Brooklyn architect aims for “overall conservation”

In an effort to be eco-friendly, Dumbo-based architect Roy Leone reuses building parts in his designs. For a brownstone Leone is renovating on Cranberry Street in Brooklyn Heights, he is using wood already in the house to make new stairs, and he is also creating a green roof, which will be covered with vegetation. Leone gives away materials that cannot be reused instead of throwing them out as part of an “overall conservation” philosophy.
