The outside layer of clay belonged to famous Haida artist Bill Reid

Sculptor, George Rammell, donated Haida artist Bill Reid’s clay. “The clay I provided belonged to Haida artist Bill Reid. It provided the form for many of Bill’s sculpture projects including the “Whale” at the aquarium, and the huge bronze “Spirit Canoe” at the Vancouver airport. I also used it for my bear track project where I had a Grizzly Bear walk over 15 meters of clay from which I cast the event. It’s great to know this clay, that has such a history on the Coast, now forms the surfaces on your project.”

George Rammell, sculpture instructor at Capilano College, worked with Bill Reid for 10 years on 14 projects. Their clay was used to make the clay plaster which covers the outside of the City Farmer cob shed.

The ‘West Ender’ newspaper reported at the time: “When completed, the tool shed will have a living green roof, a surrounding bench area and an impressively sculpted cob cooking oven. It will be festooned with a relief sculpture depicting the stratification beneath the topsoil surface: rocks, roots, old fossils, shells and some gnome-like creatures. The door to the structure is a work of art itself, resembling a rounded ship’s hull, and several inches thick.” See here.

The Builder

John Freeman of ERTH Design Consultants built a small garden shed (sculptured building) for City Farmer in 2003 for the enjoyment of all garden visitors. City Farmer is an urban agricultural advocacy group in Vancouver BC teaching composting, organic food gardening, sustainability issues and now green-building techniques. This building is the first cob building in a public space in Canada. “We are starting the seed of green building in the core of the city.”

“The structure is finished with an exterior clay ‘litema’, pronounced DEE TAY MA (African natural plaster) and an interior finish of clay-based plaster (south-western roots). Windows, wood work, floor materials, insulating issues, toxicity, electrical/plumbing integration, living roofs, foundations, doors, arches, structural/seismic concerns are all addressed.”
