John Radcliffe, who was on good terms with Coulson, The house came into the ownership of the
Daughters of the Cross. It is now part of
St Philomena's Catholic High School for Girls. Fellowes then purchased Carshalton House, in 1715. But a legal issue on its title arose: Edward Carlton, a tobacco merchant, had been declared bankrupt. Carlton (or Carleton) owed money to the Crown, on his death in 1713. After the accession in 1714 of
George I of Great Britain, properties held by Carlton were granted to Fellowes, including a copper mill. The legal and tax position was rectified, for the properties that had come to Fellowes from Carlton, by a device suggested by
Sir William Scawen. It involved Thomas Scawen buying the house, and selling it on in 1716 to Fellowes. Fellowes had the Water Tower built there, at his seat, around 1721. Girouard calls it "The best surviving example of domestic water-architecture of this period". The engineer was Richard Cole. It had a
water-wheel, powered by a mill-stream under the tower coming from an artificial pond. Water was pumped both to the house and to a bathroom in the base of the tower. Above were an
orangery, saloon, robing room and a
long gallery. The battlements are an example of the
sham medievalism of the time, seen also at
Briggens House, built by Robert Chester, another South Sea Company director. At Carshalton House, Fellowes also employed the garden designer
Charles Bridgeman, and the nurseryman Joseph Carpenter of
Brompton Park. The master builder and sculptor Giles Dance worked there in 1720. The architect
Henry Joynes was there around 1720, perhaps being employed on the Water Tower. Christopher Blincoe, a plasterer, worked on the house in 1719–1720. Details of the furnishings were in the 1721 inventories of estates of South Sea Bubble figures. Mentioned were caffaw, a "rich silk cloth similar to damask", and culgee, a "figured Indian silk". The Painted Parlour at Carshalton House is by
Robert Robinson, a decorative painter and engraver who died in 1706. It therefore dates back to Edward Carlton's ownership. The Oak Parlour had an overmantel wooden carving of Fellowes's coat of arms. Fellowes added the third storey of the house. The Hermitage at Carshalton House may as a building date from Bridgeman's formal garden design for Fellowes. The name isn't attested until the 19th century. ==Later life and death==
