The 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, 220,000-square-foot office tower. The AMLI/MDI joint venture is developing the AMLI Arc residential tower. The glass-and-metal-panel residential tower will include 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 will 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 will include a private party room with an outdoor dining area for intimate gatherings, 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 and sweeping views of the Seattle skyline and Puget Sound, and a bicycle maintenance and storage area, and a pet spa. AMLI and MDI are targeting LEED Gold certification for the residential tower. Construction began last summer and is slated for completion in 2017.
