House float: Architect Tim Pyne reckons his floating "m-house" is the solution to spiralling house prices and land shortages.

The m-house – which is legally classed as a caravan – costs about £145,000.

A flat of the same size in London Docklands would cost around £445,000.

Glasgow council is understood to be considering the m-houseas a way to regenerate its docklands area.
