Simon Tilley, a chartered mechanical engineer, joined Hockerton Housing Project in 1995 after a background in manufacturing and sustainable development work. This included spending two years in Namibia working for Voluntary Services Overseas (VSO). His engineering skills have been put to good use in the project, designing and adapting the energy and water systems, as well as being a key player in the development of low-impact, affordable, earth-sheltered houses.
