The house at 24 Sussex Drive (originally Sussex Street) was commissioned in 1866 by Joseph Merrill Currier, a Member of Parliament, as a wedding gift for his fiancee, Hannah Wright. He named it Gorffwysfa, a Welsh word meaning “place of rest.”

Its ownership by the government involved a legal fight

In the 1940s, foreign governments were buying land near 24 Sussex for embassy space, and the government feared this property, with its commanding views and choice location, might be next. So in 1943 it served an eviction notice to the home’s occupant, former MP Gordon Edwards.

But he didn’t want to leave, and spent the last few years of his life fighting the order. The government offered $125,000 compensation for the house. Edwards demanded $251,000. In 1946 a court eventually settled on $140,000 plus $7,319 in legal costs. Nevertheless, Edwards stayed on until he died later that year.
