Housing: Modern Methods of Construction

Lord Mair Excerpts

Thursday 5th September 2024 Lords Chamber

[Lord Mair (CB)]

My Lords, I declare my interests as a civil engineer, both in practice and as an academic, at Cambridge University, and as a consultant to Laing O’Rourke, the company that pioneered MMC in the construction industry. I am currently a member of the House’s Select Committee on the Built Environment; I was not a member when that committee, chaired by the noble Lord, Lord Moylan, undertook its short inquiry on MMC for housing, culminating in its excellent letter to the Government.

However, I was a member of the Select Committee on Science and Technology, which in 2018 undertook an inquiry highly relevant to today’s debate, its report being entitled Off-Site Manufacture for Construction: Building for Change. That report concluded that off-site manufacture, synonymous with MMC,

“provides clear and tangible benefits which make a compelling case for its widespread use”.

Recognising these benefits, in the Autumn Budget of 2017 the Government announced a “presumption in favour” of off-site manufacture for five specific government departments: transport, health and social care, education, the MoJ and the MoD. Significantly, that presumption in favour was not stated as applying to MHCLG. For infrastructure generally, there have been many success stories: high-rise buildings, hospitals and schools are increasingly being built with MMC, demonstrating excellent design, significantly faster and higher-quality construction, and less waste.

The Science and Technology Committee heard that a significant barrier to MMC for house construction at scale was the need for longer lead times: the housebuilder has to commit to a production schedule well in advance of actual unit sales, risking that market conditions might deteriorate. This and other barriers could be overcome if there were a substantial guaranteed pipeline of MMC housing across the country—the point made by the noble Lord, Lord Carrington of Fulham. My question for the Minister is therefore this: should not MHCLG—and Homes England—confirm its wholehearted support and announce forthwith a presumption in favour of MMC, as five other government departments have done?
