SEATTLE—Mack Urban has unveiled its design proposal for a 43-story, 430-unit residential apartment tower located at 1001 John Street in South Lake Union. The tower will include 2800 square feet of retail along Terry Avenue North and 300 underground parking stalls.

With a 53' foot drop between John Street and Terry Avenue North, the site has been identified in city planning documents as one of several locations that would benefit from a public hill climb assist. “What many would see as a challenge we saw as an opportunity,” said Paul Keller, founding principal and CEO of Mack Urban. “The topography enables us to design a tower with a strong public connection and view point amenity.”

Currently there is no pedestrian connection between upper John Street and lower Terry Avenue N. Vacated in 1955, the land remains private property and is occupied by a five-story concrete warehouse. Mack Urban is proposing to site the new tower on the Southeast corner of the 18,570 square foot lot in order to voluntarily provide a public hill climb and view point plaza with territorial views of the Space Needle and Lake Union. The public plaza will be designed to connect with John Street and the Seattle Times park. The hill climb will also include a public elevator located to the north of the new residential tower.
