ICEM: Why is there curved mesh at bottom but straight at top surface of domain?

  So I generated this mesh after creating O-grid around building but I don't understand why is it creating curved mesh towards outlet on bottom surface whereas mesh elements are straight at top surface of domain! And also, can I directly give edge sizing without creating O-grid around the building? I mean I'd apply first cell height near the building and give a growth rate in all 4 directions from the building, or is O-grid necessary?

  This is my O-grid that I've created around bluish building block in middle
