A few years back i helped convert a friends spare bedroom into a snakes enclosure.. although it didnt have any big boids in it only a group of 1.4.0 Green Tree Pythons & a forest worth of plants & trees. Truth be told i thought it was amazing once it was finished but the effect it had on the walls from the humidity ect ment it had to be taken down after the first 6months of it being up.. so if you do go through with it make sure you water seal everything! best of luck
