The as-built layout is a lot different than the above plan but some basics remain. The bathroom inside worked out just great. It is compact yet very functional. Contemplating putting in a composting toilet later (?) but can imagine the drama trying to push that one through the ministry of health.. Dream on.
Electrics and plumbing follows code. Septic tank is existing as is power and well water. We will add separate hot water circuits to make use of rocket fired hot water as well as the installation of an instant heater. That thing is 2 phase at 40 amps per phase. ugly. Wait for the final as-fitted plans for further comments.
