Edes House, at 2929 N Street, N.W., is a very large brick townhouse In Georgetown. It was built in 1908 with proceeds from the will of Margaret Edes, as a residence for poor widowed women. It lasted as a retirement home until 1998, when the directors of the home found that they could not find enough retired tenants. They sold it for $825,000 to developers Walter Lynch and Davis Camalier, who remodeled it into a residence. After their extensive renovations, they sold it to billionaire Roger Sant for $4.2 million.
