Principle 8: Integrate rather than segregate
The bathroom design works in conjunction with a greenhouse. The greenhouse, kitchen and bathroom are linked together, allowing for heat exchange.
There was some deliberation about whether or not the bathroom should remain open to the greenhouse. It was felt that the greenhouse would make the bathroom uncomfortable during the summer if it couldn't be separated, but it would be good to open it up during the colder months. A louvre window in the kitchen can be opened up when extra warmpth is required in the main living space.
A separate toilet room has been built next to the bathroom. The toilet has been plumbed for a conventional flush system (with black water bypassing the greywater system), but it's placement allows for an enhanced composting system (warmer space to assist in decomposition) or good access for a simple collection device for a composting system, like the loveable loo.
