In this blog, we delve into the emerging trends in the UK residential market and explores their potential to shape the future of housing.
THE NEED FOR MODERN METHODS OF CONSTRUCTION
Historically, the UK's residential construction industry has relied on conventional practices of using brick, mortar in combination with timber and/or steel, involving onsite building processes, and extensive manual labour. While these methods have contributed to the development of countless homes, they come with significant drawbacks in the modern context.
Firstly, traditional on-site construction is time-consuming. Projects are often delayed due to various factors, including adverse weather conditions, material shortages, labour unavailability, cow-boy behaviour of available labour etc. These delays not only hinder the timely delivery of housing, but also contribute to increased costs, making homes and refurbishments less affordable for potential buyers and investors.
Secondly, the cost of traditional construction has been on the rise over the years. Factors such as fluctuations in material prices, stringent regulations, and the labor-intensive nature of onsite construction all play a role in escalating expenses.
Moreover, traditional construction methods have a substantial environmental impact. The amount of waste generated during the construction process is significant, contributing to landfill pollution and resource depletion. Additionally, the energy consumption associated with traditional construction contributes to greenhouse gas emissions, exacerbating climate change challenges.
The need for a paradigm shift in the construction industry is becoming increasingly evident. Embracing innovative construction methods offers several advantages that address the limitations of traditional approaches. All other industries have moved from labour-intensive approaches to a more manufacturing-based approach.
One of the primary advantages of adopting new construction methods is the substantial reduction in the carbon footprint. Sustainable construction practices, such as the use of eco-friendly building materials and energy-efficient designs, can significantly minimise a building's environmental impact. As concerns about climate change intensify, such sustainable practices are crucial in mitigating the industry's contribution to greenhouse gas emissions.
Furthermore, new construction methods promise faster project delivery. By utilising efficient construction processes, such as off-site manufacturing and modular construction, developers can significantly reduce construction timelines. This not only meets the urgent need for housing in a timely manner but also lowers costs associated with prolonged construction periods.
Another significant benefit of embracing new construction methods is the potential to improve housing affordability. By streamlining construction processes and reducing costs, developers can offer more competitively priced homes to buyers, making homeownership more accessible to a broader segment of the population.
MODERN METHODS OF CONSTRUCTION (MMC)
The concept of Modern Methods of Construction (MMC) has gained momentum in the UK residential market due to its potential to revolutionise the construction industry. MMC involves the off-site manufacturing and assembly of building components in controlled factory settings. These components are then transported to the construction site for final assembly.
One of the most prominent techniques under MMC is modular construction. In this method, buildings are constructed in sections or modules off-site, then assembled to form the final structure onsite. Modular construction offers numerous advantages, including:
-
Speed:
Off-site manufacturing allows for simultaneous construction activities, significantly reducing project timelines.
-
Quality Control:
Factory conditions ensure consistent quality of building components, minimising defects and rework.
-
Reduced Disruption:
Onsite activities are minimised, leading to less disturbance to local communities during construction.
-
Cost Savings:
Efficiency in material usage and labor contributes to cost savings.

The new-build residential construction market in UK is witnessing a significant shift towards Modern Methods of Construction (MMC) to meet the demand for more efficient, sustainable, and cost-effective building practices. Some of the methods accepted in UK are below:
-
Modular Construction:
Modular construction involves the off-site manufacturing of building components, known as modules, in a controlled factory setting. These modules are then transported to the construction site for assembly. Modular construction is highly versatile and can be used for various building types, including residential, commercial, and educational structures. It offers several benefits, such as faster construction timelines, reduced waste generation, and improved quality control. The ability to simultaneously manufacture modules off-site while site preparation is underway contributes to faster project delivery and reduced finance costs.
Some key large scale industry players in this space are Laing O'Rourke, Offsite Solutions, Portakabin, Elliott Group, Elements Europe, Caledonian Modular, etc.
-
Panelised Construction:
Panelised construction is similar to modular construction but involves the off-site manufacturing of wall panels, roof trusses, and floor systems. These panels are then transported to the construction site and assembled to form the building's structure. Panelised construction is well-suited for projects with repetitive designs, such as housing developments. It offers faster construction times, reduced labor requirements, and enhanced consistency in construction quality.
Some of the major players are SIPCO, Kingspan, Stewart Milne Timber Systems, B&K Structures, Fusion Building Systems etc.
-
Cross-Laminated Timber (CLT) Construction:
CLT construction involves the use of cross-laminated timber panels as load-bearing structural elements. CLT panels consist of multiple layers of wood boards stacked at right angles and bonded together with adhesive. CLT is a sustainable and eco-friendly building material, as it sequesters carbon and requires less energy to produce compared to traditional construction materials like concrete and steel. CLT construction is popular for low-rise and mid-rise buildings and offers advantages such as faster construction times and reduced environmental impact.
Some largescale providers are KLH UK, B&K Structures, Stora Enso etc.
