Summary
Park 53, a 19-story boutique office property at 45 East 53rd Street in Midtown Manhattan, has added three new tenants occupying space across three floors totaling 19,145 square feet, Commercial Observer reported. The largest transaction was a 7,145-square-foot lease by hedge fund Forest Avenue Capital, which will occupy the seventh floor after relocating from 9 West 57th Street.

JLL's Mitchell Konsker, Benjamin Bass, Alexander Chudnoff, Greg Wang and Thomas Swartz represented building owners ZG Capital Partners and Rialto Capital Management across all three transactions. Konsker said the activity reflects continued demand along the Park Avenue corridor from firms that prioritize location and office quality, noting that the tenants are moving from established Midtown addresses to a more boutique environment in the Plaza District.
