Sport Park

It is a thesis project, I want a 3d model in Revit. A sports park with fruit and contemplative forests of 6 hectares in total. Divided into three spaces, the first is a playground for children, the second is a roofed area with a skate ramp, climbing wall, and a row of closed facilities that are composed of administration, dance hall, cafeteria, and bathrooms (I don't need interiors views); and the third space is intended to incorporate hammocks in trees.
I want to start modeling in mid-January.
