Today, The 88-acre (360,000 m2) heritage site is owned and operated by the City of Ottawa and Pinhey's home serves as a museum.
For his services as King's messenger during the Napoleonic Wars, he received a 1000 acres land grant on the Ottawa River.
On his lands in March Township, a settlement once divided between military gentlemen along the shore and Irish immigrants farther inland,[3] he built a grist mill, homes for employees.
On the hill overlooking the sheltered harbor of Pinhey's Point, he built a small two storey log house covered in clapboard.
Pinhey, who continued to prosper as a politician and insurance broker, named the estate, Horaceville, after his oldest son Horace.
[5] Pinhey built a large stone manor house on top of the hill in three different stages, in a symmetrical Georgian fashion.
The stone house, which was completed 1822–1825, consisted of a large parlour and three small bedrooms (servants quarters) on the second floor.
A south wing addition, completed in 1848–1849, consisted of Hamnett's Library, the pantry, the drawing room, several family bedrooms and a second floor indoor privy.
To give the appearance of more expensive woods, painted grain patterns were applied to plain pine floors and doors.
The Pinhey's Point Foundation was established in 1980 to preserve and develop the estate as a historic site and recreation area.
Since Kanata amalgamated in 2001, the City of Ottawa has owned, managed and maintained the site and has been responsible for the special events, programs, and daily interpretation.
Posters in the upstairs dining room, for example detail the restoration process the manor house underwent in 1990s, under architect Julian Smith.
The Hamnett Pinhey's library remains furnished in its later incarnation as a sitting room/dining room complete with a reproduction 1880s gown.
Although Pinhey Point has a bay which is popular and convenient for both day and overnight anchorage, people should not attempt to land at the site's small dock facilities in anything bigger than a dinghy or tender.
"On land granted to him for service in the Napoleonic Wars, Pinhey built a substantial estate comprising several log and stone structures.
