As simple as these designs may appear, hundreds of hours, many thousands of dollars, and more than fifty years' building and design experience have gone into researching, developing, prototyping, and perfecting them – including selecting the most economical components and materials, testing ideas and designs in practice, simplifying construction details to minimise labour, and adjusting dimensions to suit standard component sizes in order to minimise cutting and waste.
