3031 Western Ave

Elliott Bay Tower

Elliott Bay Tower is RexModular's flagship development — a 13-story, 120-unit luxury multifamily building on Seattle's waterfront, steps from the Olympic Sculpture Park. The site at 3031 Western Avenue was acquired in March 2026, and the project represents the first full-scale implementation of the Rex modular system.

This is our proof of concept. Every decision made in developing the Rex system — structural, mechanical, envelope, factory logistics — gets validated here. Successful delivery at Elliott Bay Tower will establish the repeatable framework we intend to deploy across the Seattle and Bellevue market at scale.
