CHICAGO—The city is in the midst of an apartment-building boom, but some companies have also begun developing condominiums. Belgravia Group, Ltd. has just started sales at Three Sixty | West, an 11-story building with 38 condominiums in Chicago's River North neighborhood. The Chicago-based firm will break ground in the fall 2017, and plans to deliver the units in late summer 2018. At a May 6 launch event, Belgravia officials said almost 20% of the residences were already sold.

“This pocket of River North has a very loyal following among its residents,” says Liz Brooks, vice president of sales and marketing for Belgravia. “Once people move here, they don't want to move out. But life happens and people usually outgrow their starter condo, so they look for that next step up. They want a larger, yet gracious home with more refined finishes and features, not to mention discerning amenities, and this building delivers on all fronts.”

Priced from $1.1 to $1.8 million, the three-bedroom/three-bath residences at Three Sixty | West. will range from 1,735-2,396 square feet. Two three-bedroom/three-bath penthouse residences with large outdoor terraces are also available at Three Sixty | West. Prices for the 2,550-square-foot A penthouse plan and the 2,645-square-foot D penthouse residences are about $2.1 and $2.2 million, respectively.
