All but the finishing touches have been completed as tenants begin to take up residence in the 308,580-sf building located above the Washington State Convention & Trade Center. The first four floors of the building are dedicated for an expansion of the center. The first tenants to occupy offices in One Convention Place is Medisystems, a medical device company; Lee Smart Cook Martin & Patterson PS, a law firm; and Guy Carpenter & Co., a New York-based reinsurance firm.

Other tenants include InterNap Network Services Inc., Sprint Communications, law firm Betts Patterson & Mines PS, accounting firm Grant Thornton LLP and Oles Morrison Rinker & Baker LLP, another law firm. InterNap, with seven floors, is the tower's largest lessee. Gross rental rates on the Downtown property are listed at $40 per sf to $46 per sf.

The property is the jewel in the Northwest crown of Dallas-based developer Trammel Crow Co. One Convention Place is the first new office tower in the central business district since Wright Runstad & Co. completed the 22-story, 422,000-sf Second & Seneca Building in 1991. The downturn of the early 1990s thwarted major office developments in the CBD for several years.
