Earlier Houses: An earlier Tudor manor house was demolished in 1719, when the core of the current house was built.

House & Family History: Known as Armholt Wood in the 14th century, Arnos Grove was owned by the nuns of Clerkenwell until the Dissolution of the Monasteries in the 16th century, after which a private house was built on the Estate. This house was purchased by James Colebrook in the early 18th century; he demolished the Tudor house in 1719 and replaced it with the current house, which he named Arnolds. Later in the 18th century Sir William Mayne purchased the Estate and renamed it Arnos Grove. In 1777 Arnos Grove was purchased by Isaac Walker of the Walkers of the Taylor Walker brewing family; the Walker family remained seated here until 1918. In 1928 Arnos Grove was sold to North Metropolitan Electricity Supply Company, who enlarged the House in 1929 and 1935. Legal & General purchased Arnos Grove in 1975 and renamed it Southgate House. In 1998 Arnos Grove was divided and converted into a residential care home and luxury apartments.

Garden & Outbuildings: The 44-acre Arnos Park is a remnant of the Arnos Grove Estate. It was opened as a public park in 1928, after having been purchased by Southgate Council.
