The Maslow CNC project is a CNC mill for sheet woodwork that is designed to be as inexpensive as possible and to be assembled by the end user. They’ve dropped us a line to tell us about a recent project they’ve undertaken as part of a collaboration to produce the PlyPad, a tiny house for Kenton Women’s Village, a project to tackle homelessness among women in part of the City of Portland.
Their write-up is a fascinating look at the issues surrounding the design and construction of a small dwelling using CNC rather than traditional methods. As an example their original design featured an attractive sawtooth roofline with multiple clerestory windows, but sadly a satisfactory solution could not be found to the problem of keeping it waterproof and they were forced to adopt a more conventional look.
The walls of the building are a ply-foam bonded sandwich, and the house is constructed in 4 foot sections to match the width of a sheet of ply. There are several section designs with built-in furniture, for example containing a bed, or storage space.
This house was designed to be part of a community with central washing and sanitary facilities, so it does not incorporate the bathroom you might expect. However it is not impossible to imagine how sections could be designed containing these, and could be added to a full suite of construction choices. We are reminded of its similarity to the WikiHouse project.
We covered the Maslow project back in 2016, it is especially pleasing to see that it has been something of a success.
In many parts of the world, living in a trailer has gained a social stigma. We’re talking about a rectangular building placed on three wheels and towed to your preferred plot of land. It’s going to take a lot to break that social stigma, but this is a pretty sweet attempt.
PassivDom is an off-grid home. It sidesteps the electrical grid as well as water and sewer service. It’s marketed as utilizing revolutionary breakthrough in wall insulation which they claim makes it very easy to heat and cool. In addition to this self-sustaining angle, it taps into the tiny home movement with a footprint of just 36 m2 (4 m by 9 m; about
118 390 ft2 or 13′ by 30′).
For this to make sense you really need to get the “Autonomous” model, the only one that is designed for “off-grid” living and comes with solar panels and battery storage plus water storage and purification. That’ll set you back 59,900 € (about $63,461 USD) but hey, it does come with “high quality minimalistic furniture” which the best way we can think of to serve Ikea nesting instinct without saying the brand name. Yep, this ticks all the “marketing to millennials” boxes. We’re kind of surprised it’s not doing crowdfunding.
So where’s the hack? Obviously this is a hard sell at 1,664 €/m2 (
$538 $163/ft2). A project of this size and scope is well within the purview of a single, motivated hacker, and arguably a weekend project for a well-skilled team from a hackerspace. Tiny Houses started as a build-it yourself so that’s already solved. We’ve seen what it takes for hackers to add solar to their RVs, and experiments in home-built power walls. Water storage and purification is already solved and quite affordable at the home store.
Has anyone built their own off-grid tiny house? If so, let us know what went into it. If not, what are you waiting for?
