Office Space


The massive redevelopment of Seneca One offers the opportunity to be part of something very special.  For decades, the building has been a cornerstone of downtown Buffalo’s commercial real estate market.  After enduring years of change, the building is well-positioned to undergo a grand transformation as envisioned by developer Douglas Development. 

Take your business to new heights!  Office and retail opportunities at Seneca One are truly unique.  Large, open floorplates void of columns, 360 degree views of the city and Lake Erie shoreline, garage parking, controlled access, lively bars, restaurants, food hall, fitness center, 200+ seat auditorium, open air plaza spaces and a host of other amenities offer tenants and their employees a lifestyle and a business address.   


A destination for the most exciting businesses in the region, Seneca One is dedicated to creating a thriving corporate culture that builds on the strengths of its tenants and promotes a collective drive to succeed.  Join startups, global tech companies, aspiring entrepreneurs, and creatives that call Seneca One home and invigorate this space. 

Opportunities for office users start at 6,000 square feet with full floors available totaling approximately 20,000 square feet. For full availability, floor plans and other details check in with Ciminelli Real Estate Corporation online by clicking the full listing here.
