Notes:

Watchdog, a real estate management company with offices on the East and West Coasts, wanted to remodel the entrance interior at its Philadelphia headquarters. Before the redesign, the building had a traditional staircase that led up to a room with another stairway, this one a metal spiral staircase. The architect decided to open up this space and build a single floating staircase.

The company wanted its office to maintain its unpolished, natural style. To create a cohesive look, we took inspiration from the distressed timber columns around the workspace. We designed a mono-stringer staircase with open risers and an Ithaca Style cable railing system. The stair treads are made of reclaimed padauk wood that once served as support beams in a factory. The steel used for the cable railing and stair stringer has a clear matte coating. This matte finish protects the metal while preserving the natural, straight-from-the-mill appearance of the steel. The bare steel handrail, which has visible shifts in the color, ends in a gentle curve toward the ground.
