Are you a property developer that is tired of wasting money from low efficiency and slow building construction? Then this might be the article for you!
Modular Construction isn’t a new trend, it’s an idea that has been around for centuries…and for good reason!
From the prefabricated timber trusses of Medieval Europe to Sears’ 20th-century mail-order homes, and even the massive stone blocks and aqueduct systems of ancient civilizations. Building with repeatable, transportable components has always been the smarter, not harder approach. What’s changed today is the scale, precision, and speed made possible by modern technology.
For property developers, modular construction delivers exactly what the market demands: faster project timelines, more predictable costs, and reduced waste…and all without compromising design ambition. In an era where materials and labour have become more expensive, efficiency is no longer optional.
In a world of increasing cost for building materials and resources, our main gains are made through efficiency and time effectiveness.
What is Modular Construction?
The aim of modular construction is to maximise the amount of construction taken place off-site in the prefabrication phase. This includes building elements such as cladding, services, fittings, framework structure and even finishes!
There are many different types and degrees to which modular construction can be implemented and delivered. We will outline the different types below:
This type of modular three dimensional construction offers to deliver structurally complete prefabricated homes, with minimal installation.
I’m sure most people reading this have been to IKEA, this essentially allows prefabricated construction to be delivered in volume and assembled quick
Where flat pack cannot provide the quality that is required, panelled elements can be delivered to site and mechanically fixed together in situ. This method allows for a compromise between Volumetric and Flat Pack modular construction.
Where the project is not entirely modular, particular components can be prefabricated for specialised construction elements. Such as structural components that would otherwise be difficult and not cost effective to build with manual labour.
PROS OF MODULAR CONSTRUCTION
Modular construction can be significantly faster than traditional forms of construction, if planned well. This is one of the benefits of having a controlled environment to fabricate the modules whilst work on site is simultaneously underway.
Building off of the previous point, shorter project timelines are always desired in the construction industry, as it reduces labour costs. Pre-fabrication also saves money by reducing material waste, and increasing efficiency in the construction and assembly phases.
Modular construction is also very scalable in this regard as there is a defined system of production, so even more costs are saved for larger projects.
As pre-fabrication is done in a quality controlled environment, there is less risk for the builder, which means less stress and more time to work on the details. Overall this results in a better quality construction with fewer defects.
Passivhaus standards are much more feasible with this form of construction, as the attention to detail can be engineered in a controlled environment so that thermal performance and air tightness can be achieved at higher standards.
Traditional construction often turns out differently to what is planned, whereas with modular construction, there is a much clearer and defined product presented before placing the order. Similar in the way you would order your kitchen for your local specialist supplier. Once you have paid, you’ll only need to worry about delivery and installation.
Generally modular construction is considered a more sustainable approach to design, due to the controlled environment and rigorous planning methods that go into pre-fabrication. This results in less wastage, higher build quality and better thermal performance. Modular construction is the perfect system for optimised energy efficient homes, and modules can even be disassembled for recycling or reuse.
As modular components are prefabricated off site, there will be less noise pollution, and disruption to urban areas. This makes modular construction of great benefit to urban environments.
CONS OF MODULAR CONSTRUCTION
Quality control in the transportation of the modules must ensure the safe delivery of undamaged modules. For the larger volumetric modules, a higher cost can be expected for transportation, especially for projects located far from the manufacturing facility.
Due to the productised nature of modular construction, although there is some flexibility and customization in the design, there will not be the same level of design flexibility as you would get with traditional construction.
Some property developers may find this type of construction limiting, and may not be suited for clients who have an unorthodox/bespoke vision for their home. Traditional construction allows for more complex methods of construction.
However it is an evolving industry and with the advances in technology and prefabrication methods of construction more complex methods may be possible in the future.
Sometimes access to the site can be quite difficult. For example the site could be located on the main highway or busy road and there is no suitable place to unload modules. Or perhaps the site is located in a remote location and delivery is just not cost effective or even possible without a helicopter.
Additionally weather conditions can cause damage to modules if onsite management is not well thought out. Coordination is essential to ensure the proper storage and logistics of modular components.
Due to transportation and handling constraints there will be limitations to the size of modular units, however this is where the planning and coordination of the individual components comes in. It may require a combination of flat pack and panelised prefabricated components to successfully get the job done.
Modular construction may not be in favour of all local planning authorities, planning officers vary from region to region which may add additional challenges to this method of construction. Additionally local building regulations may need to be adapted for your specific area.
If the fabrication facility is facing delays or transportation, this can have major implications on the timelines and budgets. Also once the design is in order there is very little chance of adjusting the design, which can be a difficult adjustment for many clients who have an inclination to make design adjustments after construction drawings have been issued.
Modular construction relies heavily on the capabilities and capacity of the manufacturing facility and their deadlines.
CONCLUSION
There we have our pros and cons, hopefully giving you the tools to decide whether a modular construction method is best for your next project.
Modular construction is very different to traditional construction, in respect to the fact that an entire philosophical method and approach is needed for it to work. That being said with the challenges in mind, modular construction has many powerful benefits making this a very popular form of construction at all levels.
Modular construction is sustainable. Incredibly efficient, cost-effective and results in high quality thermally performing homes. This industry is developing and growing everyday with new technological advancements being innovated to provide for better homes for the future generations.
This is a revolutionary form of construction that although does not act as a replacement for traditional forms of construction, it is another tool in the box of property developers and designers to produce better homes for a better price.
