Once we had found the right 'Tree' (no tree were harmed in the making of 'Tree' Spiral!), we then had to join the trunk to the branch to make a solid, level, well proportioned and attractive shape which could be adapted and sculpted to form the shape we needed to sit steps on. Once the pattern was made it had to be made into metal!

Casting aluminium is not an exact science as the metal can have a mind of its own. Using ancient sand casting we managed to recreate the intricate details and textures of the original, the result is just beautiful, we hope!

Sand casting is a dying but skilful art form, and by keeping it alive, we feel we are sustaining an amazingly skilled British industry.

Although the actual casting process itself is not the most carbon neutral manufacture method, the metal used is recycled aluminium. So the weird and wonderful shapes we create could very possibly be traced back to a baked bean tin, which we think is rather comforting.

The components are cast in aluminium and repeatedly dropped over a steel tube to create a perfectly functioning spiral staircase and a beautiful 'Tree' sculpture. 

Our intention was to design and make a spiral staircase using real tree parts that when repeated and rotated took on the abstract form of a tree creating beauty and utility combined. See here it coming together when combined with the steps, spindles, balusters and sweeping handrail.
