On his lands in March Township, a settlement once divided between military gentlemen along the shore and Irish immigrants farther inland, 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. There were seven small cannons facing the river. Pinhey, who continued to prosper as a politician and insurance broker, named the estate, Horaceville, after his oldest son Horace. Horace was to be the heir to the estate, in accordance with British aristocratic tradition.
