Real estate developer Urban Villages plans to open Hotel Westland at 100 S. King St., inside a 1907 building that will become a 120-room hotel with a restaurant, coffee bar, meeting spaces, a penthouse suite for events and an open-air rooftop bar, Pioneer Square’s first.

The environmentally conscious hotel, which plans to sequester the carbon it emits and remove additional carbon from the atmosphere, is the second of its kind in the United States, according to its developer. Urban Villages is also behind Populus, expected to open in Denver next summer. Westland is the developer’s third installment in its Seattle RailSpur complex, a carbon-negative “micro-district” that includes offices at 419 Occidental Ave. and mixed retail-residential spaces at 115 S. Jackson St.. The connecting alleyways will host art, music, and culinary programming, according to Urban Villages representatives. The complex is named for the industrial railways that once ran through the area.

“The goal here is to have as many activities as we possibly can so it’s really activated 18 hours a day, 365 days a year,” Grant McCargo, Urban Villages CEO and founder, said at an event on Wednesday.
