You did great! I would be thrilled if I could get it to look that good.
So I will try again, but so far I can't get HD Arch 2025 to behave like that. Can you give me any more hints than what you show in the floorplan image? For example I tried the "floor 2 extended" room with ceiling height "0" and it didn't work like yours. Also, how does the extra wall across the bumpout work? Doesn't it block the interior space? And not sure I see why it would change the roof like you showed, but I can give it a try.
Thanks again.
