Persimmon has entered the government's £60,000 house challenge in partnership with Fusion Building Systems (UK) and PRP architects. Since the government announced the official start of its so-called Design for Manufacture competition, the team has been working on building a prototype low-cost steel frame dwelling as part of Persimmon's MMC project at Irlam, Greater Manchester, where four new homes are being built using different modern methods aimed at focusing on speed of build and reducing on-site waste.
