Facit Homes is one of the first companies in the world to digitally fabricate and manufacture an entire house on-site. The company's patented D-Process uses a compact, high-tech machine to turn a 3D computer model into exact physical components that can be snapped together like LEGO bricks. Facit Homes’ D-Process was shortlisted as one of 60 finalists for the 2013 Index: Award.
Using D-Process, Facit Homes designs each building on a computer in extremely detailed pieces which are then cut on a CNC router. The building components are shaped into LEGO-like cassettes and are usually made from plywood, which is light enough to be easily assembled on-site. Thanks to the high precision of the process, costs and material waste are kept to a minimum.
Each home includes a thermal envelope that makes sure the house is air tight, conserving energy and minimizing heat loss. Depending on the site requirements, an array of supplementary environmental systems such as solar thermal systems and photovoltaic panels can be plugged into the building to make it perform more efficiently.
Houses like Villa Asserbo in Denmark and the Hertfordshire House in the UK are just a few successful examples of homes built using the on-site D-Process. In the case of the 200-square-meter Hertfordshire House, the home’s heating system has the equivalent output of a single 4kW radiator, while the layout of the Villa Asserbo, built from 800 sheets of sustainable plywood, takes advantage of natural light and surrounding views.
