David Ballinger, founder of 
MetroShed, recently emailed us about his latest project: a prefab houseboat.
From the press release (PDF):
The MetroShip represents 7 years of boat design and planning to utilize unique materials for a houseboat application.  I wanted to incorporate the manufacturing efficiencies of our pre-fab buildings (MetroShed) into a luxury aluminum hull houseboat product.
.... most houseboats have lots of windows to let light in – but the result is a very poor looking design.  We use transulent thermal aluminum walls....
Some highlights:
 - 
     48ft x 12ft
 
 
 - 
     modern New York City loft style interior
 
 
 - 
     The furniture is all ‘green’ – using recycled frames and remnant fabrics 
     made by sister company, MetroSofa.
