Liberty Lake-based Greenstone Corp. has started the permitting process for a $3 million mixed-use building overlooking the Spokane River gorge in the Kendall Yards urban ridge development, says Greenstone CEO Jim Frank.

The three-story, 27,000-square-foot structure planned at 1133 W. College would have six retail units on the main floor and a total of 24 studio and one-bedroom residential apartments on the second and third floors, Frank says.

The retail floor spaces would have 1,000 square feet to 1,100 square feet of floor space, and three of them would have live-work spaces with sleeping rooms, site plans on file with the city of Spokane show. The studio apartments would have 640 square feet of living space and one-bedroom units would have 740 square feet of living space.

A Greenstone construction arm is the contractor on the project, and Pacific Design Group of Washington PS, of Spokane, designed it, Frank says.

The project would include a 133-space parking lot, which would be constructed on the north side of the building.

Greenstone hasn't announced any tenants for the building yet.

The building would face the north side of Summit Parkway, which Greenstone separately plans to extend east to Monroe from its current terminus at Cedar Street. The Summit extension, which is expected to begin in late summer, will cost $1 million, Frank says. When fully developed, Summit will be the main boulevard running east and west through the 78-acre Kendall Yards urban village.

The building would be the fourth commercial project in Kendall Yards. Construction is nearly complete on two others in the west 1200 block of Summit, each of which will have about 13,000 square feet of floor space and cost about $1.2 million. Spokane-based free weekly newspaper The Inlander will own and occupy one building, and Spa Paradiso will lease most of the floor space in the other.

Central Food, a new Spokane restaurant, recently opened in Kendall Yards' first commercial building, a $1.5 million, 5,200-square-foot Cedar Plaza building, at 1334 W. Summit.

Just west of the commercial developments, Greenstone is developing the $9.5 million, 84-unit Bridgeway Apartments complex.
