It's interesting that this is I think the 3rd article on tiny housing that has bubbled up on HN recently. At the moment in the UK the government wants people to buy houses, get on the market and so on, but in an area like London where housing is pricey and space is at a premium people are going to start needing to think up clever ways to use it at ground level, rather than building up and up.

Of course, they're nigh on useless for family units, but as a first time buyer property they'd probably be quite useful in terms of pricing (as long as they don't get sold as 'designer apartment spaces') and in sensible land usage.
