Just outside the borders of Green Park is Spencer House, completed in the Palladian style in 1766 for the first Earl Spencer, an ancestor of the late Princess Diana. The Spencers moved out in 1927 and their grand family home was used as an office, until Lord Rothschild stepped in and returned it to its former glory in 1987 with an £18-million restoration. Visits to the eight lavishly furnished state rooms designed by John Vardy and James "Athenian" Stuart are by guided tour only.
From April to October, weather permitting, the 18th-century garden is included at the end of the house tour and adds around 15 minutes.
