A Modular Building IS:

  • A pre-manufactured portable building – Also known as a modular office space or prefab office. They often look similar to a permanent building, but the construction process is different. Modular buildings are manufactured in a controlled factory environment where each individual component is mass-produced on a production line. Modular units work a lot like a set of Legos. They are packaged as a set of individual parts with instructions for assembly. Each component fits together like a puzzle piece, making construction time quick and simple. not: Why Modular Construction is Faster.
  • A multi-unit office building – A modular building can have multiple rooms, adjoining units, or multiple levels (stackable). They are made of more permanent building materials such as steel, brick and hardwood.
  • Designed for long-term use – They address long-term needs (3+ years) and in some cases transition to permanent use.
  • Customizable – Similar to traditional construction, modular buildings, have almost endless design options and configurations.

A Modular Building IS NOT:

Not a storage container or mobile office

  • A mobile office trailer – Many people confuse modular buildings with mobile offices (and understandably so, as these terms are often used interchangeably). The difference: a mobile office is a one-unit temporary office space that sits on a wheel-and-chassis trailer base. They are generally made of wooden siding, vinyl flooring, and metal roofing.

  • A cheap alternative to traditional construction – Some modular designs can cost as much or even MORE than traditional construction. Your total cost will be affected by intricacy of the floor plan you choose, the type of building materials you request, and the labor required for assembly. If you are looking to save money with a modular build: KEEP IT SIMPLE. The more simple the floor plan, the quicker your building will be up and running, reducing your overall cost.
  • A shipping container complex – Re-purposed shipping containers (also known as ISO containers or storage units) have become a popular raw building material for apartment complexes, shopping centers, and restaurants/bars. They are NOT modular buildings. The difference: shipping containers are made of Cor-Ten steel and come in pre-configured sizes (20-or 40-feet long, 8 feet high). Their size limits design options.
