We converted this multi-family townhouse into a multi-story art gallery and office by stripping the existing building back to the shell and creating four floors of gallery space, with a top floor kitchen and cellar storage. Construction included the stabilization of a rear two-story addition; all new roofing and skylights; new building systems including mechanical, electrical and fire protection and passenger elevator. We installed a new oak stair with custom steel balusters and oak handrail from ground to top floor.
