Hollam House, overlooking Titchfield on the south side of the river, was built in 1802 for a Royal Navy captain, James Anderson. Although just completed in the 19th century it is characteristic of late 18th century building. Pevsner has almost nothing to say about it, so I don’t think he found it in any way remarkable. The origin of the name Hollam House is obscure.
In 1957 it was developed as a care home but sometime later it was remodelled and restored to a spacious mansion. In recent years it gained some notoriety during the MP’s expenses scandal because it was owned by Sir Peter Viggers, the MP for Gosport, who commissioned a very expensive duck house for the pond at Hollam House.
He subsequently sold the house.
