Yes, you can expand your house into any shape or size that you wish.

As there are expansion packs inside of our online store that you can take it advantage of to expand your house and customize it in anyway you choose.

In fact there are entire playsets that can replicate famous area's or locations of other worlds. An there are of course theme packs for those who simply want a theme.

Any size, Any style, Any customization. It will all be possible for you choose and customize.

The only thing that will stay the same is The door leading out of your world and into the multiverse. That can be changed, customized and altered, but will always be there. That is the only constant when it comes to home customization.
