A £60m plan to develop 35 acres at Bournemouth's Aviation Business Park has been unveiled.
MAG Developments wants to build offices, warehouses and hangars within the 200-acre site over 10 years.
Stephanie Mullenger, general manager for property, said it would generate more economic activity in the area.
The programme, which it is claimed could generate 1,000 jobs, is backed by Christchurch Borough Council and Dorset County Council.
A £1.1m "highway contribution" will also be made to Dorset County Council, to improve transport links to the site.
