Prefabricated Modular Construction

Manufacture, certification, testing and deployment of unique prefab home systems

A21 practice has developed a number of construction systems to create permanent buildings that can be produced on a production line in a factory, fitted-out using materials appropriate for their final use as a building. We have developed IP on all critical aspects of the design, tested components and obtained full system certification.


Subsequently, this system was employed in the construction of various projects, such as a fully equipped hotel building, en suite pods for a hotel, and a 9-unit residential development. The residential project was carried out for Broadland Housing in Norwich and received Building Research Establishment BRE LPS 2020 certification.


LPS 2020 is a standard for manufacturers of innovative systems, elements and components for constructing residential buildings. It provides manufacturers with a one-stop certification route to meet requirements agreed with insurers, lenders and regulators. Further information on this can be found on the BRE website.
