Abstract
Purpose
The purpose of this study is to gain insight into procurement routes and forms of contract used for volumetric offsite manufacturing (VOSM) in the housing sector of the UK West Midlands. Seminal literature and government reports have established the potential of offsite technologies to improve the supply of quality housing in the UK. However, the lack of a structured procurement route, common to manufacturing approaches in construction, has significantly contributed to delays in large scale adoption.
Design/methodology/approach
To achieve the research intention, an exploratory study was undertaken. A literature review of seminal literature and government papers was conducted to establish and benchmark current trends in context. Data was collected using focus groups and interviews with a housing association and housing VOSMs. Grounded theory was used to analyse data and inductively generate themes leading to an original procurement model. The issues identified in the delivery of volumetric housing were categorised into three themes.
Findings
The findings suggest a limited familiarity with offsite manufacturing (OSM) by housing providers. Albeit, a willingness to adopt these technologies to deliver housing were demonstrated by trial attempts. However, due to limited knowledge, the approach to procurement is by adapting existing procurement models, which are not ideal and obstruct the potential benefits of using offsite technologies primarily because of the significant difference in processes. Also, geographical location influenced procurement decisions when comparing cost with conventional procurement and the dearth of specific government incentives to deliver housing using offsite technologies. This study proposes a procurement model for VOSM.
Practical implications
The results have implications for decisions about procurement routes and contractual terms used by housing providers delivering volumetric offsite manufactured housing at scale. Although this study focussed on the West Midlands region, most of the issues identified were not geographically unique.
Originality/value
This study contributes to the existing body of knowledge on potential barriers to the adoption of OSM in the housing sector of the UK. The findings will be of value to stakeholders involved in delivering housing and offers a useful contextual basis for future research.

Abstract
Purpose
Housing provides constructed space for human activities. Literature indicates that housing impacts wealth, education attainment and health outcomes, among others. Because of its contributions to society, it is essential to develop and implement strategies that address the housing shortage experienced in most cities across the globe. This study aims to unpack the factors affecting housing production in the UK and chart the way forward.
Design/methodology/approach
In addressing this study's aim, an interprivitst approach was adopted and semi-structured interviews were conducted with 18 experienced professionals. Data were collected across the four nations of the UK (England, Wales, Scotland and Northern Ireland).
Findings
The results indicated that the opportunistic behaviour of stakeholders is one of the main factors affecting housing production in the study area. Also, modern construction methods, collaborative practices, government intervention and affordable housing schemes were identified as key strategies for addressing housing production factors.
Practical implications
This study identified strategies for mitigating housing production issues that provide a focal point to all stakeholders keen on filling the housing shortage gap and improving productivity to channel their resources and effort accordingly.
Originality/value
To the best of the authors’ knowledge, this study is one of the first to empirically analyse the influencing factors on the housing gap in the UK from the perspective of the supply side to provide information that could lead towards closing the said gap.
