In the 1830s, he built a grand house which still stands to this day in Horningsea Park Drive and is listed on the Register of the National Estate.

The house was at some stage home to Count Strzelecki, the Polish-born explorer who named Mount Kosciuszko.

The suburb was part of neighbouring Hoxton Park and largely farmland until 1996 when Long Homes subdivided the area for housing and Liverpool Council named it after Moore's estate.

At the southern edge are the Trash and Treasure markets, a familiar landmark to passers by on Camden Valley Way.
