William Lishman is a very smart man with too many titles to name (check his personal site here). After living in a what most people would call a standard looking house, he decided to design a more eco-friendly house – partially underground. He thought it would be a good way to save on energy costs.
In 1990, Lishman had the idea to build a set of spaces underground similar to large onions linked together by passageways just west of Peterborough, Ontario. Each space represented a different living area. For natural light, each space, or onion, was given a skylight. He also put air ducts for ventilation and plumbing. On top of it all are roof gardens where he to plant vegetables and fruits.
One major significance of Lishman’s curvaceous submerged design is that it is easy to illuminate, compared to
rectangular underground spaces which tend to have darken interior corners. Another major advantage is that the
wall, ceiling and roof all act as one entity, creating a type of organic worldsheet. The earth
surrounding the house provided Lishman with the heating, cooling and insulation.
