Howell Belanger Castelli Architects, P.C.

Howell Belanger Castelli Architects, P.C. sits above the city’s busiest corridors. An architectural practice with fine attention to cityscapes and volumes, it approaches each commission with direct problem-solving. Designs for institutional, residential, and commercial clients share an emphasis on spatial clarity, daylight logic, and material precision—each project hashed out in two dimensions before taking shape in three.

The studio operates from 122 W 27th St, 4th floor, New York, NY 10001, close to the Flatiron district’s light industry and art galleries. Getting here is easy by subway or bus; a short elevator ride delivers you to a contemporary office focused on the work before the welcome. If the building’s entrance feels utilitarian, it only signals what’s to come: measured drawings and clear clauses, not distractions.
