Nunsthorpe (sometimes known locally as The Nunny, or by its nickname of Garden City) is a suburb and housing estate in the western part of Grimsby, North East Lincolnshire, England. It is situated between Laceby Road (A46) and Scartho Road (A1243), which respectively form its northern and eastern boundaries.
There are over 2,400 homes on the estate, mostly former council properties now owned by the Shoreline Housing Partnership. There is a small area belonging to the Havelok/Northern Counties housing associations and a small area of private sector housing. There are a number of privately owned former council houses purchased under the Right to Buy scheme.
The pre-Second World War development in the eastern part of the estate is known as Old Nunsthorpe while the post-war development is called New Nunsthorpe. To the west lies the Bradley Park Estate which contains around 430 dwellings, also mostly Shoreline properties. The combined population of Nunsthorpe and Bradley Park is approximately 8,000.
To the north, on the other side of Laceby Road, is the Grange Estate and on the eastern boundary, in Scartho Road, is Grimsby Swimming Pool, which is currently under threat of closure. The Scartho Top private housing estate lies to the south. Nunsthorpe and Bradley Park are part of the Grimsby South ward of North East Lincolnshire unitary authority. The two estates are also within the area served by the South ward neighbourhood team of Humberside Police, based at the police station on Laceby Road.
In 2010 improvements to Nunsthorpe were acknowledged by the environmental campaign group Keep Britain Tidy. A quality mark was awarded after an independent assessment of improvement work undertaken on the estate by Shoreline and partners, Humberside Police and North East Lincolnshire Council, with the assistance of residents.
