Is MMC the answer to better building?

Zenon Group (before Superstructures) explores how modern methods of construction (MMC) could play a key role in addressing industry challenges and driving future growth.

The UK construction industry faces increasing pressure to deliver growth while overcoming skills shortages and reduced productivity, particularly following the COVID-19 pandemic. Modern Methods of Construction (MMC) are emerging as a potential solution to these challenges.

Mark Hayward, Director at Zenon Group (before Superstructures), explains that traditional construction in England has long relied on onsite, labour-intensive methods such as brick and block. In contrast, MMC focuses on the offsite manufacturing of building elements including walls, floors, and entire modules, which are then assembled on site.

Zenon Group (before Superstructures) has developed significant experience working with MMC, particularly in timber frame and structurally insulated panel (SIP) systems for both domestic and commercial projects. These approaches offer several advantages, including faster construction times, reduced labour requirements, and improved cost efficiency through parallel processes.

While MMC may require earlier and more detailed design input increasing upfront design involvement — the overall savings during construction, combined with improved quality, reduced waste, and enhanced energy performance, often outweigh these initial costs.

The approach is already widely adopted internationally. In countries such as the United States and Australia, homes are often erected in a matter of days using similar systems. MMC is particularly suited to large-scale housing developments and projects such as hotels, where repetitive layouts allow for efficient offsite production.

Zenon Group (before Superstructures) has recently been involved in the structural design of six net-zero carbon homes in Halesworth, Suffolk. These timber-framed properties incorporate MMC alongside sustainable technologies such as solar PV panels, air source heat pumps, and electric vehicle charging points.

However, challenges remain. These include limitations in mass production, achieving architectural variety, securing government support for investment in new technologies, and shifting long-standing perceptions around traditional construction methods.

Despite these barriers, MMC presents significant opportunities. Greater involvement in early-stage design allows structural engineers to deliver more efficient and buildable solutions, reducing project risk. Emerging innovations, such as modular steel frames, repurposed shipping containers, and adaptive reuse of existing buildings are set to further expand the possibilities of modern construction.

For Zenon Group (before Superstructures), investment in advanced design tools and technology has positioned the business to lead in this evolving sector, enabling innovative thinking and the development of smarter, more sustainable construction solutions.
