Well, we'll keep all the surounding untouched. The concrete is just the surface to accomodate outdoor kitchen, a table & hopefully, a jacuzzi or, for the times being, the kids "pool". On top of the concret I'll run some creeper vines in the to-be wooden patio. Rest assured that all the trees and surrounding pastures won't move an inch. Before being concrete this was largelly gravel in any case. Heat behaviour has been a concern from the start but the balance tipped towards this outcome.
