ALMI Arc Construction Project / SeattleWA
What happens when Mortenson becomes more than just your builder?
AMLI Arc is a 393-unit luxury apartment tower that shares a 509-stall underground parking garage and ground-floor retail space with Tilt49, an 11-story, 300,000 square foot office tower. The glass-and-metal-panel residential tower includes amenity spaces on the 12th and 41st floors, with views of the Seattle skyline and – on a clear day – Mount Rainier, Puget Sound, Lake Union and the Olympic Mountains. The apartments come in three varieties, ranging from units with exposed concrete ceilings and industrial-inspired interior design to luxury penthouses with condo-quality finishes. Amenities within the apartment tower include a private party room with an outdoor dining area for intimate gatherings, a chef’s kitchen for hosting larger parties, an expansive fitness center and yoga studio, a media room, conference rooms and co-working spaces, a large rooftop deck with outdoor grilling areas, bicycle maintenance and storage area, and a pet spa.
