This building had been a sweat shop and still looked the part. Its small windows were far apart, and its interior was dark and cluttered. Despite a tiny budget, the Brooklyn architects turned the ugly cave into airy live/work design studios. Cutting giant new windows into the facades changed them from messy to monumental. The once dark interiors now have expansive views of Greenwood Cemetery and the harbor beyond. And broad squares of sunlight now wash over floors of polished concrete and maple plywood sliced into planks.
