Building the tower
Developed by Martin Selig and designed by Chester L. Lindsey Architects, Columbia Center was built from 1982 and completed in 1985. It opened as Columbia Seafirst Center, named after Seafirst Bank.
A height limit
An earlier design of about 1,006 feet was too tall for the federal aviation rules that apply near Seattle–Tacoma International Airport. The tower rose instead to 76 storeys and 933 feet, still the tallest in Seattle and Washington state.
Glass and granite
Its three concave facades step back twice on the way up. The base is clad in Carnelian granite, and the tower in smoked glass, with some 8,800 windows.
