While volunteering at a cold-weather shelter near my home in Grand Forks, British Columbia, I was consulted about designing transitional housing for the homeless. After some discussions with the staff and guests at the shelter I went home to draft some floor plans that I thought might meet the housing needs of the homeless, with dignity, at a low initial cost.
I was then struck by my incredible hypocrisy. Here I was living in a typical 1200-square-foot house – how could I possibly know what would be required for someone to live in a Tiny House?
I asked myself, “What would be the very smallest space that I could live in with pride and comfort?”
It’s now one year later – in seven months of leisurely construction and frantic downsizing I have built, and moved into, my 125-square-foot tiny house on wheels. I am irrationally happy in my new home, and I now feel somewhat qualified to suggest some design considerations for small living spaces.
Pete’s 125 Sq. Ft. Tiny House on Wheels in British Columbia
As an architectural designer/contractor I have designed and built over 40 standard houses so, as I stood on the rusty deck of my newly acquired, $700.00, 8’X18′ trailer I was excited to get started on the plans for my future tiny home.

Chest freezer re-purposed as insulated, Japanese-style sit tub and shower pan.
Composting toilet with Separatt diverter insert. An initial nest of straw keeps pail clean when emptied. Peat moss used as a cover.
Tongue and groove ceiling with post and beam construction, all from locally-milled timber. Recycled cabinets, doors, windows, etc.
Clothes storage in large, roll-out drawer under bed as well as bedding, off-season clothes, and a large water tank.
Bedroom doubles as a comfortable sitting room for company.
Hanging clothes closet and kitchen storage. Chest freezer converted to energy-efficient fridge.

My 5 Tiny House Design Rules
Rule #1: No loft. My first design consideration comes from being 70 years old – navigating out of a loft to pee at 3am was not super-attractive to me. I also know from experience that our hot summers create hostile sleeping temperatures in lofts.
Rule #2: I wanted a home that didn’t require intricate magic tricks to be performed before I could engage in each new activity. I wanted to live in a less complicated environment than the transforming, fold-out, drop-down, nesting, Rubik’s Cube storage strategies of some Tiny House tradition. I embraced ‘simplicity’ as my muse.
Rule #3: Floor space must provide more benefit than simply offering access. In search of simplicity, I wanted to eliminate any floor space that served only the single function of moving traffic from one space to the next.
Rule #4: Provide maximum R-values. Post and beam construction allowed maximum insulation levels and minimum weight by severely reducing structural framing and thermal bridging. At this moment (10am on Sunday, January 3, 2016), although quite unusual, the temperature outside is -4 F and all my attention to insulation is paying off big-time.
Rule #5: Design for self-sufficiency and a low carbon footprint. Doors, windows, cabinets, etc. were recycled from my local ReStore. The capacity for on or off-grid living was accomplished by installing full solar voltaics, propane, a Honda generator backup and on-board water – as well as providing for all the standard RV hook-ups.

On-demand hot water and stovetop are fuelled by propane.
Energy-efficient freezer/fridge conversion kit is by Australian innovator Dr. Tom Chalko.
110V, 9,000 btu heat pump provides space heating and air conditioning.
A compact, insulated, Japanese-style sit tub and shower pan is a recycled chest freezer.
Bucket composting toilet has a Separett insert.
