From Wikipedia: "Wanstead House was a mansion built to replace the earlier Wanstead Hall. It was commissioned in 1715, completed in 1722 and demolished in 1825. Its gardens now form the municipal Wanstead Park in the London borough of Redbridge." Below, many bits and pieces from the estate can still be found.

The Wanstead design shortly preceded the design of Burlington House, London, for Richard Boyle, 1st Earl of Burlington, an early proponent of the neo-Palladian style. William Kent (1685-1748) was in charge of the interiors of both residences. below, a Hogarth painting of the interior, The Assembly at Wanstead House, 1728-32, now in the Philadelphia Museum of Art.
It was the décor above that William decided to update after he gained control of Catherine's fortune, just one of his myriad extravagances, including gambling and adultery, which left the couple penniless and needing to flee Britain with their children by 1823.
Heartbroken and suffering from illness, perhaps a venereal disease her husband gave her, Catherine was successful in getting her children and herself back to England, where she made certain her children were protected from William before she died in 1825. No surprise to Regency aficionados, Arthur Wellesley, 1st Duke of Wellington, William's uncle, guaranteed the control of the children remained with Catherine's sisters, Dora and Emma, though none ever fully recovered from their abusive father's influence.
