Prium Companies LLC, the Tacoma-based developer that owns the big Rock Pointe Corporate Center just north of downtown Spokane, says it plans to build a fifth office building there and expand one of the complexs two parking garages.


Prium bought Rock Pointe, located between Washington and Atlantic streets north of Boone Avenue, from Spokane developers Walt and Karen Worthy for $82.8 million in 2005. The complex includes 563,000 square feet of floor space in four buildings, parking for 2,000 vehicles, and about 13 acres of land.


Priums tentative plans for the coming project call for a six-story, roughly 125,000-square-foot office structure east of the developments current buildings, on the east side of Normandie Street, says Robert Marmaduke, an engineer at the company. Years ago, the property housed Weinstein Beverage Co., a 7UP distributor, but has served as a surface parking lot for Rock Pointe since the Worthys bought the property in 2000 and razed the building there.


Prium hasnt established a final estimated cost for the office building, which is still in its preliminary design stages, but its cost likely will be around $15 million, Marmaduke says.


The expansion project also would involve adding roughly 250,000 square feet of space to the Rock Pointe West parking garage. Prium doesnt have an estimated cost ready to release for the parking garage addition yet, Marmaduke says.


The company is conducting a feasibility study, and Spokane-based Coffman Engineers Inc. has done preliminary work on the project, he says. Prium likely would talk with OMS Inc., of Spokane, about being the architect for the project, he says. Marmaduke hopes to submit preliminary plans for the project to the city of Spokane in January, in which case construction could start in December 2008 and be completed by the middle of 2010, he says.


The Worthys launched the Rock Pointe Corporate Center in 1986, and built the four office buildings and two parking garages there in phases. Rock Pointe East, which was completed in 1998, was the most recent addition to the complex.


Priums other real estate holdings in Spokane include the Wells Fargo Center downtown, at 601 W. First; Trent Plaza, in Spokane Valley; and a 54-acre site where it plans to develop an industrial park near Spokane International Airport. The company also owns a downtown parking lot, at 153 S. Wall, where it had planned to build a mixed-use tower. Prium now says, though, that it has shelved that project.
