Dating back to the 13th Century, a manor house is recorded at Cams Estate. In the eighteenth century, General John Carnac, a senior official of the East India Company, had most of the current house designed by Jacob LeRoux, to create a spacious mansion with a classically pedimented facade and grand south-facing rooms looking over Fareham creek.
In 1781 the Delmé family moved from Titchfield Abbey to occupy the mansion and then spent a small fortune on part-rebuilding and enlarging the house. This superb mansion was known locally as Cams Hall and remained in the hands of the Delmé Family for over 100 years.
Ownership passed to Montague Foster in the 19th century. It later had various uses, including a period under the Admiralty in World War II.
During the 1950s, a caravan park was started and the land was farmed by the Hill Family. This is the source of the "Cams Hill" Estate title. However, the Estate soon fell into disrepair after the then owner, Charles Church, was killed in a plane crash.
In the early 1990s, Strand Harbour Securities began a period of renovation. This included repairs to the Manor House, the Home Farm and Walled Garden, and also the sale of a portion of the estate for the construction of a golf course.
In 1995 a modern office block - "Delmé Place" - was built with many design references to the original house including two rotundas and an obvious nominal nod to the estate's historic owners.
In 1998 it was proposed as a landing point for the Project Oxygen (Global_Fibre_Link) causing significant investment from local business and the council to promote the estate.
In 2001 a future office park was added called Carnac Court (again a reference to the Estate's past).
