Greenstone Corp., a Spokane-based development and construction company, plans to build a $2.5 million office structure at Liberty Lake and consolidate its offices there next year.


The project still is being designed, so some details havent been firmed up yet, Greenstone President Jim Frank says. As currently planned, however, the building would be a two-story, 24,000-square-foot structure.


The structure would be on the south side of Appleway Avenue, just east of the Liberty Lake Town Center, a retail complex anchored by an Albertsons Inc. supermarket.


Greenstone needs about 12,000 square feet of floor space for its offices and plans to lease out the rest of the space in the building, Frank says.


The company hopes to break ground on the project yet this fall, but Frank says it might have to wait until early spring to begin the project. If Greenstone started work this fall, it could complete the project as soon as June, he says.


The company will act as its own contractor on the project, Frank says.


When the building is completed, Greenstone will consolidate its two offices there. Its headquarters currently are located in a 5,000-square-foot space in the Marycliff Hall building at Marycliff Center, on Spokanes South Hill, and it also operates a 2,000-square-foot field office in Post Falls.


The new building will be situated on about an acre in an eight-acre parcel Greenstone owns. The company hasnt determined how or whether it will develop the about seven remaining acres of land there.


Greenstone, which Frank founded in 1983, and a sister company, Greenstone-Kootenai Inc., which does business in Idaho, currently are developing a handful of big planned-unit developments in the Spokane-Coeur dAlene area, including MeadowWood At Liberty Lake, Bella Vista Estates in the Spokane Valley, Coeur dAlene Place at Coeur dAlene, and Montrose At Post Falls.
