The accessible nature of straw bale building lends itself well to self-built and workshop-built housing; straw is

arises as to whether or not hiring an experienced builder can reduce overall costs of such a structure. This study
conducts a worldwide survey to straw bale home owners to answer this question and to determine general
economic data on straw bale homes, such as: what home owners value, who the main builder typically is, and
what usually causes budgets to overrun. A key finding is that self-building is economically justified if the
projected saving is higher than the cost of a contractor and if the usually longer time needed to build the home is

building standards. A key observation is how demanding any specific building phase is in comparison to
