How CODA Used Hundreds of White Plastic Chairs To Build A Recyclable Pavilion



在这个非常有想象力和启发思考的运动中进行感性的转变,伊萨卡岛和布鲁克的CODA将几百只简陋的塑料椅子变成Cornell大学Arts Quad中的一个项目。远看是一个尖锐的单一实体,仔细的观看发现是简单、朴实的重复模块。CODA 解释说,“对象的功能不再从它们的使用(腿、扶手、作为)来衡量,而是用它们的形式(尖峰、曲线、空隙)来衡量,由于它们离开地面旋转,它们失去了与人体的关系。”我们访问了 Caroline O'Donnell,他是 CODA的领袖,他解释了完全可回收的 URCHIN在发展和建设中所面临的挑战。

This article is part of our "Material Focus" series, which asks architects to elaborate on the thought process behind their material choices required to get projects actually built.
In this exceptionally imaginative and thought-provoking exercise in perceptual shifts, Ithaca- & Brooklyn-based CODA transformed hundreds of humble plastic lawn chairs into a project in the Arts Quad at Cornell University. Viewed from afar as a spiky singular entity, close inspection reveals the simple, unpretentious repeated module. CODA explains, "the object’s features are no longer understood in terms of their use (legs, arms, seat) but in terms of their form (spikes, curves, voids) as, due to their rotation away from the ground, they lose their relationship with the human body." We asked Caroline O'Donnell, principle at CODA, to explain the challenges faced in the development and construction of the fully-recyclable URCHIN.

In terms of materials, what were your biggest sources of inspiration and influence?
We were interested in using an everyday object to play with the perception of the object. From afar, the aggregation appears as a singular (and furry) designed object. Upon approach, the viewer realizes that the unit of aggregation is a familiar object: a common chair that they have sat in before.

Describe how material decisions factored into concept design.
It was important not to damage the chairs in order for them to be reused after the pavilion is demounted. We needed to make minimal incisions, while allowing the curve of the overall pavilion to be constantly changing. We also needed the unique connections to be as invisible as possible to focus the attention on the chairs. After many tests, we settled on threaded rods of unique lengths that were connected by bolts through small incisions (ear-piercings) in the chair.

What were the advantages that these materials offered in the construction of the project?  
There are no real advantages to using chairs in terms of construction, of course. The point is to make people think about everyday objects: where do these chairs come from? Where does the material come from? Can it be recycled? How am I doing with my own recycling practices? The thoughts go in two directions: one is towards recycling and ecological footprint, the other is re-thinking about the chair as a beautiful object..the way that the light comes through it, the curve of the back, the friendly spike in the upturned legs...

Were there any challenges you faced because of your material selection?  
Many! While the chairs are rated structurally, they are rated only for sitting in the usual position, not having the loads in the directions that we had them. This was very difficult to calculate. We modeled it digitally and made mock ups and compared the results. Since they are outdoor furniture, the chairs are not fire rated and a fire rating was required from the City in order to get building permission.

Did you consider any other possible materials for the project, and if so how would that have changed the design?
We looked at a number of different chair types, but ultimately cost and the ubiquity of this chair won out. Someone asked me after a lecture if it would not be better to build this out of a standard material like plywood. They missed the point. It would of course be easier to build with a known material, but the point of the project is that moment of realization, a snap to reality, when the object becomes apparent, and a chain of other thoughts follow. It's not necessarily easy, what we do, but it is not meant to be easy. It is meant to make you think.

我们试图从制造商那购买散装以及捐赠的椅子。最终,最好的选择是用Home Depot的折扣购买椅子。所有的椅子都有独特的连接(螺纹杆),用Grasshopper建模。在几个星期的过程中,椅子被安置在垂直的C形里,然后用两天进行现场安装在一起(36 C形柱)。

How did you research and select providers or contractors for the materials used in your project?
We attempted to buy in bulk from the manufacturers, as well as to have the chairs donated. Eventually the best option was buying chairs at a discount from Home Depot. All of the chairs have unique connections (threaded rod) which were modelled in Grasshopper, and installed by our team. Chairs were built in vertical C-shapes inside over the course of a few weeks, then carried out to the site and installed together (36 C-shaped columns) in two days.
