The blue building nears a sellout in River North

When I visited Superior 110 recently, only three units in this striking boutique high-rise were still available for sale.

The remaining units all occupy a full half-floor and range in size from 2,290 to 2,550 square feet. They feature 3 bedrooms, 2 ½ or 3 baths and are priced from $1,129,000 to $1,199,000.

Bessie Alvarez of @properties met me at the building and gave me an overview as she waited to meet a buyer for a scheduled showing.
