In March 1912, the bank purchased the Southeast corner of Dock and Holly Streets for $175,000. The site was occupied by several wooden buildings dating to the late 19th century including the Beck Hotel, built on the corner in 1888 by David Beck who would later build the adjoining theater. The parameters of the property were described in the local paper:
The property involved in the deal extends from Dock Street to the alley between Dock Street and Railroad Avenue, a distance of 125 feet, and is 110 feet deep.
The bank announced their plans to build a $200,000, 6 story brick and concrete building on the lot that would be one of the finest in the Northwest. The bank would occupy the ground floor corner of the building, a frontage of about 50 feet on Holly, while the rest of the building would contain offices above and retail stores on the ground floor. Demolition and then construction would begin by June of the same year.
The bank hired Bellingham architect F. Stanley Piper to design the building who in turn hired C.H. Beattie of Seattle as the general contractor. Work began at a quick pace and by February 1913, the concrete structure of the building was complete with laying of the brick facing about to begin. Each of the building's 124 rooms was to be equipped with hot and cold running water as well as access to the building's vacuum system. Other modern features would include two high-speed elevators and a mail chute.
The first two stories were clad with Wilkeson Sandstone with the upper four clad in light buff colored pressed brick. From the top of the fourth floor windows to the parapet line was clad with terra cotta.
The interior corridors featured terrazzo floors with panels and borders of Alaskan marble. The vestibule was adorned with an 11 foot high marble dado of Colorado Yeul while the columns in the vestibule were of genuine Italian Pavonazzo marble. Materials used in the banking room included Alaskan and Kasota marble, Honduran mahogany, and bronze Kalamine for doors.
By August 1913, the building was complete and tenants began to move including doctors, dentists and other professionals. The bank officially opened on December 1, 1913.
