Nice idea, I like the initial design. I have similar plans for the future, but some extravagant ideas are stopping me for now, as I need to secure the land first. The do the design, with an architect, see how I can make my dreams reality, start with the fence and then the building. I have some idea for the roof, that may be problematic in UK (I want the Tesla solar roof, and is available mostly in US) and surprisingly, is £2000 less than a normal roof). The rest is not so difficult, once I have enough land. And the money. :)
