Constructing portable buildings

I got the idea of portable buildings. Now I just need to join all my research, experiments and this idea together. I decided to make small units that could be used on their own or joined together to create big spaces. I got this idea from shipping containers used for temporary shops.

Since I had a clear idea what I want to make I just needed to decided how. I knew that I want to use the expanding foam inside little spaces as it would create natural shapes and relate to all my research. 

I started experimenting and drawing plans how to construct units that could be joined together.

The primary idea was to get big irregular piece of expanding foam and cut it into smaller bits. I made a little experiment and realised that it is very hard to join irregular shapes.

Therefore, I decided to use geometrical shape as a container to keep the irregular foam inside. I was drawing all the different shapes looking how could I join them together. I wanted to be able to join shapes in as many different ways as possible. I found out that pyramids can be joined in quite a few ways. So I started making test models so see how can I actually join them.

I tested quite a few nets, sizes and shapes of pyramids as I needed to know which ones are the most efficient. Then I started cutting them and adapting nets to achieve the shapes with open corners or sides. The first outcomes were quite unsuccessful and uneven. I corrected my mistakes though and made changes to the nets as well. The other improved models were quite good and I decided to change materials. Once I did all the experimentations with different types of pyramids I had all the nets ready for mass production.
