Description

Mill Green possibly has medieval origins and was known as Cranmarsh in the C17th and later as Beddington Corner. It came within lands of Mitcham Common, but by 1895 was a separate entity and used for recreation, but since the 1990s it is once more managed by Mitcham Common Conservators. Today it is a triangular open space with areas of grass, mature and semi-mature perimeter trees including 3 mature hybrid black poplars in the south-west and a series of ditches and culverts that were linked to the Wandle River. A concrete channel runs through the Green known as the Beddington Carrier, which takes effluent from Beddington Sewage Treatment Works to the River Wandle.

Full description

In the C17th Mill Green was known as Cranmarsh, possibly a corruption of the Mitcham family called Cranmer. Ownership of the Green was in dispute between the Manors of Mitcham and Wallington until well into the C19th. Originally within the parish of Mitcham, it came under the civil parish of Wallington as a result of boundary revisions in the late C19th century. On the OS map of 1868, then known as Beddington Corner, it was shown as an ‘Old Site' as part of Mitcham Common, but by 1895 it was shown as a separate site, and was administered by trustees. It was used as a recreation ground. Up until the early 1990s Mill Green was managed by LB Sutton on behalf of the Mitcham Common Conservators, which had been established in 1891 as the legal custodians of Mitcham Common (q.v.) under the Metropolitan Commons (Mitcham) Supplemental Act 1891. The Conservators are drawn from the London Boroughs of Croydon, Merton and Sutton and the Corporation of the City of London. Since the 1990s Mill Green has been managed and regulated by the Conservators once more and was included in the Mitcham Common management plan that was adopted in 2007 after wide consultation. Proposals included possible ecological enhancements to Mill Green such as allowing additional areas of grassland to be managed as meadow and selective tree planting to improve the wildlife value although it was agreed that these suggestions should be explored further and in particular their likely impact on current usage of Mill Green. A landscape strategy in 2009 includes proposals to enhance Mill Green so that it and the neighbouring Beddington Farmlands formed a coherent gateway to Hackbridge, and also to re-engineer the river channel into a more natural environment. Now on two areas of Mill Green the mowing regime has been relaxed so that grass is maintained as a meadow throughout the spring and summer and mown again in the autumn in order to benefit plants and insects by providing a more suitable habitat.

Mitcham Garden Village is a small housing estate that was built in 1929-32, the half-timbered houses all of different design facing inwards around a keyhole-shaped close. It was set up by local benefactor Sir Isaac Wilson who lived in Mitcham and established a trust to build these two-storey houses for the elderly in what was once part of the land owned by the Cranmer family. The design was based on garden village principles then prevalent, with cottage style houses, each with its hedged front garden, set back behind the landscaped 'village green' and the whole enclave surrounded by informally landscaped open spaces.

Poulter Park is named after the co-donor Reginald Poulter. Although much remains of the original estate Bishopsford House, first shown on the OS map of 1878, was burnt down in 2001. It was made into a public park c.1925 and has late C19th parkland around the house and avenues leading to it, although little there from the earlier park landscape.
