The goal of OFFGRID-INSTYLE is to develop a range of energy-efficient and affordable home designs, including detailed construction drawings and materials order lists, which can be purchased online so that they can be easily and economically built just about anywhere in the world.

All drawings are prepared by accredited building designer David Macfarlane, whose formal qualifications include a Building Certificate (Sydney Tech), BSc Architecture (UNSW), and MSc in Sustainable Building Design (Oxford Brookes).  Completed projects include Tamar Solarhome in northern Tasmania, plus one of Australia's first purpose-built solar-powered off-grid resorts, now trading as Elysian Island Retreat on one of the Great Barrier Reef islands.

OFFGRID-INSTYLE  and TAMAR SOLARHOME are owned and operated by Ecoventure Pty Ltd.  Managing director David Macfarlane can be contacted at:
