Sorry I should elaborate: This is a combination of my first four ideas, them being:

1. Four seperate egg shaped pods.
2. Converted shipping container.
3. Timber box.
4. Tent and accessories.

I have drawn from my first concept and seperated the minima space into two zones; an active study cooking zone, and a passive sleep and cleansing zone. I like this because it gives me two smaller units which are easy to handle and site, yet minimises the time spent exposed to the elements etc. while in transition between the activities.
I like the idea of converting a shipping container as it re-uses an existing shell thus saving resources and greatly reduces construction time and costs. Although I have somewhat abandoned the idea because of the difficulty in siting the container due to it's large size and weight, I will attempt to use recycled materials in the construction of the finished concept.
The timber box concept is similar to the converted shipping container. I really like this idea because the material feels as though it has an appropriate life span, is easy to work with and suits the size of the project. The smaller size of the combined concept means that member sizes need not be as big. And if thought out well there is the potential to pack up the living pods (pull apart) so they can be transported more easily if need be and stored in pieces. The aim will be to transport the dissasembled units on a small dimestic trailer.
Drawing from the tent concept the fitout will be minimal only providing the most fundimental comforts. Structural concepts will also be adopted from this idea.
