In December 1821 the Tottenham Vestry gave permission to Mr Overend to enclose wasteland, which subsequently became the grounds of the house which together with a farm, amounted to 31 acres. The house remained in the possession of the Overend family until the 1860's.

The Wood Green Local Board purchased Earlham Grove House (built c.1865), as it was then known, with 11 acres of land in 1893. The extension to the east of the building was added in 1913 and served as the local magistrate's court. The house was used as Wood Green Town Hall until 1958.

The park was laid out around the turn of the century and by 1914 boasted a bandstand, bowling green, more trees (particularly on the boundaries) and the former Chitts Hill House Lodge (built c.1822 and now known as the Mushroom House).  A second lodge house stood at what is now the High Road end of Lyndhurst Road, but has long since disappeared. The Mushroom House is a Grade II listed building. It is circular under a fishscale slate roof; originally, it would probably have been thatched. The red brick and pebble-dashed pavillion with a red tile roof was erected on the north side of the bowling green before 1935.

The bandstand disappeared sometime between 1957 and 1973 and in the same period the north west corner, adjacent to the Mushroom House was re-landscaped as a sensory garden for the blind with raised beds and some fine examples of limestone.

Woodside House gate is the original approach to the house and is marked with red brick, tuck-pointed piers with sandstone copings surmounted by bronze lamp bases.

The boundary trees are mainly some very fine oak trees on the east side, horse chestnuts and limes.

In 1984-85 a large part of the Park was excavated to build a tank for the Muswell stream flood relief scheme.
