Here is another nice home design idea - a floating stair. The residential design world tends to do things the same way over and over while commercial building design tends to be more experimental. Below is an example of an interesting floating stair that would be well suited to any contemporary / modern house plan.
The stair is supported be a series of steel stringers which span from floor to landing. By holding the bottom of the riser above the tread one gains the illusion of "floating". The flat wood paneling at the interior wall and the commercial grade "storefront" window system beyond add to the modern aesthetic.
So when you working with your Architect on the design of your new home, ask him / her to think about the details in a unique way. It is the details that will make your home truly special.
