Whilst Adsdean (sometimes shown as Adsden or Ashdean) was significant enough to be shown on maps of 1724, 1778, and 1795, the principal house, gardens and parkland were not created until some time between 1840 and 1880. The evidence of this is an estate map of 1840, when the land was in the ownership of Mr John Scardeville, then only Adsdean Farm existed surrounded by fields and some woodland blocks along the north-west boundary. By the 1870-1880 Ordnance Survey map (surveyed 1859, 1867 and 1875), Ashdean Park, House and Farm is shown, as well as the two lodge houses, East Lodge (formally called Chichester Lodge) at the entrance to the drive through the park to the house and West Lodge (formally Havant Lodge) by the main road entrance leading to a tree-lined avenue to the house.

The house is reputedly to have been built by 3rd Duke of Richmond to a design by Charles Dorrien. Certainly the estate was part of the Goodwood estate from 1800.

In Sept 1898, Adsdean Estate, which was let to Mrs Kincaid Smith, was put up for sale. It is thought Adsdean was bought by the Tennant brewing family, who were responsible for planting the cedar trees. From around 1925 to 1946 the house was let to Mountbatten, who built a nine hole golf course and polo field in the park. In 1954 part of the original house demolished and in 1970 the house, stable block and outbuildings were sold off in lots to form five separate residential units.

The 1898 sale particulars describe the site as, "... the well-known country seat distinguished as Adsdean Park ...The mansion occupies a well-chosen site 250 feet above sea level, effectually (sic) screened from the north and east by the rising ground clothed with thick plantations, and commands views which for extent, beauty and interest are difficult to equal. They embrace both land and sea - the English Channel with a fine stretch of coast line, Isle of Wight, Portsmouth, etc., being distinctly visible. As seen from the Chichester Road, nestled amidst rich plantations, it presents a pleasing picture and an ideal situation...approached by two long carriage drives, one through a charming avenue of plantations and the other winding through the park. They are each protected at the entrance by a superior lodge...the extensive well-wooded park, falls away in pleasing undulation in front of the mansion, allowing of a pretty view of the drive traversing it." Whilst Adsdean House is now somewhat reduced in size from the original, the 1898 description of the site still runs true. Only the parkland is missing.
