As an architect I believe that in order to generate discussion of the architectural perspectives of a new building method it seems crucial, constantly to expound on aesthetical as well as technological and structural aspects which are balanced in an integrated architectural practice.
Besides these issues, the social notion of concrete can be seen as a barrier for initiating a discussion of the implementation of a new concrete technology: if nobody likes the idea, never mind how clever the technology. Especially with the cultural image of concrete is really challenged in this part of the world.

The following is a summary of my paper I just presented at the
Structural Membranes conference in Stuttgart– the session on flexible moulds was small but fun amongst a lot of more heavy engineering papers. My part presented a sort of a social experiment done as part of my thesis work on fabric formwork for concrete.

So – since fabric formwork already has ambiguity within the term I decided to create a piece of furniture with the same ambiguity. The specific experiment is the design and production of two fabric formed chairs. The exploration includes presenting to the observer physical objects of a familiar function and scale, but containing ambiguities of the materiality, construction and affordance.
The mentioned ambiguities concern optical appearance vs. the haptic perception and information which comes when touching the object and from the act of sitting down. Using fabrics for furniture and thus getting some associations right that come with the function of a chair: Fabric, patterned surface structure and a bulging surface are all associated with the notion of an upholstered chair such as the Chesterfield.
It seemed a natural choice to use upholstery fabrics for casting a chair in fabric formed concrete. Architecture students at
University of Edinburgh have studied the aesthetic surfaces of concrete cast in a number of conventional fabrics bought at the local fabrics store, including both very thin and cheap materials and more sturdy fabrics for upholstery. It was the intention of using upholstery fabric that the pattern from the fabric would transfer to the concrete surface making the appearance of the chair even more ambiguous to the observer.

An observer remarked: “I looked at the chair and in my head I knew it was concrete and couldn’t understand that it wasn’t fabric. Then when I sat on it, in my head I knew it was concrete and would be hard but I was still surprised to find that the chair wasn’t as soft as it looked.”
