been thinking about having a proper staircase in the workshop for about 5 years now and Bram in our design department in Paris has been putting a lot of thought into it.The three different levels will be linked seamlessly by a square spiral. Bram uses a programme called RHINO similar to CAD , and the end result can be drawn up and all dimensions worked out and a construction drawing produced. The visualisations are great and can be used to work out any problems before a cut is made in the metal. Bram has been helping us work on a number of projects and working together we come up with great solutions. We were at school together and shared the Lanford Prize for Design back in 1992
