There are a few things that bug me about buying a new home or moving to a different one:
1) When one moves all of their animals, trees, gardens is left at the house and is unretrievable once the house is sold. Our items should come with us.
2) There should be options to update the size of the backyard and cabinet(by use of currants or something similar to building a new street) if one feels the home is getting cramped.
3) Custom interior designs :D
