I don't know why the data for the google doc is not right.
0x57e84 is house exterior size, max size is 07
0x57e85 is house exterior shape, for modern house, you need to use 03.
Let's say I make a Player 2 in my town and go through the starting point where they get a tent and save and quit. If I go into HxD and change the size value to 07 and nothing else, when I inject will the tent turn into the largest style default house right off the bat? When I tried it before it didn't work but now I'm starting to think it's because I was using the incorrect byte of 08 to change the shape too. Hmmm...this deserves further testing.
