Glass Staircase

The Challenge: To design a glass staircase within the curved stairwell of a house with minimum visible structure to create a spacious and airy ambiance.

 
Glass Stairs

Our Solution: Toughened/laminated glass risers were designed as cantilevered supports for glass treads . The structural risers penetrate the stair drum and are bolted between steel columns situated behind the stair wall. The effect is the glass appears to come out of the wall.
Tapered glass treads were then aligned and connected to the structural risers with specially designed stainless bolts with a chemical mortar seal.
A glass landing was also incorporated within the design. The stair treads and landing were given a special non slip surface treatment to a particular design. Provision was made within the design of the riser to accommodate a bolted stainless steel handrail,which would be fitted at a later date.
