To the south-west is an area of green belt land, crossed by Pymmes Brook and leading down to New Southgate Cemetery; an adjacent road, Whitehouse Way, provided the backdrop to scenes from Mike Leigh’s film Secrets and Lies.

[3] The name is Anglo-Saxon, probably deriving from 'hawe's ege' referring to the Old English 'hawe' and the boundary (edge) of the Southaw wood.

The area was variously named as Huzeog, Hossegge, Huzeseg, Hwzeseg, Ousage, Ouzage, Owsage and Ussage.

A new Osidge House was built by 1808 and later occupied by the Lambert and Bosanquet/Bevan families, being purchased by Jacob Bosanquet's nephew Augustus in 1834[5] and then inherited by his widow, David Bevan's eldest child Louisa.

[11] Osidge was then given formal status as an electoral ward covering an expanded area bounded by Pymmes Brook, Oakhill and the Southgate border,[12] and in 1965 the district was transferred to the London Borough of Barnet.

[22] The school celebrated its 80th anniversary in 2016;[23] former alumni include Alan Coren, Rachel Stevens and Dan Gillespie Sells.

[26] The Club hosted live music in the 1980s–1990s, including the debut performance of Barnet band Omega Tribe in 1981.

In addition, Osidge House – for centuries the most prominent dwelling in the district – has main access from Chase Side, which formed part of the border of Edmonton Hundred, Middlesex, with Southgate as its nearest village.
