Possibly the most complex component of our design was the roof. Stemming from the concept of a canvas sail roof, this presented benefits in minimising material usage and provided a 'light' dwelling with maximum ventilation. However it also presented problems such as watercatchment, given that for 8 months of the year we would have to rely on collected water, and solar panels.
This was one such variation on the design, drawn in section the roof stems from a central ridge to stiffen the structure allowing for water catchment and substituting canvas for a corrugated iron roof
To simplify the pop-up roof structure we looked at just using two roofs, sitting them at different heights and angles, sloped down and following a central ridge line (this resolved our water catchment issues)
Water storage is a prominent feature of the self-sufficent dwelling, hence we wanted to consider it in our design, make it part of the overall structure rather then an 'add on.' To have enough storage to support the dwellings occupants for 8 months we put a bladder under the sleeping quaters, sealed behaind panels of timber slats (timber that could be sourced from site). A cylindrical water tank is placed under the communal quaters, in unifying the design the drop toilet and shower are contained in two smaller empty water tanks positioned next to it. This also allows direct feed from the tank eliminating the need for a pump.
The roof was finally resolved after the above sketches, the two larger roofs follow a central ridge made for corrugated iron allowing water to run down rhe ridges to the gutters, from here the water is run down down pipes disguised in the hollow supports. The four smaller roofs follow our inital canvas design, the sit lower and envelope the building.

great sketches, you can see how the design started and evolved..
