What are modular buildings?
Modular construction is a process where buildings are constructed off-site in factory settings using the same materials and designed to the same codes and standards as traditional buildings. However, these buildings are produced in sections known as “modules” which are then transported to the construction site and assembled into a complete structure.
A brief history
The concept of modular construction dates back to the early 20th century, with significant advancements during the post-World War II era. The need for rapid, affordable housing solutions following the destruction of housing stock in the war led to the development of timber-framed prefabricated homes. They were intended as an interim fix which would last about ten years.
Over the decades, technological advancements and increasing demand for sustainable construction methods have refined and expanded modular building techniques. Modular construction today has come a long way since the mid-20th century and has shed the image associated with “prefab” homes; something whose inferior quality was tolerated because it was quick.
Modular building – also known as modern methods of construction (MMC) – is now being embraced by more and more private sector and publicly funded clients, who recognise the benefits in terms of speed, value for money and quality. The approach to modular building today has evolved beyond its origins, where entire prefabs were assembled and transported to their location. More of that in our blog .
What are the benefits of modular construction?
Off-site manufacturing
Modules are built in controlled factory environments, ensuring a higher quality finish, minimal material waste and improved health and safety, which is a . This method also reduces common delays caused by adverse weather conditions as there’s no need to down tools when it rains because you’re in a watertight environment.
Reduced construction time
Modular buildings can be completed up to 70% faster than traditional construction because work to prepare the site and the manufacture of the building can be done at the same time, rather than one followed by the other. Our approach to construction sees plumbing, electrics and ventilation completed in our factory, and the modules joined up on site.
Environmental impact
Modular construction reduces vehicle movements and waste, significantly lowering the carbon footprint of the wider project. Studies also show that waste can be reduced by up to 40%, vastly cutting down on materials going to landfill.
Less disruption
With 85-90% of construction happening off-site, there is less noise, dust and disruption to the surrounding area, benefiting both the environment and local communities. This can be seen in particular in the number of lorry movements to and from the site, which is often the biggest complaint from residents and businesses living near a construction project.
Sustainability: The environmental benefits of modular construction
At Enlight10, we believe very strongly in the need to think about our environmental impact at every stage of the building. This involves everything from considering the embedded carbon in the materials we buy to emissions from our factory to the transport of completed modules to site. Here’s more about the environmental benefits of modular construction.
Greater flexibility and re-use
Modular buildings can be disassembled, relocated or refurbished, reducing the need for new raw materials and minimising energy expenditure.
Less material waste
Building in a factory makes it easier to recycle materials, control our inventory and protect building materials from damage, resulting in significantly less waste.
Improved air quality
Constructing modules in a dry, controlled environment eliminates the risk of moisture-related issues, improving the air quality of the finished building.
Types of modular construction
There’s more than one approach to modular construction and the choice will depend on the needs of the client. The two main types are permanent modular construction (PMC) and relocatable buildings.
Permanent modular construction
PMC involves creating permanent buildings using prefabricated modules. These can be integrated into traditional construction projects or stand alone. PMC offers high-quality control, less waste and faster completion times.
Relocatable buildings
Relocatable buildings (RBs) are designed for multiple uses and can be transported to different sites. They are ideal for temporary needs such as classrooms, construction site offices and medical clinics. RBs provide fast delivery, ease of relocation and flexibility in design and function.
How long do modular buildings last?
As we said earlier, this method of construction is longer about meeting a need as quickly as possible with an inferior product. MMC is a real alternative to traditional construction, which is every bit as good in terms of the quality and robustness of the finished project.
Modular buildings, when constructed and maintained properly, can last as long as traditional buildings. The materials and methods used in modular construction meet or exceed the same building codes and standards, ensuring durability and longevity.
Who uses modular construction?
Modular construction is utilised across various sectors. Here are some examples:
- Education: Classrooms, nurseries, gyms, dining halls and administrative offices
- Healthcare: Medical clinics, hospitals and specialty care units
- Corporate: Office buildings, meeting rooms and workspaces
- Housing: Temporary and permanent housing solutions
- Retail and leisure: Stores, cafes, recreational facilities and more
The flexibility, speed and sustainability of modular construction make it an attractive option for diverse industries seeking efficient building solutions. We are working with many government departments and executive agencies who have switched on to the benefits of modular construction but it is particularly prominent in high rise developments too.
Modular construction represents a forward-thinking approach in the building industry, offering numerous benefits from reduced environmental impact to faster construction times. Its adaptability and efficiency make it a preferred choice for many sectors looking to innovate their building processes.
