Super Stair

From this angle those two large light fixtures look like disembodied cartoon eyeballs. The house is always watching you.

But really the point of this picture is to say look at those stairs.  The thinking behind the design was to keep them open and airy so the house wouldn't get bogged down with a big heavy staircase that sits right in the middle of everything.  

The spindles and handrails were kept thin and the treads kept open so the whole thing could float against the wall and not take up too much visual space.  

There's a nice amount of depth on each tread so the stairs can be tackled at a comfortable gait; no need to carefully shuffle up and down terrified you'll topple over and break your neck. Two skylights over the stairs let light pour in during the day and when the sun goes down, thanks to the 4 light fixtures required by Chicago's building code, it's still very well lit. All in all a perfectly beautiful design and execution.
