A major expansion and renovation of Atlantic Station, the mixed-use retail, office and residential development in West Midtown, has begun.

Barricades are up as demolition begins to make way for a slate of new buildings and tenants, as well as a reimagining of the greenspace called Central Park.

Three brand new buildings, including a new Hobnob Neighborhood Tavern and two new 3,000 square-foot retail buildings for retail and restaurant space that will also house the newly renovated concierge facility and a private event space overlooking the park.

Central Park will be expanded to almost double its current size and include a new interactive water feature, shade canopies, and a giant LED video screen for the summer movie series.

Hines, the international real estate and investment group that operates Atlantic Station, said in a media statement that the changes being made over the next 18 months will fulfill the project’s overall vision.

The news comes on the heels of recent announcements about the in-progress construction of: two new office buildings, Atlantic Yards and T3 West Midtown; a new Embassy Suites Hotel; a 300+ unit apartment building by AMLI; and the remodeling of numerous retail spaces and new retail (Forever 21, Bowlero, an expanded H&M) and restaurant tenants (Naan Stop, Poke Bar, Pho 24 and Gyu-Kaku.
