The guys have done a superb job so far and the variation and fossils in the stone look great. They should weather down really well.
As soon as they have pointed up the stone in the back corner I'll get the shed ordered up. I'll be planting a few more trees this weekend and taking a look at the GSHP manifolds to see if I can lower them into the ground or if I'll neet to get Matt the plumber out for some more drastic surgery.
