Cassone Prefab Building

You may have heard the terms prefab and modular thrown around in reference to construction projects and practices. However, you may not know exactly what those words mean, and how prefab construction is different from modular construction. While many people use the terms interchangeably and assume they are synonymous, they actually describe two specific types of construction.

If you’re in the market for space and don’t want to undertake traditional construction projects, both prefab and modular construction could provide solutions for your space needs. Each method has its strengths and weaknesses, but before leaping into the world of non-traditional buildings you should understand the differences between a modular building and a prefab building and what each has to offer. Keep reading if you’re considering a prefab or modular building in NYC to learn the differences between the two.

Prefab Buildings

Prefab, which is short for prefabricated, buildings are those buildings which have their components built under the controlled conditions of a factory. The components are not built on site, but are rather assembled remotely at a manufacturing facility, then trucked to the site of the building construction. There, they are assembled to create the designed structure. Because the structural components are created in a manufacturing facility, they can be assembled under controlled conditions without concern for weather and other factors that may slow traditional construction projects and drive costs higher. As a result, prefab construction offers an efficient building method that is both cost-effective and quick to erect. Some of the benefits of prefab construction include greater control over production variables, streamlines scheduling for construction, and fewer challenges logistically. Because all construction takes place in a factory setting, there is less material waste and increased opportunities for recycling. That makes prefab construction environmentally friendly. It’s also safer for construction workers than traditional building techniques because they are exposed to the weather and other jobsite dangers for less time. There are many types of structures that can be considered prefab. In fact, modular buildings are considered a form of prefab building, with the other being panelized buildings.

Modular Buildings

Modular buildings are a type of prefab building that takes the efficiencies created by prefab building techniques to the next level. Instead of simply creating building components that must be assembled into a structure on site, as is the case with panelization, modular building construction involves whole sections of the final structure that are manufactured off-site. Then, those prebuilt units are assembled together on the construction site into a building. It’s like assembling blocks, as modular building sections can be stacked or adjoined to create larger buildings. Modular buildings feature the shortest on-site build time of any prefab building method. Many prebuilt modular units come already fitted with plumbing and electrical systems intact. Some even go so far as to add interior design elements before the modular units are shipped out to the construction site, meaning building only must assemble the units to one another to create sprawling structures that would otherwise take much longer to build. Because of this high degree of efficiency and minimal time spent on-site, modular building cost is among the lowest in the construction industry when compared with other building types.​​​

Cassone Modular Buildings

If you’re in the market for additional space, consider prefab or modular buildings for your needs. Remember that all modular buildings are prefab buildings, but not all prefab buildings are modular. To learn more about the differences between prefab and modular buildings, visit Cassone Leasing at
