Marx Realty, a New York-based owner, developer and manager of office, retail and multifamily property across the United States, announced that investment advisory firm Helix Partners Management has signed a five-year, 7,000-square-foot lease on the eighth floor at 545 Madison Ave. The firm is relocating from 399 Park Ave.

“We are excited to have Helix Partners join the impressive lineup of top-tier financial companies at 545 Madison,” said Marx Realty President and CEO Craig Deitelzweig. “This lease comes just weeks after we unveiled the Leonard Lounge, a spacious lounge on the same floor complete with a café, fireplace, landscaped terrace and boardroom.”

Helix Partners was represented by Greg Maurer-Hollaender of CBRE, while a Cushman & Wakefield team led by Tara Stacom represented Marx Realty.

Marx Realty recently completed a $24 million renovation of the property that went beyond superficial changes, essentially creating a home-away-from-home experience in the office. The one-of-a-kind strategy set a new industry standard, catering to the demand for high-quality office spaces. As a result, Marx Realty has achieved higher occupancy rates, increased asking rents and attracted a prestigious tenant mix.

“Helix Partners was particularly attracted to the well-appointed pre-built suites at 545 Madison as well as the elegant and elevated environment that the property offers to their employees and guests,” added Deitelzweig.

The recently unveiled Leonard Lounge represents the culmination of 545 Madison’s top-to-bottom renovation. Spanning 7,000 square feet, this stunning space is composed of three distinct areas: a café, a 2,000-square-foot landscaped terrace and a 40-seat boardroom. The Leonard Lounge is reminiscent of a members-only club and was named after Leonard Marx, the founder of Marx Realty. It boasts a variety of elegant features, including a ceiling-suspended fireplace surrounded by plush velvet seating, which gives the lounge a rare, sophisticated ambiance not often found in traditional office settings. Whether users are looking for a bespoke workspace outside of the usual office environment or a cozy nook to unwind with a cocktail after a long day, the Leonard Lounge provides the perfect respite.
