Eastleigh Borough Council (the Authority) is delivering an ambitious housing development to meet the needs of a growing population and lead the way for the Borough and its communities. In 2018, the Authority acquired 310 acres of land in Horton Heath and committed itself to provide new homes, services, infrastructure and businesses, that project is known as One Horton Heath (OHH). OHH is a landmark mixed-use development, located adjacent to the village of Horton Heath to the east of Eastleigh, Hampshire. A dedicated project delivery team has been established to oversee the planning and delivery of each parcel of the development. OHH is intended to be not only a commercially responsible project, but also one that recognises value extends beyond financial return. An Outline Planning Application for OHH was approved on the 27/10/2025 under the application number O/20/89498. The permission comprises severable and separate phases of development consisting of up to 2,500 residential units in total (across The Lower Acre, Quobleigh Breach, The Upper Acre, Round Copse, The Holme, The Homestal, Chalcroft Farm and The Folds phases and partially within Chalcroft Outfarm Works phase), a local centre, non-residential floorspace, a primary school, public open space (including formal sports facilities and informal provisions), allotments, ecological, landscape and sustainable drainage works and key infrastructure and utilities provision including new roads, footpaths, bridleways and cycle paths. The Authority made a commitment to the delivery of critical infrastructure early in the overall process and ahead of housing wherever possible which means that much of the major infrastructure associated with housing or non-residential development will have been installed or may be under construction alongside the works to be procured.
