The company said it had “drawn up a blueprint” for the largest expansion in its 20 year history.
The investment could double the size of its research and development centre in Malmesbury, creating new science and engineering jobs.
A decision on whether to progress will come later in the year.
Sir James Dyson, the firm’s founder, said: “I arrived in Wiltshire with four engineering graduates, now 1,000 more have joined us.
“But to develop the advanced technology we need, 3,000 more highly skilled engineers and scientists are required.
“We hope to create the space for them here in Malmesbury, but with a shortfall of 61,264 engineers every year in the UK, finding them is difficult.”
A new technology campus would include research and development laboratories split over four buildings.
The plans, which rely on planning approval, will be on display on 3 February at Malmesbury town hall.
