goal is to keep Toronto’s popular neighbourhoods affordable for all income levels. — The Globe and Mail
