While in Otamatea Eco-Village, I stayed in the Castle on the Farside. It was born by the union of creativity and hard work. I was amazed by all of the skill and time spent over the smallest of details.
All of the joinery (trimming) was handmade, mosaic patterns decorated the floor, pillars, and rooftop, and the stairs were fitted to hold each individual branch railing. They avoided right-angles wherever possible to mimic the freeform curves found in nature.
The best way to achieve this level of customization is to have the right tools and space for the job.
The house was made of bricks composed of 50% sawdust. This makes them light but sturdy, and great heatsinks for absorbing day and nighttime temperatures and slowly disseminating it to cool the house in the day and heat it by night. They chose dark tiles to be on the North Facing (remember, this is the Southern Hemisphere!) floor so that they too would absorb heat in the day and let it out by night.
The roof collected rainwater, then sent it through a filter for household use.
Ponies manicured the front lawn and kept the wilderness at bay.
All of these practical features did nothing to impede imagination in designing the home. They made a list of things they wanted and found ways to incorporate a big kitchen, movie room, tower, bridge, cellar, and abundant light. What they came out with was a fantasy made real.
