This two-story addition to a row home in Federal Hill was completed by Greenleaf Craftsmen and features a light filled cantilevered second floor primary suite and first floor kitchen and dining room. Ziger Snead Architects designed the space to capture the maximum amount of natural light through clerestory windows which is filtered through an open wall concept, glass floor, and interior glass partitions. Historic elements of the house were preserved which qualified the house and renovation for CHAP credits.
