Throughout his career Martin has emphasized sustainable building design, with particular focus on the design, testing, and construction of strawbale buildings. For 10 years he has spearheaded the development of strawbale construction in building codes, most recently with a proposed chapter for the International Building Code. In 2006-07 Martin helped introduce strawbale construction to earthquake-affected Pakistan with Pakistan Straw Bale and Appropriate Building. Since 2010 he has worked extensively in post-earthquake Haiti, including leading an American-Haitian Builders Without Borders team to build the first strawbale building in Haiti. Other sustainable (re)building solutions are being explored, and this Fall the BWB team will begin construction of its school design for the What If Foundation in Port-au-Prince.
