The new vehicle operations team facility will be developed in Fen End on a former RAF airfield in Warwickshire.
The 200-acre site is former RAF Honiley airfield and was bought by Jaguar Land Rover in September 2014.
Used to test Land Rovers, the site is now home to the Jaguar Land Rover Heritage Driving experience and some of its IT operations.
JLR’s plans were approved by Warwick District Council’s planning committee on Wednesday night.
The new site will see some 300 engineers currently split across three locations under the same roof.
JLR said the new facility will reduce the commute between sites and will provide a better environment for its Vehicle Operations Team.
Planning manager, Sukhi Clark commented: “While small in number, the Vehicle Operations Team is a major part of our business, focused on preparing and refining vehicles for global events and product launches – helping customers around the world fall in love with our cars.
“We’re pleased to get the go-ahead to develop Fen End with their needs in mind,” she added.
JLR claims new jobs will be created as part of the construction project and that staff numbers could increase to 500 once all is in motion.
The automotive giant also announced its plans to develop a green travel route for Fen End, including a car-share scheme.
