Here's a summertime picture of the property (South is down). ~5 acres on the south side of the road, ~3.5 acres on the north side. As you can see, if I want the new garden on the south side, I have a lot of clearing to do. The field south of and near the road to the west (left) is ~250 ft x ~75 ft, but with the trees there only about 50 ft of that width is usable because of shade until I clear some out.
The pavilion is to the east and is about 24x48'. The well house is about 75 ft south of the pavilion (hidden by the trees).
