NC-2009 IDc2:LEED Accredited Professional

MPR 2

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.

Your question is not an easy one to answer - I'd be surprised if anyone has dealt with this situation or would know for sure. Without more information, it's a little hard to imagine how a tree house would meet the MPR for minimum floor area of 1000sf (93 sq meters) but I suppose in theory it's possible.... It might also be hard to convince the reviewers that you are permanently attaching a building of that size to one or more trees without damaging them. Very unusual situations like this probably need a CIR to get a clear answer.

Thanks a lot. Yes the house would meet the minimum floor area MPR, I agree it is a very unusual situation, I guess you are right probably we would need a CIR in order to proceed. Thanks anyway
