Sorry for being so brief,had to step out. Building here, is very different than any where else you have been accustomed to building.You don't want to fail, it is about a $100 dollars a square ft. Now the price per ft differs by location and your taste.If you are a contractor it would be best to be on site to make sure all goes as planned. I am a licensed contractor from the states,take my advice I've done it. E-mail me and we can talk if ya like.
