The cotton was a nine-ounce XX blue denim from the Amoskeag Mill in Manchester, New Hampshire. Dan Howarth: Have cotton’s historic uses influenced the way you appropriated it? This is a concept that would lend itself well for layered cotton scrims that are elastic and produce a moiré effect when moving over each other. Frank Barkow: Well the installation was really a success in Marrakech and publicly and somehow strong and legible as a concept to both visitors as well as to the local population who equally appropriated the site as a place for encounter or simply to hang out. «Cotton as a tensile material sets up a number of frame and skin projects for us that could operate at an architectural scale,» said Barkow, whose studio also created a shape-shifting wall at this year’s Venice Architecture Biennale. We acquired the material locally – Egyptian cotton one of the oldest trades in this material – and brought it to the site in carts drawn by donkeys! Its also very light.»
One of the key influences for the studio’s Marrakech sun shelter was Danish designer Hans J Wegner’s 1950 Flag Halyard chair, an early example of spanning threads to form surfaces. The Two Horse Brand – two horses shown on the patch of the jeans trying to pull them apart – was a testimony to the material’s and fasteners strength. Frank Barkow: Again I would refer to Hans Wegner’s Flag Halyard chair 1950 which set the stage for cotton as a spanning material to create structural surfaces. «Its a natural organic material that is beautiful to the eye and touch,» Barkow said. Dan Howarth: Do you plan to continue to use cotton in future projects? Frank Barkow: Very light, as yarn, and strong and elastic enough to stretch over the pine frames we built. This is one of the most beautiful and weathering, fading materials in the world I can think of. The local boys who made up our building team were well versed with the material and could tell us how fast we could stretch the yarn and with what spacing in order to complete the installation in 2 weeks. Other uses of cotton are demonstrated in a series of films called Common Threads brought to you by Cotton Incorporated, each showing how the material provides a common thread throughout two unique lives. It was here that we discovered cotton yarn stretched over a steel tube frame – Wegner was a sailor – which formed the support surfaces for the chair. Dan Howarth: Have you worked on any other similar projects recently? What are your plans? Cotton is a soft cellulose-based fibre that forms around the seeds of cotton plants, which grow in tropical and subtropical regions around the world. Our task was then to test the limits of how you could scale up this idea to an architectural one. By combining riveted joints with a metal button fly joint an incredibly robust piece of work clothing was produced. Dezeen promotion: cotton was the material of choice for design studio Barkow Leibinger when forming an undulating canopy in the centre of Marrakech (+ interview + slideshow). Frank Barkow: The Kinetic Wall installation we did for Rem [Koolhaas] for the Venice Biennale this year uses a synthetic fabric as a stretchable skin activated by the motors and telescoping tubes. Studio founder Frank Barkow told Dezeen that cotton was chosen for the Loom-Hyperbolic installation because it was «strong and elastic enough to stretch over the pine frames».

Dan Howarth: How have you used cotton in your work? If Le Corbusier admired America for its industrial architecture of the last century – silos and grain elevators – in Vers une Architecture, cotton denim is the clothing equivalent to this concept. «It was here that we discovered cotton yarn stretched over a steel tube frame – Wegner was a sailor – which formed the support surfaces for the chair,» said Barkow. Frank Barkow: Its a natural organic material that is beautiful to the eye and touch. Its also very light. Dan Howarth: What is the material like to work with? Dan Howarth: Are there any other examples of cotton used in design that you particularly admire? Frank Barkow: Historically we used it conventionally, that is, as a fabric for furniture, built-ins, or for refinishing old chairs, such as Hans Wegner’s incredibly beautiful Flag Halyard chair from 1950. If you imagine the Wegner chair at the scale of, say, a pavilion then I would say that is the next project. For hundreds of years, the fibres have been spun into a yarn or thread and then woven into textiles on machines known as looms.
