This survey is to gather dimensions etc. of livable-size cob structures.
The biggest hurdle to normalizing earth architecture appears to be building codes. Cob is the most accessible building method worldwide, yet the hardest to codify so the attempts have not yet reached strawbale or rammed earth level. Our challenge is to prove the safety of cob buildings in a language that code officials can understand -- namely, numbers. My goal is to offer these numbers in a way that also leaves the creative spirit of cob building intact.
This survey will be used to convey basic information about what is happening with cob today. I need your help and data to move forward the notion that cob construction can be just as safe and viable as conventional construction. We need to convert the graceful nature of cob buildings into a language that code makers can comprehend. It’s a difficult task that requires many solid examples. Please share the benefits that cob has given you, to benefit everyone around the world.
Please take a few minutes with your tape measure and guesstimates to fill the survey below. Photos and rough sketches of the floor plan are extremely helpful and VERY desired. Please send them to EmilyKathrynReynolds@gmail.com . Below there is an example of a cob structure in Japan, and sketches, dimensions, etc.
Thank you very kindly.
Here is an example of a 100+ year old cob structure in Japan. It is a store house, built so long ago no one knows how it was done. Dimensions shared here are in centimeters. Feel free to share yours in whatever measurement you choose.These are dimensions for the large wall seen here, with two window openings.
Location: Toyoura-cho, Yamaguchi prefecture, JapanYear built: unknown, perhaps 100~120 years agoLoad bearing: YesTwo stories15.75 square meters inner areaRoof type: Tiles on a bed of earth (probably, this is standard practice in Japan)Length: 580cm Height: 386.5cm Width at base: 40cm Width at top: 40cm Overhang length: unmeasured, looks about 20cm (so tiny!)Distance from wall to next interior support = n/a (no interior support, only exterior walls)Two window openings. One is 77cm(l) x 30cm(h). One is 80cm(l) x 76.5cm(h)
