The £700m development project will include an 85-acre business park and hotel, plus 3,000 homes, a secondary school and several primary schools.
Two-thirds of the site, at Banchory-Devenick in south Aberdeen, will become a country park.
Estate owner Rupert Lumsden said: “The local authorities face some real challenges as they seek to deliver plans that allow for growth in the economy while protecting the natural environment.
“We believe Banchory and Leggart offers a real solution and our masterplan will seek to demonstrate how we can deliver a highly-sustainable working and living space in the heart of a country park.”
Construction of the business park is expected to create around 240 jobs, with the offices likely to accommodate around 8,000 employees.
Alan Stewart, a partner at John Thompson, said: “We are really excited about becoming involved in this project and helping deliver what we know will be a very high-quality development.
“It is not very often you get to work on a proposal that offers so much in terms of employment and sustainability and is so in tune with the existing landscape.”
