Property developer Ken Ross has acquired Hallhill Developments, which has been working in Dunbar for more than two decades.
The mixed-use site beside the A1 extends to more than 400 acres and includes residential, commercial, retail, recreation and education buildings.
The development is based around the five-metre-high sculpture of a brown bear - The DunBear - designed by Scottish sculptor Andy Scott, who is also famous for designing The Kelpies.
