Located in the Flatiron district of Manhattan, Ryall Porter Sheridan Architects has an idealistic mission: the firm specializes in green projects and offers associates "an architectural/travel research stipend as a means for encouraging future professional education." Projects range from a sound recording studio in rural Brattleboro, Vermont, to a loft in SoHo, spanning the architectural spectrum. Below are a few of our favorites from the firm's portfolio; photos via Ryall Porter Sheridan (many by photographer Ty Cole, whose site is well worth a visit).
