Most CORE clients (and viewers of “Selling New York“) are familiar with our storefront office at 127 Seventh Avenue in Chelsea, but many have never seen our Flatiron District headquarters at 104 Fith Avenue, which opened last year. So for our pre-Labor Day Photo of the Week, we thought we’d offer this glimpse of where many CORE agents and executives actually do their labor. What can we say? We’re suckers for a good tie-in. The 5th Ave. office is a bit more private than than the glassy storefront in Chelsea, but no less thought out when it comes to modern interior design. Like our new digs?
