Elvetham Heath is a residential area and civil parish, containing 1,868 residences, on a 311-acre (1.26 km2) site, just outside the north western boundary of the town of Fleet in the English county of Hampshire. The population of the civil parish at the 2011 Census was 5,183.
Elvetham Heath was built on reclaimed pine plantation/heathland between the M3 motorway and the London-Southampton railway line, 2 miles (3.2 km) north of Fleet town centre. Formerly known as Railroad Heath, it previously belonged to the local Calthorpe Estate. Construction finished on the development in June 2008.
Elvetham Heath serves as a commuter area to local towns; Basingstoke some 12 miles (19 km) to the west, Reading is 16 miles (26 km) to the north and London is 37 miles (60 km) to the northeast. The development is located precisely midway between Southampton and London. It is adjacent to the M3 motorway, 12 miles (19 km) from the M4, and 14 miles (23 km) from the M25. Fleet railway station is approximately 1.2 miles (1.9 km) from the centre of the development.
The district has a Local Nature Reserve. It is managed by Hart District Council, with the intent to move it back to typical heathland, with some marsh areas. The area supports species including slowworms, lizards, and dragonflies. Rare breed cattle graze in the nature reserve during the summer and autumn.
