I think everyone probably has something they want for their home that is really unrealistic and impractical. Like maybe a white sofa, when you have a dog and kids.
For me the one impractical item I've always wanted is a sprial staircase. It's so ridiculous, would look terrible in the home I have now, and is just a very silly thing to want.
But I've always wanted one since I was a little girl! I also thought Geo Storms were cool, but that's neither here nor there. So instead I'll just post these pictures from Apartment Therapy.
