Build a Wood Fired Cob Pizza Oven – SOLD OUT

August 26, 2017 @ 10:00 am - 5:00 pm


20100408-cob-oven-smallo-thumb-625xauto-83121Wood fired pizza, fresh baked breads, slow cooked meats and tasty sweet treats; they can all be done with a single firing of a thermal mass cob oven over an afternoon.    Join Adam Krop, experienced cob builder, as he teaches all the steps necessary for you to build your very own cob oven (cob is a mixture of sand, clay, and straw). 

A cob oven is a thick monolithic domed structure that gets heated from the inside with a wood fire.  The thermal mass of the oven walls gathers and stores the heat and the wood fire is removed (or pushed aside).  Then the oven is ready for baking as it slowly releases the radiant heat for hours.

COB!  It is an English word and method for one of the most fundamental building materials known.  Used for millennia, lasting for centuries (with some love and care) and used the world over, it is just mud and straw, and it is sometimes made into adobe bricks or compressed in rammed earth formwork.

During this workshop, the cob will be mixed with your feet, and stacked with your hands.  It is the simplest, low cost, low embodied energy and infinitely recyclable building material around and it can be enjoyed by both young and old alike.

You will learn:

  • How to identify, test and amend your local soils to make it suitable for building
  • The “burrito” roll mixing technique and how to stack and stitch your mud into a solid mass
  • How to lay a fire brick base, insulate below it, mould options to create the oven void, and detail your oven for efficiency and long life


You will want to attend this workshop if:

  • You want to build your own wood fire oven and want guidance on how to start
  • You don’t mind rolling up your sleeves and getting a little (or a lot) dirty.
  • You are interested in natural building
  • You want an introduction to the fundamental principles of building with mud and detailing so you can take on more complex projects
  • You want a hands-on experience working and building with cob


You will get:

  • a full on, and hands on workshop experience (but everyone works to their ability and comfort level – there is something for everyone)
  • the confidence to go and build an oven on your own
  • some design plans and the opportunity to talk through your design ideas with a knowledgeable and experienced builder.

When: Saturday August 26th 9:00am – 5:00pm

Where:  Wellington Centre for Sustainable Agriculture – 570 Belsyde Ave., E. Fergus, ON.

Cost: $110 (Early Bird Special until June 1)

Adam_photoAdam Krop is a builder, designer, maker, grower and Intern Architect.  His love of soil stretches way back with his roots in human health, environmental science and landscape restoration, but somewhere along the way he landed in Portland for the VB5 and received a crash course in building structures and community with mud.  He has since worked professionally as a straw bale home and natural builder, plasterer and workshop presenter with Evolve Builders Group and recently completed his Master of Architecture degree at Dalhousie University and is working towards his professional license.  He still loves mud.  Always will.
