GF55 Architects

Based in New York, GF55 Architects articulates multi-family residential and high-rise mixed-use buildings through sharp knife-edge prows, offset grid facades, and exposed structural elements integrated into planted urban podiums. This body of work provides a clear reference when breaking down large housing volumes, offering precedents for detailing projecting metal shadow fins, designing public street-to-terrace transitions, and floating glowing upper clerestories over darker masonry bases.

241 Halstead

A multi-family residential building precedent demonstrating how to handle a sloping urban site with a raised terrace, monumental outdoor stair, and integrated ground-level parking.

What we like about this project
The prominent exterior stair cuts diagonally into a planted retaining wall leading directly to the upper terrace.
