Not sure if this is the right section, but house construction didn't seem to cover it. so please move to appropriate place if required mods, thanks.
After numerous iterations we have nearly finalised on our layout. (See below). It made sense for us to move the master bedroom above the garage to aid the flow of the house and we really like the layout. I had however previously avoided this because I assumed we would have issues with being inside the thermal envelope and air tightness and so forth. It will be a timber frame or SIPS build and I am hoping to achieve high levels of air tightness, is there anything I should be looking at or concerned about with our master being above the garage and obviously the garage will be outside the thermal envelope and not very air tight at all. Will the floor construction need particular attention? . any other thoughts.
