Kabel was approached by architecture studio Abbink X de Haas to collaborate on a building exterior that would relate to the history of the area, which is within the city's red light district but is also associated with the textile industry. "This was the area where wool and cloth were dyed in the sixteenth and seventeenth century, in fact one of Rembrandt's paintings depicts the people that worked here," the designer told Dezeen.

After considering a series of laser-cut screens, Kabel instead decided to use sheets of aluminium with perforated sections.

"With these industrially produced aluminium plates you can punch out a shape, then afterwards you can still bend the perforations, so then it can either catch light or cast a shadow," he said. "If they are bent upwards they reflect the light and bending downwards they become darker pixels."

Using this technique, the designer was able to replicate a pixellated image of a curtain by twisting over a million of the perforated hexagons using a custom-made tool.

"On the back of the panel there was either a mark or not a mark," revealed Kabel. "If there was a mark you had to bend it upwards and if not then you bent it downwards, so actually everything was completely predetermined."

Each aluminium sheet is also powder-coated to keep the facade white. "It had to be white because in Amsterdam all of the houses from the canals were always painted white to get as much light as possible into the inner courts," said Kabel.

The textured panels cover the entire wall and even form shutters over the windows and doors.

"We made a maquette a long time ago where we punched paper from two sides with needles. If you look now at the building it looks exactly the same as this punched paper. It really has an almost textile feeling to it," he said.

The post Bent by Chris Kabel

Dutch designer Chris Kabel has created a circular bench made from one 10 metre-long wooden beam.

Kabel cut the long beam into trapezium-shaped pieces then fitted them back together to form a ring that retains the grain of the wood.

These pieces are held in place by a metal strap.

The bench is in use for an installation called Shared Space III in the communal space of the Witte de With Center for Contemporary Art and Tent in Rotterdam.

Here's some more information from the designer:

What do you like most about the project?

That the bench really works. If you sit with three people or more in it, it automatically becomes a very intimate space where the outside world dissapears. You really feel embraced by the tree.

What was the original concept and how does it differ from the finished project?

For the Shared Space III I wanted to make a circular bench. I liked this shape because it creates two very different spaces. Facing outward of the circle you can be alone and anonymous. You can read a book or look at the passers by. But as soon as you step into the circle you become part of the atmosphere created by the people that are already in there. It’s a bit like sharing a bath in the sauna but then without the nakedness and the wetness… It also reminds me of my early school years where on mondays we would all sit with our little wooden chairs in a circle and talk about the things we did in the weekend.

And then I thought of how I would make it. Obviously, wood first came to mind but I wanted to do something unexpected with the wood. Normally to make a circular bench out of something straight, you cut it in shape and glue or screw it back together. This however destroys the continuity of the wood grain, which for me is the most characteristic feature of wood. So that gave me the idea of cutting the wood in small trapezium shaped pie pieces that, when put back togheter, would create a circle of three meters in diameter. The bench consists of a hundred of those pieces, held together by a metal strap (just like a wooden bathtub or a wooden barrel). It actually works in the same way as the stones in an arch in a wall. Another good thing is that you can disasemble the bench, load it on a pallet and tranport it very easily.

Did you have any difficulties during the design process or assembly?

Yes, it was very hard to find a piece of wood of this dimensions. To be true to the idea I really needed a wood beam of ten meters long. Also it needed to be dry enough to cut without cracking open or breaking too much. Because when wood is freshly cut it is very wet and when it starts to dry out, the outside dries out quicker than the inside and shrinks and thus cracks because the inside didn’t shrink yet. Luckily I found this kind of wood and also a fantastic woodworker who works a bit like a mad scientist, he invents his own machines and techniques. He is a specialist in impossible projects. He has also worked for the Chinese artist Ai Wei Wei, Ettore Sottsas and Ron Arad, which made me feel confident he knew what level of finish I desired.

Do you have any anecdotes/ funny stories that occurred during the design process?

First I wanted to make the bench in my own workshop out of a thinner but also 10m long wood plank attached to a metal frame, and with the wood pieces cut by waterjet and glued together completely in one piece. We almost started doing this when I realised myself the immense size this bench would have and how we would transport it. So I measured the doors of the building and found out that after being finished, the bench would never leave the building because the doors were too small. After this desillusion the answer to make the entire bench out of pieces cut one much wider and higher wood beam and later strapped together by a metal strap, proved much more natural and logical… So in the end I thank the architect of our building (which used to be a hat factory by the way, items that easily fit through any door) for not making the doors too big…

What would you like people to take away after seeing this project?

