The external 'skin' of the building can either be factory fitted or built on-site. Options include timber facings, composite panels, glass, rendering, or more traditional brick and stone. Standard structural wall panels are used, so design effort and expense can focus on the exterior 'skin' of the building. This can result in far better house designs, both in terms of appearance and functionality. The panels are manufactured in a factory, so design and production processes can be fully integrated which means that advanced designs are not compromised by a lack of on-site skills. CADCAM technology allow precision design to be translated into precision manufacture, with any potential problems ironed out before they reach the site.
