Horizon House, a nonprofit, independent living senior community in Seattle plans to add a 33-story residential tower at its First Hill campus. The 202-unit tower will replace an existing 1980s wing and join three other buildings on the 900 University Street site. This is the latest senior housing project for the neighborhood which has many retirement communities near major medical facilities.
Mithun of Seattle serves as architect while Andersen Construction is design-builder of this nearly 900,000 square foot expansion project. The new high rise will measure 500,000 square feet with underground parking included in its plans. Westlake Consulting Group LLC acts as construction manager and Abbott Construction has been hired to do upgrades before construction begins late 2025 or early 2026 with completion set for 2029
