Low impact Eco Resort

Hello, My company is looking to partner with the development of a low impact resort on an island located in Myanmar. It will have safari style rooms which will be part wood (deck & lower wall) and part canvas (upper wall and roof). They will be on a concrete foundation with wooden pilings for support. Can such a half tent building meet this requirement? There will be a couple of permanent concrete buildings as well. Could the project just certify the concrete structures if the tent structures are not allowable? Thanks for your help. John
