The Advantages and Differences of Modular Construction

As an expert in the construction industry, I have seen the rise in popularity of modular construction and the confusion surrounding its various names. Terms such as “off-site construction”, “prefabrication” and “modular construction” are often used interchangeably, causing confusion for those not familiar with the industry. In this article, I will explain the different names for modular construction and their meanings, as well as the advantages and differences between modular and traditional construction methods.

What is Modular Construction?

Before diving into the different names for modular construction, it's important to understand what it actually is.

Modular construction

involves producing standardized components of a structure in an external factory and then assembling them on site.

This method is often used to create large modules that are designed to be joined together, resulting in a more efficient and cost-effective building process.

Prefabricated vs. Modular Construction

One of the most common misconceptions is that prefabricated and modular construction are the same thing. While they are both forms of off-site construction, they are not exactly the same.


refers to the prefabrication of building components off-site, in a specialized facility.

This can include walls, floors, and other flat components that are then transported to the site for assembly. On the other hand, modular refers to large modules that are built off-site and designed to be joined together on site. In other words, all modular buildings are prefabricated, but not all prefab buildings are modular. This distinction is important to understand when discussing different names for modular construction.

Other Names for Modular Construction

Now that we have a better understanding of what modular construction is, let's explore the different names that are often used to describe it.

Off-Site Construction

As mentioned earlier, off-site construction is a broad term that encompasses both prefabricated and modular construction. It simply refers to any construction that takes place outside of the actual building site.

This method has gained popularity in recent years due to its ability to reduce construction time, waste, and potential cost savings.


Prefabrication is another term that is often used interchangeably with modular construction. However, as we now know, prefabrication can also refer to the production of building components off-site. This term is more general and can include various methods of off-site construction.

Kit Construction

Kit construction involves pre-cut parts that require significant assembly on site, but with minimal waste. This method is often used for smaller structures such as sheds or garages.

Temporary Construction

Temporary construction refers to buildings that are designed to be easily moved or dismantled.

This can include structures that are used for events or temporary facilities such as bathrooms or washbasins.

Panelized Construction

Panelized construction is a more efficient form of construction in which walls, floors, and other flat components arrive in large sections that can be quickly placed in place. This method is often used in conjunction with traditional construction methods.

Volumetric Modular Construction

Volumetric modular construction is the most complete form of modular construction, with a minimum of on-site assembly required. This method involves building 3D volumetric structures in factories and then transporting them to the site for installation.

The Advantages of Modular Construction

Now that we have a better understanding of the different names for modular construction, let's explore the advantages of this method compared to traditional construction.

Reduced Construction Time

One of the biggest advantages of modular construction is the reduced construction time. Since the majority of the building is constructed off-site, there is less time spent on the actual building site.

This can result in significant time savings, especially for labor-intensive projects.

Cost Savings

In addition to saving time, modular construction can also result in cost savings. This is due to the efficiency of building in a controlled factory environment and the reduced labor costs associated with on-site construction.

Reduced Waste

Modular construction also produces less waste compared to traditional construction methods. This is because the building components are produced in a factory setting, where materials can be more accurately measured and utilized.


As the construction industry continues to prioritize sustainable and efficient methods, safety is also a major advantage of modular construction. With less on-site work required, there is a reduced risk of accidents and injuries on the job site.

Real Examples of Modular Construction

To better understand the different names for modular construction, let's look at some real examples of prefabricated and modular buildings.

Clayton Homes

Clayton Homes is a popular modular home company that offers customizable homes built in a factory setting.

These homes are then transported to the site for installation, resulting in a faster and more efficient building process.

Champion Homes

Similar to Clayton Homes, Champion Homes offers customizable modular homes that are built in a factory and then transported to the site for installation. This method allows for more control over the building process and can result in cost savings for the homeowner.


Boxabl is a company that specializes in volumetric modular construction. They offer customizable, stackable units that can be used for a variety of purposes, including residential and commercial buildings.

In Conclusion

As an expert in the construction industry, I have seen the benefits of modular construction firsthand. While there may be confusion surrounding the different names for this method, it's important to understand the distinctions between them.

Modular construction offers numerous advantages, including reduced construction time, cost savings, and increased safety. As the industry continues to evolve and prioritize sustainable and efficient methods, I believe we will see an increase in the use of modular construction in the future.
