Site locat ion of Dream space
Burning Man
Central Camp

The form of the building it lends itself to the centre of the Axis of the Playa. The central spot will be for the Burning Man itself but an area in this axis would be an ideal spot for the Dream tent.
INTRODUCING PROPOSAL
_1 Site Plan of the Playa. Indicaticates main axis and the area where the Dream space would be best located onsite._2 Plan of the Double Arched Dream space_3 Section through proposal showing use and system.
_1 _2_3
To show the sort of spaces and the to test the physicality of the the proposed double arched system , a 1:20 physical model of the centre section of the proposal was created. The photographs show the spaces created in and around the proposal.

1:5 DETAIL MODELThese images of a 1:5 Model illustrate the details of the construction.
The columns have fixing plate larger than the columns diameter, to spread out tension in these ‘stress points’. For the pinch point, a circular ring plate has been designed, to let sunlight through. The diameter of the ring would have to be wide enough to withstand the tension, as it would be also weaken by the bolt holes.
HOW IS IT CONSTRUCTED?
OFFSITE: PATTERN CUTTINGONSITE: CONSTRUCTION
Offsite:Constructing the tensile membrane structure requires the fabric to be cut in a pattern offsite before it is brought to site and stretched into place.
Onsite:The system works in an equilibrium of tension and compression, however neither element works alone. In construction the primary structure must be constructed first and temporarily supported.
In order to avoid stress concentrations at the high and low points, the system has been designed so there is fixing plates or a pinch ring, with large enough radius to support this tensioning and reinforce the fabric in this area.
