After the first meetings with Constantine from AAA we could not come to an conclusion , what is should be.We are generaly concerned about to make the most suitable solution that really fits for the place and its persons. Or too stress Deleuze & Guattari to produce a black hole / white wall effect in the vitrine. So in the first meeting we could not find a suitable solution that convinced Constantin to be adequate for there office. Time passed on and I was chewing on the topic , over and over again. We had the need to use this 30 cm width for a vertical farm. So the best way I thought should be to reenforce the allready existing structure. Recycle it. Till now the plates of PC are used to hold smaler things, books and papers that are presented to the passengers that pass by the office. To carry the amount of earth that allows to grow plants , they are way too weak. To improve the structure I decided to use measuring sticks and ressemble an traditional construction technic, the trussed beam. The beauty of that proposal is that it is not a citization of an old technic . The readymade solution converts the technic in something new, that stands for something different and in that case for the work of AAA.
