During the summer of 2005, Terry Jantzi a Kitchener Ontario resident, designed and constructed this cooker in approximately 3 hours. The majority of the materials were sourced at the Habitat ReStore located in Waterloo Ontario. The oven sides, braces, mirrors, mirror base, rear cover of indoor/outdoor carpeting and window were all purchased for less than CDN$30. The foil pipe insulation and assorted hardware fasteners were the only purchased items. The carpet was stapled to the wood frame and trimmed. The foil insulation was cut and stapled into the oven cavity.
