The market for made-to-measure prefabrication systems is growing, bringing several benefits in terms of quality, precision, and speed of execution on-site, but this type of construction necessitates meticulous upstream planning. The construction sector faces many challenges, with increased regulatory performance, a very competitive market with tight deadlines and budgets, increasingly complicated land in urban areas, and difficult access. In this context, the dry sector and off-site sites are developing. Large and complex building elements are increasingly machined and assembled in a workshop or factory, up to complete pre-equipped 3D modules. The benefits are numerous. Work in the warehouse building is easier to control in terms of quality and precision, generates less scrap and waste, can be recycled, and improves working conditions. The sites are cleaner, less noisy, more meticulous, and the time savings can be counted in months. A varied architecture Prefabrication can be
