Arctangent Architecture + Design PLLC

The Financial District’s high-rise pulse quickens just south of City Hall. Arctangent Architecture + Design PLLC occupies the 18th floor of 55 Broad Street — an address where corporate towers meet the open sky. The firm quietly occupies a niche between raw structure and lived experience, translating programs into spaces that don’t announce themselves but simply work. Conceptual planning, feasibility studies, and code analysis anchor their workload; schematic design and construction documentation follow. They also coordinate bidding and administer contracts, bridging gaps between idea and occupancy. Residential alterations appear alongside corporate interiors, and each project is treated as a discrete puzzle rather than a template. The tower’s glass façade reflects the same skyline the team measures in metrics and zoning envelopes. Reach the office by dialing (212) 689-2688 — practical when you need to confirm a site visit or drop off drawings. A quick elevator ride saves the walk up from Bowling Green; the elevator banks discharge you one flight above the building directory. Find the route yourself — or let maps guide you here: directions to 55 Broad Street.
