Why didn't we think of this? Smart Living dollhouses incorporate lots of things we like to see in kids toys - modern design, eco-friendly wood stains, cheerful colours. What kid wouldn't want to play with this?

But the real genius behind this doll house is that it is modular.

Smart Living houses are built and rebuilt by clicking together the levels and walls, letting the kids reconfigure their house each time they play with it. And when that house gets too small, there are new rooms to purchase and add on. If only it was that easy to add a new room or two to our real homes!

The Smart Living house is $69.95 - add ons start from $7.95.
