Dyson has announced plans to begin work on a second Technology Campus.
The proposed 517 acre space in Hullavington, Wiltshire is on former Ministry of Defence land and is nearby Dyson's global headquarters in Malmesbury.
Dyson has more than tripled its UK headcount in the past five years and currently employs 3,500 people in the UK - half of which are engineers and scientists.
James Dyson said, "After 25 years of UK growth, and continuing expansion globally, we are fast outgrowing out Malmesbury Campus."
"The Hullavington Campus is an investment for our future, creating a global hub for our research and development endeavours."
Prime Minister Theresa May said, "This investment is a vote of confidence in our modern industrial strategy and our determination to cement the UK's position as a world leader in high-tech engineering."
The current headquarters is set to become home to the Dyson Institute of Engineering and Technology from September.
The restoration of the WW2 hangers at Hullavington will begin in May with employee occupation scheduled for the end of the year.