I hope that they will have shared something with a complete stranger in this wooden circle.

About the project itself:

What materials and techniques did you use?

Oregon pine beam of 10m/ 40cm /30cm, a little geometry, and a lot of cutting… the wood is finished with a matte transparent varnish

Where were the materials found?

The wood originally comes from Canada, where it has been lying in the river for a year to wash out the wood acids. Then it has been drying to the air for two years in the Netherlands.

How long will the space be occupied by your design?

A year or maybe longer

What do you expect the bench to look like after 6 months- a year?

The wood will become even better with age so I hope it will last a hundred times longer than that…

Seam Chair and Bench by Chris Kabel	New work by Chris Kabel	More furniture stories on Dezeen

The post Shared Space III by Chris Kabel appeared first on Dezeen.

Dutch Design Week: Dutch designer Chris Kabel has won the €15,000 Doen Materiaalprijs 2009 for a chair and bench made entirely of polypropylene fabric.

Kabel's Seam Chair and Bench was announced as the winner of the annual award for innovative use of materials in Eindhoven on Saturday, during Dutch Design Week.

See more work by Chris Kabel in our earlier story.

Here's the jury report followed by a statement by Kabel:

Jury Rapport DOEN | Materiaalprijs 2009

Date: 17 oktober 2009

Location: Klokgebouw, Eindhoven

Members of the Jury: Ursula Tischner (founder of  Econcept and tutor  sustainable product development at the Design Academy in Eindhoven), Ruud Koonstra (sustainable entrepeneur / founder and director of Tendris) and Arnout Visser (designer, form-finder)

A very promising technique

The Dutch Material Prize of €15.000 goes to Chris Kabel with the Seam Chair/ Seam Bench. The project of Chris Kabel is original, ingenious and very promising. For his product he uses one single material (polypropylene) that is cheap, non toxic and completely high-grade recyclable. With completely innovating technique he shapes this material into lightweight and rigid furniture pieces.

For a sustainable innovation in the future it is important that objects are made of a single material. It saves time in recycling and the material does not become conterminated. The technique as is used by Kabel saves energy and creates a lightweight material that can replace the toxic and single use thermosetting glass- and carbon fiber resin systems.

Resourceful and passionate designers that manage to combine existing knowledge and personal insights using unorthdox methods are of crucial importance for innovation.

The jury is impressed by the potential of the novel technique. A low tech approach leads to high tech possibilities. The jury feels this technique is applicable to many more objects. With this prize the jury hopes to stimulate Chris Kabel to develop the technique further and investigate new applications.

Statement by Chris Kabel:

In 2007 I started a research project together with the material lab of the Aerospace Department of the Technical university in Delft and composites producer Lankhorst Indutech.

I wanted to see if the material Pure, that is produced by Lankhorst, could also find applications outside of the ballistic and automotive industries where it was mainly used until then. Pure is a 100% polypropylene (PP) woven fabric (comparable with the yellow and blue IKEA bags) with special properties

Pure starts as a textile cloth that becomes very rigid under the right pressure and temperature. It is woven of 100% PP yarn that has an inner core that melts at 180°C and an outer core that melts at around 130°C. At the right temperature the outer core melts and impregnates and fixates the inner cores; this process is comparable with resin and glass or carbon fibres. Having similar strenght Pure is 100% recyclabe as aposed to the glass fibre reinforced plastics that are currently used in the (furniture) industry.  This makes Pure a 100% recyclable and it doesn't nered to be downgraded, it can be used over and over again –just like gold-.

Because the Pure material is a fabric when not hardened it is also sewable. this brings another advantage: when a bag in the shape of a chair is sewn and filled like a sandbag so that it gets its shape you do not even need a mould to produce it. It is then put in a reusable bag and put in the oven on high pressure. after around an hour baking on 130°C (this is less than an apple pie) the fibers are impregnated and fixed together. A hole lets the sand come out and you are left with an ultra light piece of furniture. The blue seam is also PP by the way.

The goal of this chair protoype apart from seating is that it is a harbinger. With this chair I want to show that you do not need resin and glass or carbon fibres to create superlight (using little material) and superstrong constructions that are 100% recyclable.
