The very thought of a balcony makes me think of a place jutting out from a building several floors up. But in Japan, architect Yukiharu Suzuki has designed the Sukiya House, a very modern looking home with a unique underground tunnel that also serves as a balcony.

What We Do Is Secret has a bunch of more photos of this beautiful place. If I ever get to live on a mountainside, I’d want to incorporate this into my home design.
