From my initial shape generations mentioned below a number of problems were identified, the first was the problem of floor space, the second was complexity and the third was practicality. Some of the shapes that were produced using this method were unworkable as shelter but through this process of idea generation I was able to identify them and abandon them.
My main observation was that the simple shapes were the most affective, with this in mind I selected a number of shapes to take forward and develop. Through my development of the shapes I have ended up with a number of interesting concepts for my shelter as seen in this image.
