Prefab thatch wall panels (built indoors during the off season) and materials palette which the Treehugger writer calls ‘almost edible’.
“John French, CEO of the university’s Adapt Low Carbon Group and project director, … was eager that the next generation of buildings at UEA should move away from high thermal mass and a dependence on carbon-intensive concrete, towards natural and locally sourced materials.”
“The building also features a wide array of other sustainable materials including recycled timber finishes, wood wool acoustic boards, spray-on cellulose, and wall coverings made from hemp, nettle fabric and reeds”
Unlike earlier 3D printed houses which used plastic, this one uses clay. Very cool!
The World’s Advanced Saving Project, or WASP, has just unveiled a giant 3D printer that – rather like a real wasp – can build a house out of the stuff.
The 3D printer, called BigDelta, works much like any other you may have seen – layering up a material into a pre-determined structure. The difference is that it stands 12 meters (40 feet) tall and claims to be the world’s biggest.
It was unveiled this weekend at the three-day “Reality of Dream” rally in Italy, where BigDelta was made. In a statement, WASP proposes that its technology could help meet the rising demand for housing, citing a UN calculation that over the next 15 years there will be an average daily demand for 100,000 new housing units.
It is thought the technology would be of most use in disaster or war zones, where the speed of production could help those who have become displaced. The use of natural materials could also benefit the environment by reducing cement – a major contributor to carbon dioxide emissions.
You can watch the journey of BigDelta from desktop prototype to field-dwelling giant here.

UPDATE: The Indiegogo campaign has ended, and we heard today that our new Romanian friends managed to raise €1,266 – not all that they’d hoped for, but hopefully enough to do a lot of what they’ve planned. I’ll update this post more as I hear news.
We recently got word of some people attempting to spread the word about strawbale construction and other natural building techniques in Romania. They’re doing an Indiegogo fundraiser to get the funds together to attend and exhibit at the largest construction expo in the country.
They only have until midnight on Feb 14th to raise the needed money, so let’s show them some love!
In their words:
Last year we started a project called Earth Safe Design, aimed at building straw bale houses in Romania and raising awareness about straw bale building and natural building in general.
In April 2014 we want to attend Construct Expo, the largest construction fair in Bucharest. This event gathers 17000 visitors over a period of three days and gets coverage all over the mass media.
We are sure that this event would be a big step on the way to establishing straw bale building as an acknowledged building technique, one that will be embraced by more and more Romanians in the years to come.
Unfortunately, we cannot afford the fee for taking part in this fair, nor the other expenses involved in printing and buying building materials. Below you will find a detailed list of our expenses.
We are addressing our appeal to straw bale builders, straw bale house owner, and straw bale enthusiast who know and understand the benefits and the delight of living in a natural house.
We encourage you to donate to their campaign. We have.
On October 3, 2013 the International Code Council (ICC) approved final action RB473-13 as a new Appendix R in the upcoming 2015 version of the International Residential Code (IRC).
The approval marks the latest advance of straw bale construction in the building codes and permitting process. It is the highest approval to be granted for the construction method and will be adopted by thousands of jurisdictions around the United States in and after 2015.
The process of creating the IRC appendix was spearheaded by Martin Hammer of Builders Without Borders representing the California Straw Building Association, the Colorado Straw Bale Association, the Straw Bale Construction Association –New Mexico, the Ontario Straw Bale Building Coalition, the Development Center for Appropriate Technology and the Ecological Building Network.
Thousands of hours of work have been donated by Martin and various individuals within the straw bale construction community to make this milestone a reality. We thank all of them for their hard work and look forward to even more widespread acceptance of straw bale building in the construction trades.
For details and a link to a copy of the appendix, visit TheLastStraw.org. A huge thanks to the hard-working bale heads that spent years making this happen!
Did you know that the early registration deadline for the 2012 International Straw Builders’ Conference is only a few days away! The conference itself runs from Sept 16-22, 2012.
It’s not too late for EARLY registration for the 2012 International Straw Bale Building Conference in Estes Park, Colorado. EARLY registration ends
July 16th July 31st so get hopping and sign up!
If you have never attended an International Conference you are missing a great opportunity to meet some of the professionals from around the world and to experience an event which will boost your energy and confidence in building with Straw.
And if you have never been to Estes Park, I’m told it is one of the world’s most scenic venues – adjacent to Rocky Mountain National Park, the mountains and wildlife are to die for. The YMCA conference site is excellent, and the facilities food and accomodations are super according to friends who have been there.
By the way, a conference like this is NOT just about straw. It’s about plasters, earthen floors, building for cold (or hot) climates, compressed earth blocks and more.
SO – get busy and register today!
I’ll see you there!
Founder, Sustainable Sources
For a long time, straw bale builders have wanted to legitimize their favorite construction method by getting building codes passed specifically allowing plastered straw bale construction. A lot of headway has been made, starting with the Pima County code for load-bearing straw bale construction back in the 90s, followed by a fair number of local and even some state (California) straw bale building codes.
But it takes a lot of work to get something like straw bale construction passed in each jurisdiction, and it seems that nearly each new construction project has to reinvent the wheel, educate the local code officials, etc.
To remedy this problem, a group of dedicated baleheads have been working over the past several years to get straw bale construction accepted into the Big Daddy of all codes, the International Building Code (IBC).
International Code Council will hold hearings in Dallas on either Monday, April 30 or Tuesday, May 1 regarding the Fire Resistance of straw bale construction, and a week later on structural considerations. These hearings are just part of the many important steps needed.
Sustainable Sources founder Bill Christensen will be joining longtime code advocate David Eisenberg (Development Center for Appropriate Technology), builder/architect Ben Obregon (Sustainable Design Center), and architect Gayle Borst (Stewardship Architecture and Design~Build~Live) in Dallas for the Fire Resistance section of the hearings. Bill, David, and Ben participated in the 2006 fire tests which gained plastered straw bale construction ASTM 1- and 2-hour burn ratings (earthen plastered and cement plastered, respectively). See the video.
The hearings are free and open to the public, though you are required to register. They’re also being streamed, in the event you can’t make it but are interested in the proceedings.
To see all the supporting documentation including the proposed Straw Bale Construction chapter, and testing reports regarding moisture, structural, seismic “shake table”, fire, and of course thermal tests, see EcoBuildNetwork.
David and architect Martin Hammer will return the following week for Structural hearings.
