Forget the fantastic nature of its construction for a moment and simply admire the intrinsic beauty of this staircase as an object in and of itself.

Next, though, feel free to marvel at how it was made – twelve thousand perforations were created using a CNC water jet machine, a device that concentrates high-speed liquid mixed with an abrasive substance to slice through metal or granite. This approach is particularly useful when dealing with a material that might melt or deform using normal laser-cutting techniques.

From Knstrct (images by Quintin Lake Photography): “Architects Sergey Mishin and Katya Larina of Studio Mishin teamed up with Daniel Llofriu Pou and Alberto Arguimbau of Arup to build a beautifully illuminated, perforated copper staircase for Michin’s new Villa Mallorca.”

Spanning over three floors, the project required more than 2,000 square feet of composite panel, constructed from a combination of structural timber and treated copper. The resulting staircase is a both certerpiece within the finished interior, providing playful contrast against walls of gray stone and concrete, and a point of connection, filtering light to create amazing patterns on these same surfaces on various levels.
