What’s it all about?

Here’s some recent cordwood masonry history – the last quarter century – focusing on the four Continental Cordwood Conferences so far. The first was held at Earthwood Building School in West Chazy, NY on July 9-10, 1994, thus: CoCoCo/94. There were just over 100 people in attendance for the two-day event, which included talks and demonstrations by the late “Cordwood Jack” Henstridge, Cliff Shockey, Richard Flatau, Rob Roy and many others. Tours of several cordwood homes made for a busy and informative Sunday afternoon.

Earthwood, about the year 2000, before a new sun room was added to the second story.

Five years later, August 21-22, 1999, the Pompanuck Farm Institute in Cambridge, NY, hosted the second conference: CoCoCo/99. Attendees were rewarded with cutting edge developments in cordwood masonry. Henstridge and Roy were back, and joined by such cordwood luminaries as Geoff Huggins, Kris Dick and Jim Juczak: Lomax stackwall corners, electric in cordwood, multi-sided buildings, cement retarder, and paper-enhanced mortar were just some of the topics discussed.

In 2005, Richard and Becky Flatau hosted CoCoC/05, July 30-31, 2005, at Merrill, Wisconsin. A hotbed of cordwood construction, Merrill was the perfect place for the conference, and the conference was highlighted by tours of around a dozen different homes in the area. But great papers and presentations came out of CoCoCo/05 as well,, including several case studies, and more technical papers on subjects ranging from Log End Treatment and Insulation Techniques (Sandy Clidaras) to new material about papercrete (or “paper-enhanced mortar”) from Jim Juczak and Alan Stankevitz.  The Continental Cordwood Conference Papers (2005) and Cordwood and the Code (both still available) came out of CoCoCo/05 and continue to help cordwood builders with techniques and with code issues.

First CoCoCo in Canada

Another six years went by before the fourth Continental Cordwood Conference was held on June 11-12, 2011. Organized by Dr. Kris Dick, P.E., and sponsored by the University of Manitoba Engineering Department, this was the first CoCoCo in Canada. The papers – delivered in person, on video, and sent in from afar – were up to the usual quality. Cordwood in Sweden and Norway (Olle Hagman), Double Stackwall/Balewall (Clint Cannon) and Slipforms and Cordwood (Grant Nicholson) on video were very entertaining. Again, there was a good mix of new case studies and technical papers. A Cordwood Kiosk Entrance Center (image above left) was built for the University’s Alternative Village, and featured various cordwood techniques, mortar mixes and insulation methods.  The 2011 CoCoCo Papers are still available from Earthwood and elsewhere.

CoCoCo/15. From Friday evening (July 10th) through Sunday (July 12th). the Continental Cordwood Conference returns to the place of its birth, Earthwood Building School, West Chazy, New York. The schedule: Friday night is the Introductory Ceremony and a “Meet and Greet” at Meron’s Bar, an old Plattsburgh staple.  Saturday is the Keynote Address (Richard Flatau), papers presented by their authors, and a panel discussion with Q and A. (Breakfast and lunch provided.) There will be a silent auction with various special design features you might want to put into your cordwood walls.  Saturday evening is a banquet by the Stone Circle at Earthwood, indoors if rain.  Sunday morning is demonstrations, and a tour of cordwood masonry on Murtagh Hill.  After a provided lunch, the afternoon is devoted to cordwood house tours within a 40-minute ride. Here are some of the places to see:


So, please: It’s not to late to register! CoCoCo/15 is priced to be affordable to all. With four meals provided for each registrant – and the bound copy of the Collected Papers – the registration fee of $190 for an individual ($340 per couple) is a good deal indeed. We want people to come!  (A “couple” is two people registering together. One copy of the Papers per couple.)
