Algeco UK OSS has shared behind-the-scenes images of its latest 75-bedroom Single Living Accommodation (SLA) complex at the Ministry of Defence (MOD) Stafford. The company has delivered a full turnkey solution, acting as Principal Contractor to the Defence Infrastructure Organisation (DIO) and the British Army.

Modern Methods of Construction (MMC) refers to offsite and onsite techniques, which could include mass production and factory assembly as alternatives to traditional building methods. These are a fast way of delivering new buildings focused on the efficiency of materials and human resources.  Modular buildings devised utilising MMC have the potential to deliver significant improvements in productivity and quality for both the construction industry and the end user. They also minimise the work required on-site, which can have added benefits and appeal for those in sectors such as Defence.

The solution provided to MOD Stafford is a CTM Leve1 (Category 1) Pre-Manufacturing 3D primary structural system that will be used to house members of the army. The three-storey building, known as Beacon Barracks, is set to offer high-quality accommodation with integral communal areas, as well as a brick slip façade and sustainable features including solar PV and heat pumps. The modules for the barracks were manufactured in Carnaby in East Yorkshire and delivered to the site with a Pre-Manufactured Value (PMV) of around 80%. MOD Stafford was designed by AHR Architects, supporting the Algeco UK OSS team on the construction stage and architectural design through its Leeds offices.

A full site inspection has now been carried out with strong feedback received by attendees and participants, particularly regarding the overall quality and feel compared to comparative schemes.  Volumetric Air tests are carried out on all completed projects and the SLA Block at MOD Stafford has achieved a rating of 1.18. Lee Kenton of Build Energy commented that 1.18 is “exemplary for the size of the building” and “far exceeded” the Passivhaus gold standard of 0.60, with an air change rate of 0.48.

The new barracks at MOD Stafford is part of an £800M investment into SLA by the Army over the next decade. This investment into modern infrastructure is set to provide military personnel with the fit-for-purpose accommodation facilities they deserve, as well as contribute to ambitions to become Carbon Net Zero by 2050.

Brigadier Pete Quaite, head of army infrastructure plans, said: “I visited the Single Living Accommodation under construction at Beacon Barracks at the start of this year. To see the finished block just two months later shows the impressive pace of progress being achieved through our modular design and build programme. This new SLA is another excellent example of how ongoing Army investment is improving the quality of life for our people, providing them with modern, spacious and well-designed accommodation.”

Wayne Yeomans, Algeco UK OSS sales and marketing director, added: “This is modular and offsite construction at its best. I must applaud the Algeco UK team as well as our supply chain partners, including AHR Architects, for making this possible. Working with architects means we have incorporated innovative features into the design, such as solar PV orientation to maximise the amount of electricity produced and optimising the number of overall modules required.

“We were selected as the modular building partner by the MOD because of our track record in supplying high quality accommodation on a diverse range of other publicly funded projects, along with our willingness to collaborate with project partners and deliver excellent value for money. “The quality of these solutions is proven by results, like the industry-leading scores achieved in our recent volumetric air test, which is not an easy achievement. We have learnt so much from this project and we are proud this will also help inform the Defence Infrastructure Organisation’s future Programmatic Design approach.”

The report “Modular Construction Market by Type (Permanent, Relocatable), Module, Material (Wood, Steel, Concrete), End-Use Industry (Residential, Office, Education, Retail & Commercial, Hospitality, Healthcare), Region – Global Forecast to 2029” estimated the global modular construction market size will grow from USD 104.1 billion in 2024 to USD 140.8 billion by 2029, at a CAGR of 6.2% during the forecast period.

The modular construction market is growing rapidly due to urbanization, population growth, and the need for faster, more efficient building methods. Technological advancements have enhanced the quality and customization options of modular buildings, making them increasingly popular. Additionally, the focus on sustainability drives the adoption of modular construction, which generates less waste and requires fewer resources compared to traditional methods. However, factors such as lack of awareness and volatility in transportation charges may stall the growth of the market.

Permanent modular building is estimated to dominate the market

The modular construction market is categorized as permanent and relocatable. Permanent modular buildings are reported as having the largest market share in the modular construction market. Permanent modular construction saves time and labour, thus lowering the construction cost.

