Our group had a starting point from the pre-workshop try-out model. Here the focus had been on the inflated structures relation to the body - more precisely the circulation and transfers of material that is ever on-going in side the human body. We created a simplified model, where a cube within a cube was to depict the perforating membrane that controls and allows materials to either enter or exit. The inner cube was perforated to regulate the pressure of air entering the cubes, and furthermore had a function as inflator of the big cube.

When we arrived at the Instant Aarhus Workshop, we assembled a group of 8 people, and started discussing the main points of our coming structure.

What we concluded was that a central core was to describe the one side of a membrane, and a walk able channel the other, and in between these to states the plastic would divide and function as a membrane. The channel turned out to be a bagel/doughnut shape, to enclose the environ-ment. The membrane unfolded more when we decided to make a closed opening in the plastic channel - only accessible from outside the inflated city.

It had to be almost invisible, and hard to pass, so we sliced the structure like a section, only to close this whole on both sides. We found inspiration in the Marriot Hotel in New York, where the elevator space is centred in a circled room with one core, and a machine forced you to take a certain elevator, potentially the one furthest away from you, enforcing you to move all the way around in a circle. So in this circulated plastic structure you could walk around - except from one point where you had to go all the way back.The inner core was a private space only big enough for one or two people to occupy. We made it a plaza and planted a little tree in the midst, that was only visible from inside the structure. In this way, the little private space could function as a calm break from the puzzling city life, entering nature in the centre.

We tried to calculate the proportions of the structure, and wished for it to be high enough for an adult to walk standing in it. We drew it as a doughnut in Rhinoceros, and 1D stretched the pro-portions, ending up with a higher arch. From here we could unroll the arch and draw our tem-plate, using the technique, we used making the first giant dome.
