The 90,000 s/f property at 330 East 63rd St. occupies a 17,500 s/f footprint. Eastern Consolidated director Aliza Avital represented the seller, 63rd East Side Realty LLC, and Avital together with Alan Miller, senior director, procured the buyer. "It's rare for the seller, a local real estate family, to sell one of their buildings,"said, Avital.º"But the market is at an all-time high, so not surprisingly it made sense to maximize their investment at this time." Miller said, "Stonehenge is thrilled with this new acquisition and intends to upgrade and renovate the property, and gradually raise rental rates. The majority of the apartments,37 studios, 42 one-bedrooms, and 14-two bedrooms, are rent-stabilized." Average apartment sizes at 330 East 63rd St. are over 750 s/f.
