a) The inside space will be the trailer itself, a house on wheels, it will be able to sleep 4 (or a small family,) in fold away beds so that in the day time, the space can be a living room with benches, sofa's and desk's.
c) The decking provides an outdoor living space for good weather, a spill-over area from the small interior living space. It also gives a space to act as a workshop, entertainment space or plant nursery. A flat-topped shade above the decking, allows for extended use of the outdoor area in the heat of the day and doubles floor space by creating a balcony with excellent views to the sunset over the mountains. This balcony could be used to sleep on as well as roof-top storage and would be a perfect position for a food-dehydrator.
e) Future developments of the experiment include an outdoor kitchen area, using a fire-pit stove, an adobe oven, a partly submerged, cool storage space for food and a shade from the sun. The creation of a 'food forest' on the border of the plot and the possibility of a solar composting toilet.
