Stairs are often boring utilitarian things hidden in the dark recesses. In fact they should be celebrated as a healthy fossil fuel free way of getting vertical and should be up front and center. A lot of readers complain that so many of the stairs that we show are dangerous deathtraps. That's why this one is interesting, almost outdoing Steve Job's patented glass stair.
The connection of the tread to the supporting vertical glass panel is invisible. How do they do that?The house addition shown on the Contermporist is another story, But AR Design Studio has done such a lovely stair that to criticize the glass addition would be cruel.
