A classic 1911 Georgetown house, originally owned by Washington industrialist and inventor Herman Hollerith, was originally built for his daughter who could live there as long as she liked – if she never married. When the new homeowners came into possession of the property, it was clear that the Hollerith house needed some expert care. A complete gut renovation included a new kitchen and a glass conservatory acting as a sunroom that looks out on the tranquil back garden.