Steel is projected to be the fastest growing segment in the modular construction market

Steel is the fastest-rising segment for the modular construction market from 2024 to 2029, in terms of value. This is because of the increasing use of steel in construction activities. Steel is also lighter in contrast to other materials, which makes it easy to be craned and transported into a place in a more efficient manner, resulting in less disturbance to the local area.

The residential segment is expected to dominate the modular construction market.

Residential building structures can be built using modular construction solutions in about half the time as compared to conventional site-built construction methods. Different countries are turning to the adoption of modular construction methods as the modular construction helps in waste reduction during the construction process as the different modules are made in-factory. The residential end-use industry reported the most substantial demand for modular construction in 2023, in terms of value and volume.

Asia Pacific is the largest market for modular construction.

The Asia-Pacific (APAC) region emerges as the largest market in the modular construction industry among APAC, North America, Europe, the Middle East & Africa (MEA), and South America, primarily due to several key factors. Construction, one of the biggest and most valuable manufacturing sectors in the region, is highly fragmented and consists of a considerable number of large, medium-sized, and small construction companies. The construction players in the industry have adopted various technologies as a strategy to sustain the growing demand and competition. Rapid urbanization, industrialization, and expanding middle-class populations in countries like China, India, and Southeast Asian nations contribute significantly to the region’s dominance in the market. Furthermore, increasing urbanization has led to changes in lifestyle and consumption patterns, driving the need for independent housing units.


TG Escapes provide timber frame, net-zero buildings offering a highly flexible, bespoke, turnkey, architectural design and build solution to a wide range of customers. Biophilic design principles are combined with sustainable materials and the latest technology to create buildings that are beautiful, ergonomic and inspiring for their occupants whilst offering exceptional environmental integrity. One of their more recent projects was commissioned by Brune Park Community School which is part of the Gosport and Fareham MAT.

The school needed to replace an old SCOLA building, which had poor insulation values and provided an uncomfortable learning environment. They selected TG Escapes to design a building providing flexible classroom space, including conferencing facilities to also act as a local community business hub. The building includes nine classrooms which can be opened up, breakout and office spaces and a large atrium.

GFM were keen on an operational net-zero solution and were impressed by TG Escapes understanding of their requirements. They also considered a volumetric and traditional build but the timescales didn’t suit. The building, completed in 26 weeks onsite, achieved an A+ EPC at minus 3 at a cost of £2.8m including demolition, temporary construction and external landscaping.

Kevin Rochester, Head of Estates at GFM says;

“The green aspect is a big plus for us now that we are trying to move into the world of sustainability. We also just felt in the commissioning process TGE were really enthusiastic about the project as a flagship building whereas the others seemed to see it as just another project. The other buildings were also fantastic but TGE had the eco thing and the chemistry was right.”

Andrew Cowlard, Associate Director at MEB Design acted on behalf of GFM as contract administrators;

“I found that it was very positive because in our role, a traditional job is a lot more involved. And because TGE offers a one-stop-shop solution with their own project management, they almost manage it all themselves so there was less involvement required from my side. Overall it was quite seamless.”

Kevin Rochester;

“I am delighted with our experience of TG Escapes, from the initial tender exercise right through to the successful completion of the build. They have maintained an exceptional standard of communication throughout the project which has facilitated a smooth collaboration. Their prompt and professional response to queries has significantly contributed to the efficacy of the entire process and we commend TG Escapes for their unwavering dedication to adhering to the project timeline.

Operating within a bustling school environment, the absence of conflicts between the contractors and the broader GFM School community is a testament to their ability to seamlessly integrate their operations. The meticulous attention to detail is evident and speaks to their commitment to excellence. Their team’s courteous and respectful demeanour has made collaboration a true pleasure.”

At the recent opening of the building, senior staff and board members commented;

“We have both single classrooms and open classrooms enabling us to teach in creative ways. The large amounts of glass and open plan spaces allow us to see the outside and bring that outside into the classroom which is always really positive for mental health and well-being.”

“It is also an eco-friendly building that sustains its temperature, provides a sustainable environment for learning and creates a space that people actually want to learn in.”

“This building is very special, it is a landmark in Gosport already and it will certainly be a focal point for Brune Park School.”
