Cushman & Wakefield sold 10 Post Office Sq. to a venture between GreenOak Capital and Synergy Investments for $143 million. The Cushman & Wakefield team, led by president Robert Griffin, vice chairman Edward Maher and executive director Matt Pullen, oversaw the transaction of the signature 13-story office building on behalf of Soundport Capital and acquired the buyer. Totaling 445,000 s/f across two interconnected, mid-rise towers, 10 Post Office Sq. is a trophy office asset overlooking the Norman B. Leventhal Park, a 1.7-acre "garden in the city" featuring an open lawn, perennial gardens, decorative water fountains and 1,400-vehicle below-grade parking garage. 10 Post Office Sq. offers an exceptional blend of stability and upside, 82% leased to a diverse tenant roster anchored by the global headquarters of Boston Private Financial Holdings, which has called the property home since 1987. "10 Post Office Square has a distinctive history, well recognized as one of Boston's finest office restorations and boasting more than $17 million in capital improvements in the last seven years," said Maher. "It offers an iconic and commanding street presence in the heart of downtown Boston directly across from Post Office Sq., a unique outdoor space that serves as the city's 'go-to' gathering point, making it one of the area's top business addresses."
