Seattle House Opens Pre-Leasing for Massive 1,131-Unit Luxury Rental Project
Connect CRE reports that Seattle House, a 1,131-unit luxury rental community at 2340 6th Avenue in Seattle's Denny Triangle, has opened pre-leasing ahead of a fall opening.

The delivery concentrates one of the largest single blocks of new Class A rental inventory to reach downtown Seattle in the current cycle. Configurations span studios through two-bedrooms, with more than 50,000 square feet of indoor and outdoor amenity space.
Supply concentration
The unit count — 1,131 — is the binding variable for the submarket. A single project at this scale shifts the local absorption denominator for the quarter across Denny Triangle, a neighborhood already absorbing competing new-construction deliveries. The unit mix covers the core downtown leasing surface: studios for single occupants, one-bedrooms for compact households, two-bedrooms for shared occupancy. Three-bedroom configurations are not part of this delivery, leaving that segment to be served by competing inventory in the surrounding area.
Location and product
The property sits at 2340 6th Avenue, two blocks from the Amazon Spheres and within walking distance of South Lake Union, downtown Seattle, Pike Place Market, the waterfront, and the city's expanding transit network. Arcadis IBI Group designed the project with a contemporary Pacific Northwest aesthetic — natural materials, abundant daylight, and seamless indoor-outdoor connections throughout the building.
The amenity base — more than 50,000 square feet of indoor and outdoor space — sets the comparable benchmark against competing new construction in the immediate area. "Seattle House was designed around how people live in the city today, moving between home, work, wellness, and everything downtown has to offer," said Nathan Leible, General Manager of Seattle House. The tenant profile the property targets overlaps with the South Lake Union workforce and downtown commuters served by neighboring Class A product.
What to track
Pre-lease absorption over the first 60 days will set the pricing reference for competing Class A inventory in the submarket. A high absorption pace indicates demand absorbs the 1,131-unit addition without concession expansion. A slower pace indicates landlord-side concessions widen on competing inventory as the fall opening completes. Watch the occupancy print from Seattle House itself once deliveries complete; the read-through into Denny Triangle and South Lake Union rents follows directly from this single delivery.
