According to MPR 2, buildings should be constructed on already existing land. On the supplemental guide it states that cantilevered buildings over water, highways, etc, are acceptable. So it is not clear to me if a tree-house is acceptable for LEED certification. It is a permanent building, it is not technically on ground but it is cantilevered, and I think the intention of the MPR is the building not moving to other environment, which is not the case. Sorry, I didn't know where to put this question. Hope you can help me out to clarify.
Thanks.
