Where do I put my microhome? The bulk of the cost of buying a house in the UK seems to be land price. In fact, those microhomes are _more_ expensive buildings than a traditional build - from this calculator (http://www.jewson.co.uk/working-with-you/for-self-builders/preliminary-planning/calculators/build-cost-calculator/ http://www.jewson.co.uk/working-with-you/for-self-builders/p...) the price of a 100m2 build might be ~112k, compared to the microhome 70m2 'lifetime' model. Microhomes are a nice idea, but they wouldn't help me in East of England.
