For the Brooklyn offices of Delson or Sherman Architects, a raw industrial space in Dumbo became a serene work space. To make the most of the two exposures and high ceilings, the architects ran the open office along the sunny window walls. The library, storage, and kitchen then shifted to the core. The crisply detailed furnishings boldly contrast with the loft’s rough concrete and exposed ducts. Simple black solar shades temper the glare. Cherry plywood cubbies, aligned with the window sills, provide handy storage while defining the spaces. Desks made of continuous black granite slabs run the length of the office and drop to the floor. Occasionally, the office also doubles as gallery space for selected artists.
