OK everyone I've had an epiphany. In all the books I've read(Edible Forest Gardens, Gaia's Garden, etc.) there is much emphasis on the permaculture zones and activities that take place in them. Zone 0 is in the house, zone 1 is right outside, etc. The potential permaculture design in Zone 0 (indoors) seems to be understated.
Well, after a cold winter up in New Hampshire I came across a term called "bioshelter" which is a greenhouse ecosystem using permaculture design. I realized it would be wonderful to live in a bioshelter surrounded by plants in the winter.
Most bioshelters are utilitarian rectangles with the plants growing in key hole beds by the southern windows. I saw picture number one and it blew my mind. I decided a dome shape would be more efficient.
Imagine living in a small dome that has tropical plants growing all year inside! The building inside would be on the north wall.
Living up north the winters are long and, let's face it, we go many months without living near plants! Inside this dome you can have semi dwarf trees, a large trellis with grapes, a pond, literally ANY plant you want to have. Because it is a living space it would not get below 55 degrees which is sub tropical!
What do you guys think? Is it practical? Have you seen this before?
