First of all, this looks like an awesome challenge :D but I have a few questions and I apologize if they've already been asked.
So I seen the recommended lot size is 20x15, but I don't see how a "mansion" would fit on this size. Can you use a bigger lot size or eventually move lots?
Also, how long are you supposed to live with the 8x8 before you can add other rooms?
One last thing is, if you add steps leading up to your house does that have to fit in to the 8x8 limit?
Thanks,
