Lloyd is a Past President of the Architectural Conservancy of Ontario.

In the course of his work developing small residential units and prefabs, Lloyd became convinced that we just use too much of everything- too much space, too much land, too much food, too much fuel, too much money, and that the key to sustainability is to simply use less. And, the key to happily using less is to design things better.
