You Wouldn’t Download A House

Shelter is one of the most basic of human needs, so it shouldn’t be a surprise that we continually come up with new ways to build homes. Most building systems are open source to an extent, and the WikiHouse project tries to update the process for the internet age. 

WikiHouse is a modular building system similar to structural insulated panels (SIPs) but designed to be made on a CNC and insulated in the shop before heading to the site. Using this system, you can get the advantages of a manufactured home, but in a more distributed manner. Plywood or oriented strand board (OSB) can be used to make up the chassis of the blocks which can then be assembled very quickly on site versus traditional wooden construction.

One of the more interesting aspects of WikiHouse is that it takes design for disassembly seriously. How many houses have parts that are still good when they’re demolished to make way for something new? In most places, the good is hauled to the dump along with the bad because it isn’t economical to separate the two. Building with end of life in mind makes it so much easier to recover those materials and not waste them. There are certainly examples of careful material recovery, but they’re few and far between.

If you’re looking for some other ways to quickly build a house from wood, checkout the PlyPad or Brikawood.

The PlyPad: CNC Machine Yourself A Tiny House

January 6, 2018 by 58 Comments

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.
