The law firm Schwartz Sladkus Reich Greenberg Atlas will expand to 33,115 square feet in a move to 444 Madison Ave. between East 49th and 50th streets.

Under a 12-year lease, the attorneys will occupy a portion of the fifth floor and the entire sixth floor, which will be built out by the Westbrook Partners ownership.

In the last three years, the firm has grown from 33 to 44 lawyers in real estate, litigation, health care, trusts and estates, corporate, intellectual property, nonprofits and matrimonial law.

The firm is currently located in 22,000 square feet at 270 Madison Ave. on the northwest corner of East 39th Street, which is south of Grand Central Terminal.

Its new Midtown building was previously known for tenants Newsweek and later New York magazine, but the 42-story tower’s signage now lists Burberry as a key tenant.

“The lobby was recently redone, and there is space on first floor and lower level that is being turned into an amenity,” noted SSRGA partner Steven Sladkus.

His partner Jeffrey Schwartz says the space will have an open feeling, with a layout that has perimeter offices for all the lawyers and views overlooking St. Patrick’s Cathedral. “Open plan doesn’t really work for law firms,” Schwartz added.

SSRGA was represented by Mitchell Konsker, vice chairman of JLL, along with colleagues David Dusek and Harley Dalton.

The building owner, an affiliate of Westbrook Partners, was repped by a CBRE team led by Vice Chairman Paul Amrich, with Patrice Meagher and Meghan Allen. Sources said the asking rents are in the $60 per square foot area.
