Work on the 1805 Georgian-style house in Bermuda continues as landscaping on the south court begins, the veranda is framed and the second-floor walls are completed. Inside, the heating-cooling system is installed. Meanwhile, homeowner Andrea Dismont shows off an 1884 gold sovereign found under the dining-room floor, and host Kevin O'Connor tours Bermuda's Royal Naval Shipyard. On “Ask This Old House,” projects include installing track lighting in a condo kitchen and quieting noisy baseboard heating.
