NEW YORK CITY-South of Midtown, approaching Tenth and Eleventh Avenues in Chelsea, a line of warehouses and aging office buildings once lined the blocks near the Hudson River. Now, a crop of former class C buildings have been transformed into a top-tier destination for creative and high-tech tenants.

After a successful repositioning effort, commercial real estate manager Pembrook Capital Management LLC has contracted to sell a three-building office complex at 511 W. 25^th St. to an affiliate of the Related Cos. for $93 million. The properties, totaling 195,000 square feet, abut the High Line Park, which Pembrook’s president and CEO Stuart J. Boesky says improved sales efforts.

“It has certainly helped increase the visibility and the value of the building,” Boesky tells GlobeSt.com. “Right now it is branded as one of the more desirable creative use buildings in New York City. Being next to an elevated park is a really nice amenity for us.”
