D FORM A (DFA)

Architecture in Manhattan isn’t just about glass towers and steel skeletons—it’s a quiet conversation between space and the people who move through it. D FORM A (DFA) sits above the sidewalk at 866 6th Ave Fl 2, New York, NY 10001, where the hum of Midtown filters up through the windows. The firm handles everything from zoning sketches to full building permits, turning regulatory hurdles into clean lines and usable rooms. If you’re ready to break ground or just need a variance approved, dial (212) 683-4890 and set up a walk-through.

Most projects here start with a handshake over site photos and a stack of DOB forms. DFA specializes in residential renovations, commercial fit-outs, and the occasional historic facade restoration—each set of drawings tailored to the block’s rhythm. The second-floor office is easy to miss if you’re rushing past the delis and shoe-shine stands, but the address is right between 30th and 31st, above a bank branch that still has a neon sign from the eighties.

Planning a visit? Pull up directions before you leave—Sixth Avenue traffic can swallow an hour if you’re not watching the light cycles. Once you’re inside the building, take the elevator to the second floor and look for the frosted-glass door with the black lettering. It’s the kind of place where a single phone call turns a napkin sketch into a set of stamped blueprints.
