Hey Pandamonk, I haven't seen your plans, but I'm a bit curious about some things I saw in the pics. Is this a "room within a room" design? Is this being built on an existing slab?
Not to be negative, but am I missing something here? It looks as if there is NO foundation, is that correct? Dose your local building codes allow building something like this with no permits, or do the pics not show certain things. Like...ceiling rafters? You aren't really planning on hanging drywall from those "2x4's" spanning the space are you? Is there a "seperate" floor for the interior space? Sometimes work in progress pics suggest things that arn't there, and if thats the case, sorry. But if what I see is reality....man, MY local building inspection department would have a field day
No offence intended, as the pics don't show everything. Thats why I am asking questions. Say, do you have any drawings, like sections or details you could post. Some people might learn something from them.
