Wow, seriously commited to torturing students err, I mean reducing personal living space impact on the environment......
Very impressive but I would have a certain number of issues with that design as is.
1. The access to the sleeping loft, try that after one too many pepper schnaps and the world would do more than spin.
2. The toilet/shower/bathroom combo, lived in a caravan for a few weeks on a holiday site and it was NOT a very pleasant experience. Imagine the typical student morning after the night before and one's morning shower can be a real trial of determination.
Overall I applaud their imagination but think the level of compromise is higher than really needed it does give me an idea for a forum challenge though if anyone is up for it, all comers welcome, you too Dave if you have time.
