Douglas Development Corporation is redeveloping this 38-story tower into a mixed-use project featuring 115 residential apartments of all sizes, retail on the plaza and office space in the tower. The tower’s west annex wing will consist of 115 apartments, with a mixture of market-rate studio and one-bedroom rental units, as well as two-bedroom apartments. The 3.5-acre concrete plaza area and east annex, will be redeveloped into a 75,000-square-foot, multi-level retail mall, with a variety of outdoor seating.

Seneca One offers sophisticated, modern residences right in the heart of Downtown Buffalo. An SO apartment home means that you’ll have Canalside, Buffalo’s Theatre District, Key Bank Center, Sahlen’s Field, and Buffalo’s most popular dining destinations steps away! Additionally, the Seneca Metro Rail station is located directly in front of SO and will transport you to Allen Street and the Buffalo Niagara Medical Campus in minutes!

Boasting three stories of apartments of all sizes and a variety of unique floor plans available, Seneca One is the space you’ve been looking for but couldn’t yet find. That’s because it’s not a complex, it’s a community.

In addition to the residential offerings, Seneca One has more than 1,000,000 SF of commercial office space with over 300,000 SF currently available.

Retail space is also available at Seneca One. 1,900 SF, 4,000 SF, and 8,000 SF standalone spaces are available on the plaza level of the property while additional traditional storefront spaces are available within the main building.
