MANHATTAN — Starbucks will open a massive 20,000-square foot "roastery" in Chelsea in 2018, the company announced Tuesday.

The new roastery will be located at 61 Ninth Ave. and will be only the second of its kind in the nation, following the model of the Starbucks Reserve Roastery and Tasting Room that opened in Seattle, Wash. two years ago.

A spokeswoman said the store will be the largest of any Starbucks store in the world, Fortune reported.

“Our Seattle Roastery experience created something that had never been done before, transforming a retail environment into something far beyond just a coffeeshop and into the single best retail experience of any kind,” said Howard Schultz, CEO of Starbucks in a statement.

The new building to be built a block south of Chelsea Market, set to be designed by New York City-based architect Rafael Viñoly, will allow customers to interact with the company's roasters and baristas to understand the process from sourcing to brewing coffee, Starbucks said.

“In New York, we want to take elements from what we originally created and build something even bigger and bolder.”

The building housing the roastery, which is expected to be completed in 2017, will be approximately 170,000 square feet and 9 stories tall.
