Residential construction, in particular high-rise buildings, promise to be one of the biggest businesses of the future. House erection, especially for high-rise buildings, is a key issue. Several Japanese companies have developed innovative systems during the last decade. The SMART system, developed in 1992-1994 [24], was the first one. It was used for the construction of more than 30 stories. It consists of an all-weather, full-robotic factory on the top of the building. The lift-up mechanism automatically raises the construction plant. The continuation of this effort is the IF7 Japanese [25] and FutureHome EU projects [26].
