You can argue over the impact that Amazon is having on Seattle, especially in the Denny Triangle region, but you can't deny that it's coming and developers are thinking big. Case in point, the proposal at 2326 Sixth Avenue that just doubled in size from original plans. Earlier this year, Antioch University submitted plans for a 40-story residential/condo tower. Now, HB Management has confirmed they are buying the lot as well as an adjacent corner in order to build two 42-story towers with 830 apartments, 198 hotel rooms, 12,000 square feet of ground floor retail and 600 parking spaces. Why so big? The site is a skip and a jump from the spot where Amazon is currently planning two office towers and probably more. Developers are requesting an exception to the rule that requires a 60-foot separation between the two towers and they plan to improve and add space along Battery & Bell Streets along Sixth Ave. Antioch plans to move their campus to a yet-to-be-determined location.
