Bella & Richard Walker

Bella and Richard are designers of earth buildings and have held many earth building workshops in both the North and South Islands of New Zealand during the past 23 years. Their former home in Todd Valley was the first adobe house with load bearing walls to receive a building permit in New Zealand in recent times and helped initiate a revival in earth building in New Zealand.

Richard is a consulting registered engineer with 35 years experience in the design and construction supervision of large and small scale projects in both New Zealand and overseas. He prepared the draft for the New Zealand Standard for earth buildings not requiring specific design and has done the engineering design for approximately 100 new earth houses in New Zealand including those in adobe, cob, rammed earth and wattle and daub.

Bella and Richard were awarded the Elizabeth Drupsteen Memorial Award in 1997 for their outstanding contribution in promoting earth building.
