In 1794, Prince Edward arrived to serve in Halifax as Commander-in-Chief of the King's forces in Nova Scotia and New Brunswick.

Prince Edward accepted, and had the residence renovated into a two-storey (likely Palladian architecture mansion)[2] and expanded, while also having the lands and gardens (with Chinese like pagodas) around the estate developed by a landscaper brought from England.

Now called the Prince's Lodge, it was here that Wentworth established the Rockingham Club in the former officer's barracks.

All that remains of the original estate is the music room (Rotunda) less a foot bridge spanning over railway line, which the Nova Scotia Government acquired in 1959.

It is a small, round music room that stands on a knoll overlooking the Bedford Basin.
