during the night." Movable structures were used in 16th century in India by Emperor Akbar The Great. These structures were reported by Arif Qandahari in 1579. In the United States, several companies including Sears Catalog Homes began offering mail-order kit homes between 1902 and 1910. The Forest Products Laboratory, a division of the U.S. Forest Service, put extensive research into prefabricated homes in the 1930s, including building one for the 1935 Madison Home Show. This research continued into the 1960s. By 1958, roughly 10 percent of new houses in the United states were prefabricated. Contemporary domestic prefabrication Currently, the prefabricated housing industry is divided by methodology of construction. Panelized, Modular, and Manufactured home design make up the majority of contemporary firms, with considerable overlap between the construction methods. Panelized homes Panelized homes (also referred to as system built homes), construct the structural components, or "panels", of a home (walls, roof and floor systems) in an off site factory where the panels are cut via automated saws and laser cutters from large wooden sheets, allowing for lower amount of waste compared to site-built construction. Following their cutting and shaping, panels are stacked and delivered to the jobsite where the home is assembled piecemeal in a similar method to traditional site-built home. Panelized homes are generally considered a halfway between more traditional site-built home and more manufactured prefabs, with the flexibility of site-build and efficiency of prefab. Modular Houses Modular houses are built using a system that involves a sequential process in which modern techniques such as 3D digital modeling are now being used, which allows for pre-planning to make the process more efficient. This type of construction is typically up to 50% faster and requires up to 50% less materials than conventional or traditional construction. The size of the global modular construction market is expected to reach USD 271 billion by 2028. North America United States The total market share of non-site built single-family homes (modular and panelized) was at 3% of single-family completions in 2020, according to Census Bureau Survey of Construction data and NAHB analysis. This share is expected to rise moderately in 2021. Europe In the United Kingdom, more than 156,000 prefabricated homes were built between 1945 and 1948. In the 1940s French designer Jean Prouvé designed an aluminum prefabricated house, the Maison Tropicale, for use in Africa. After the World War II until 1948, Sell-Fertighaus GmbH built
