You went a bit crazy with the off-topic rating in this thread. It seemed to me that most of the posts were on topic, though they were commenting on alternative building methods. This should have been the call of the OP, who has yet to reply to any comment here. He may very well have been interested in these comments. I know it is a gray area but please try to understand there is a difference between off-topic posts (joke, completely unrelated side conversations, arguing just to argue and so on) and posts that may not directly answer an OPs question but are still related and may be of some use to the OP. Try to determine if the intent of the post was to be useful to the OP.
