Challenge
A beautiful Nelson home, overlooking the stunning coast line, was being built. One of the key features was the creation of a seamless indoor / outdoor flow from the living spaces to the expansive deck area that runs the length of the house. The decking area had a waterproofing membrane, which was to be covered with Italian tiles. The New Zealand Building Code requires that an exterior deck's waterproofing membrane must be a minimum of 100mm below the level of the interior floor slab and then slope away from the building at a minimum of two degrees. So how do you create a seamless flow, with the outdoor tiles sitting at the same level as the inside floor level (and at zero degree slope ) and still meet these NZ Building Code requirements?
