Prefabs sprouting: Modern Methods of Construction and the English housing crisis
Lead Research Organisation:

Abstract
The UK Government is once again embracing the 'prefab'. However, rather than the iconic bungalows of the post-war housing emergency, or the ageing concrete tower blocks that still dominate many urban skylines, today's offerings are digitally designed and manufactured in controlled factory settings. In 2019, the Government - keen to accelerate housebuilding, reduce carbon emissions and challenge the traditional construction sector - began to commit significant resources to this method of housebuilding, what is usually called 'Modern Methods of Construction' or MMC. They did this, in part, because of the ongoing 'housing crisis' whereby an insufficient supply of good quality, affordable homes for sale and rent has driven up the numbers of people living in insecure, poor quality and temporary accommodation. However, there is little research being done to understand what kind of homes and places MMC firms are building or what role MMC is playing or should play in addressing the housing crisis.
Our project will fill this gap and is organised around three main tasks. Firstly, we will build a picture of the MMC sector in England. Second, we will study what kind of homes and places MMC developers have delivered. Third, we will analyse how policymakers and the housing industry are changing or responding to the emergence of MMC. Part of the study works at the national level to understand what is happening with MMC across England. Another part of the study is anchored in case studies of MMC-driven housing regeneration to gain first-hand knowledge of how MMC projects are delivered and experienced by residents.
Our project brings together researchers working in housing studies, geography, architecture, civil engineering and project management and our methods include documentary analysis, interviews, ethnography and GIS mapping. Our study will enable us to deliver new data of benefit to: scholars interested in housing justice, technical standards, safety and sustainability; government policymakers hungry to address the housing crisis and understand the impact and trajectory of MMC; MMC firms looking for best practice and to publicise their innovative approach to construction; housebuilding industry professionals looking to better understand MMC; civil society organisations who want more information about this new industry and its impacts; the general public who want insights into the reality of buying and living in a modern 'prefab' home and housing activists who are looking for an alternative housing system that works very differently from what we have now.

| Description | The study identified 215 residential housing schemes in England, completed or in progress, where MMC-specialist firms are explicitly named as delivery contractors. Ninety-four of these are being delivered for private developers, 70 for social housing providers, 41 for local authorities and 10 for non-profit providers. We estimate that 134 of the 215 schemes we identified have been completed to date equating to 8,096 homes built using MMC. Critical factors in the viability of MMC firms and the effective delivery of housing schemes, according to our findings, include: securing a stable pipeline of housing demand, optimising alignment between production and installation process, expending sufficient up-front R&D investment, achieving a critical balance between standardisation and customisation of product, and investing in project management expertise. There are wide variations in the quality of MMC homes, according to residents. We found many residents are happy with their home and found little evidence of stigma or anxiety about living in an MMC home. However, residents in some schemes expressed significant concerns over the finish of their homes, reinforced by poor aftercare services, especially around snagging lists. This created reputational damage in some cases. There remain significant gaps in available independent evidence regarding the quality and outcomes of MMC housebuilding, not least around residents' post-occupancy experience. There also remain significant gaps in evidence around jobs and conditions within MMC factories and how to address skills gaps in the advanced manufacturing sector more generally. Existing regulatory frameworks for residential construction do not take sufficient account of the specificities of 'modular' housebuilding, not least around the testing and certification of MMC products, or around fire performance. If the MMC sector is to help address the catastrophic social rental housing crisis in England, government needs to bring forward a wide-ranging strategic framework taking account of the specific financing, land availability and regulatory demands that come with building via MMC. The MMC sector is not a 'magic bullet' for solving a housing crisis which has developed from long-term systemic dysfunction. Operating within this dysfunction, start-up MMC firms have had little margin for error, brutally exposing, in some cases, strategic and operational mistakes. Without wider systemic reform, MMC firms could become part of the dominant housebuilding model, merely helping to bring supply chain efficiency to an unacceptable status quo. |
| Exploitation Route | Interest in MMC remains high as a potential solution to productivity issues in the construction sector. However, extensive further research is required to more fully understand the quality and performance of MMC homes, the experience of residents, the pay and conditions offered within MMC factories, and the regulatory and safety landscape around MMC products. In other words, our study introduced questions of social and housing justice to the MMC sector and these should be sustained by researchers. |
