Good with landscaping? Need help for San Jose project.

[GeneDavis]

For a friend's sister who lives in a new house, needs a lanscape plan and renderings done in order to see her vision, and for getting some quotes.

 

My problem is the project has curved walls and I am totally stumped as to how to manage them.  The project area is relatively flat, carved out of a gently sloping hillside with the concave side of the house plan bounding one side, and a concave retaining wall on the other.  The gear includes an outdoor kitchen, container swimming pool, dog fence and exercise area, dining, firepit, all that stuff.

 

Two photos attached, plus a screencap of my feeble try with curved walls.

 

No real house design work needed, just enough modeling to be able to do some exterior rendering of the landscape work.
