Inflatable Architecture - Thoughts of Flexibility

With the requirement for this project, and as a theme developed by our previous design group, our mobile architecture units which will be distrubuted around regional Australia.  These spaces will need to be flexible enough that they can adapt now and over time. 

One of the first concerns of mine for designing these mobile units is the size and weight.  Obviously, the larger and more complicated these are, the more heavy infrastructre will be required to manage them, and the more difficult they will be for users to interact with and operate.  Also, if the units can be smaller, and more flexible once they reach their destination, there will be the ability to ship more at one time to make the whole process more economical.

I struggled at first with the idea of the whole structure needing to be incredibly rigid, clad in steel, or timber etc.  While this might give them a certain strength, I thought, is it really necessary to have to fortify them this much?!?!  The following is an image I found, and have previously posted which I reviewed and gave me a new idea:

The mobile units will basically require 2 things:
1 - A solid, transportable body, allowing connection (and containing) to services which will carry equipment and personnel depending on the required function.

2 - Enough space/s to be able to perform its required function

I had the idea to utilise this shell/frame as a services/storage core and combine it with clip on sides, which would expand into various spaces.  I had a meta think......."why am I thinking about rigid 90 degree joints and rooms limitied to the sizes set out by this core?".  The same day I drove past the Moscow Circus, set up in a park several blocks from my home.  The ticket booth/entry was a caravan, surrounded by a giant inflatable castle style design.  I thought...."if they had to transport this everywhere and set it up time and time again....this is such a simple way to do it!"  As tacky as it may look, it functions brilliantly and packs down within the caravan which it currently frames.

Here are some exemplars I quickly found to see what is possible with this system:

With the added level of flexibility I require for my mobile units, the required spaces will change.

For example, if it were to be used for a mobile dentist service:

-  It would require a waiting space, a dental work space (requiring the services and specialised equipment- light, air, water etc) and the spaces for the dentist and dental assistant to stay.

For example a mobile classroom might require:

-  Teaching equipment and services (internet, AV equipment etc) as well as a space large enough for a handful of students to sit and study and a place for the teacher to stay.

For example a mobile parliamentary office might require:

-  Internet and AV services, a flexible meeting space of various sizes, a place for a politician to sleep, this may also include space for their family to sleep and travel the country with.

etc etc etc................

This system would allow a variety of clip on sized rooms, to act as the secondary spaces to the service core.  They would perhaps fold down once delivered to site, and inflate/deflate with the flick of a switch and an inbuilt air-compressor to the service core.
