Thanks John, I didn't consider that. Starting with this as a train shed, and sheds can have doors opening outward, but then it clearly evolved to a more residential type structure with a bathroom, carpet, AC, heat...
With the front door opening inward, I have clearance issues with anyone trying to view the layout - not a good experience for them. I have a couple ideas to consider and work out. Thanks again for mentioning this, I bet a contractor would see it and then I would have a delay later in the process, rather than early (now).
I did some looking around and I see that some localities now allow outward opening doors on residential buildings, so you'll have to check the local building codes. It also might depend on the exact usage, though with a bathroom, etc., I'm guessing it'll be classed as a residential building.
It was kinda' interesting reading about the doors, one of the reasons for inward opening doors was security as the hinges are on the outside in the case of outward opening doors and are a weak point. However, new design hinges have largely eliminated that it seems. Another reason was the ability of emergency services to "break in" in an emergency, outward opening doors resist being pushed in a lot better than inward opening doors, makes it harder for them to get in.
