Wat mij betreft valt er in Nederland überhaupt niet te leven... Having said that, i'm reminded of a story, i'm pretty sure by Larry Santoyo, of some guy in Hawaii interested in him building a
straw bale house there. He explained there's no point; it is wonderful stuff but inappropriate for the challenges of Hawaii. I mention that because i see no point in building a house in the middle of the Sahara desert; i'm talking dunes, where no rain ever falls. Whatever one builds there, it is inappropriate.
Sustainability is impossible there. For different reasons the Netherlands are comparably challenging.
For all intents and purposes sustainability is impossible in nearly the whole of the Netherlands. For U.S. readers, imagine Delaware filled with 17,000,000 people... Denmark, which is 90% the size of the Netherlands, only contains 3 million, just to give it some more perspective.
The Netherlands are a country so locked down by legislation, rules ,restrictions of all kind, and governmental scrutiny that it's like doing
permaculture in New York
City. As they say: location location location; tiny houses are amazing and i personally love them, but what's the point of tiny houses, straw bale houses, or a castle when the location it's situated at is unsustainable? I guess there's one possible merit to the idea: practice for when you finally get to a reasonable location.
