Lucerne, Hamden, Connecticut:
Built in 1906, this castle-like mansion at 20 Davis Street was designed by the architects Brown and Von Beren. The home was constructed for Frederick D. Grave, a German immigrant who arrived in America in 1861. Grave founded a New Haven-based cigar company in 1884 which became known as F.D. Grave & Son. Nowadays, the mansion is home to the architectural offices of Kevin Roche, John Dinkeloo and Associates, who have restored the property to its former grandeur.
