Furness House £- 4 million-plus

Owned by Patrick Guinness of the brewing family, and his wife Louise, Furness House, an 18th century mansion set on 34 acres of parkland near Naas in Co Kildare, is on the market through Hamilton Osborne King, having been withdrawn from auction earlier in the year. The pre-auction guide price was £4 million but the agents are now seeking offers over that figure. Extensively refurbished, this 15,000 sq ft house has two wings, nine bedrooms and four reception rooms.
