designIT is a software tool for all building practitioners to design houses and similar structures using Engineered Wood Products, manufactured by CHH Woodproducts in correlation with other selected materials. Quick and simple to use, yet deceptively powerful software, designIT for Houses is useful for the selection of beam sizes without the need for engineering knowledge or the exercise of professional engineering judgment.
