Did you ever see a deal that made you say, “Am I reading this right?” Well.. We’re excited to announce an opportunity to sublease space in Buffalo’s hottest building at $10 per square foot. The Giambra Team is excited to present a unique opportunity at the bustling Seneca One building, which has become the beating heart of mixed-use activity in downtown Buffalo. A former tenant is subleasing an entire floor with panoramic views of Western New York for $10 per square foot. The sublease covers floor 25 at Seneca One and is available until July 31st, 2026. The tenant is willing to consider subdividing the floor into smaller offices to accommodate the needs of potential tenants. There is no other local space that can compete with the location and price of this deal, let alone the lengthy three-year duration of the sublease. This is the perfect opportunity for a growing business that wants to be in the center of the action in downtown Buffalo, rubbing elbows with people working at M&T Bank’s signature technology campus, AML RightSource, Highmark and the startups at 43North. One of the floors is certified for the Start-Up NY tax incentives program. Seneca One has become a symbol of Buffalo’s resurgence under developer Douglas Jemal, who had the vision to turn the formerly vacant building into a vibrant live-work-play campus. The building is adjacent to Canalside, KeyBank Center and the Cobblestone District and sits on an NFTA Metro Rail line, providing seamless and car-free commutes to the medical campus, North Buffalo and UB North. The building also features over 100 apartments, numerous amenities such as a brewery, a locally-owned coffee roastery, a fitness center, a pet daycare facility and more. Its iconic lobby is attached to a 250-seat auditorium with a constant stream of events, many of them associated with Buffalo’s emerging innovation economy. The offices for lease are extremely private, with a badging system and 24/7 security separating the public and private parts of the building. The floors are move-in ready for a tenant that wants to take the entire 37,200 square feet, just one of the floors or a subdivided section of one of the floors. The elevators open directly to each floor, and they have high-quality kitchens and their own bathrooms. Enclosed parking spaces at an adjoining ramp are available at a price of $75 per space. Seneca One, which is Buffalo’s tallest building, has gone from completely empty to almost fully-leased in just five years. It is a special place, where inhabitants can look down and watch a Buffalo Bisons game, bring their kids on July 4 and watch 100 different fireworks shows or gaze at another country across the glittering Niagara River.The businesses that have moved into the building in recent years aren’t just looking for new offices. They are connecting their success with the momentum in the broader community, where a new era of investment is driving neighborhood revitalization, regional pride and a marked uptick in local entrepreneurship. This is an opportunity for a company that wants to feel that energy, and to make their own mark on Buffalo’s renaissance.
