I just started my house this week. I have a 40” square table to build on... though my house will be almost 42” when finished. I was going to build it in my bedroom and then realized that once it was built I would not be able to get it out of my bedroom! So I’m building it in my living room. Havanaholly warned me not to use hot glue. Thankful because I was. Instructions aren’t the best. (I’m building the Garfield kit) Definitely label everything before you punch the pieces out. I’m also taking the advice of others and will be painting before building (like staircase) and putting in flooring & wallpaper, etc. will be very hard once built. Best of luck. :-)
