Back yard options?

by Terri
(Central Ohio)

This area is approx. 50 ft wide by 40 ft long and totally blank except for the back fence line. We want to leave the existing trees because they block the evening sun from blinding us when we are sitting on our back porch. I'd like to create an area that gives the feel of being somewhere other than on a small city lot. We are planning to put a small pond in the right corner and some sort of seating area or rustic type gazebo in the left corner. Any suggestions? We are in zone 5.
