Sales have launched at 108 Chambers Street, a ground-up condominium project in Tribeca. Designed by Woods Bagot Architects and developed by Greystone Development, the building will contain eight full-floor residences and one- to three- bedroom homes that begin at $2.95 million. Ryan Serhant of The Serhant Team is in charge of sales and marketing for the reinforced concrete structure, which is now almost completely enclosed. The site will yield about 3,451 square feet of retail space that will occupy the first two floors and around 11,300 square feet of residential space above.
