The £250m Defence College of Logistics, Policing and Administration (DCPLA) at Worthy Down in Hampshire has received planning approval through delegated powers from Winchester City Council.
This is the second and final application for the 1,000,000 sq ft scheme, known as Project Wellesley, and will see a new college built as well as the redevelopment of its Princess Royal Barracks, in Deepcut, Surrey.
Nick Nichols, from the Defence Infrastructure Organisation (DIO), said: "We are pleased to be working with HLM and Skanska to deliver this new facility which will enable MOD to train personnel more effectively and efficiently so that they can provide the best possible support for military operations."
The college will combine the training facilities at the Defence Maritime Logistics School, currently at HMS Raleigh in Cornwall, and the RAF Supply and Movements Training Wing, based at RAF Halton near Aylesbury, relocating them to Worthy Down.
It will include new facilities such as a training college; junior ranks mess; combined officers' mess, and regimental headquarters of Royal Logistics Corps and Adjutant Generals' Corps with a new site entrance building to a museum for the Royal Logistic Corps.
Skanska will deliver the facilities in phases, enabling the site to remain live and in operation during construction, and HLM has designed the site to ensure it is capable of future expansion while in use.
The DIO, the MOD's property and services provider, originally awarded the contract to Skanska and HLM in 2014. As part of the wider scheme, the Deepcut site will be redeveloped to provide 1,200 homes, a school and other community facilities.
