You know you have achieved perfection in design, not when you have nothing more to add, but when you have nothing more to take away. Antoine de Saint-Exupery
“That’s what I aim for, but still have a way to go. The core of my house (the insulated part without the greenhouse and wrap-around shed) is about 11′ x 11′ on the outside. It contains everything I need on a daily basis. There are also a few sheds, but much of what I have stored away I can do without, and most of it will be sold or given away. Possessions can be a millstone. In a small dwelling it is necessary to make use of all available space, be fairly organized, and very ruthless about possessions. A small house (or mobile structure) has many advantages too, it is very cheap to establish, more ecological than a big structure, easier and cheaper to maintain, heat and clean. In the gallery you can see a few tricks I used to get as much as I could into the small house, without making it feel too cramped. Good sources for inspiration are boats, caravans and canal boats.”
