I quite hate the idea of mobile homes. Everything is so cramped up and you can never be fully comfortable. But I must admit that 'Blob VB3' by architectural firm dmvA is pretty cool. It's designed as a mobile unit for the office of Xfactoragencies as an extension to the 'house'. It resembles a massive space-egg and includes a bathroom, kitchen, lighting, a bed and several niches for storage. The nose of this blob opens automatically and it doubles as a porch. Apparently, it's very easy to manoeuvre around. Take a look at the pictures, it certainly packs a punch.
