Hotel 1000

Seattle, Washington








Hotel 1000 is a preeminent downtown Seattle hotel and residential address. Featuring ten stories of luxury hotels in the lower levels with eleven stories of residential condominiums above, the project also includes vehicle elevators at the parking levels in lieu of ramps for optimum parking efficiency.

The structure is framed with cast-in-place concrete, using state-of-the-art ductile shearwalls and hybrid slabs. Between the hotel and parking structure, offset columns were used to eliminate transfer beams. The columns are tilted over a distance of three floors so that additional depth for transfers was unnecessary.

The slab system incorporates a thickened drop head around the shearwall core, which eliminated internal columns and the need for deep transfer beams. By designing the entire shearcore as though it were a large vertical column, and by including a thickened drophead around the core, slab spans were increased to nearly 40 feet.
