Benefits of Modular Office Complex Construction

Compare the benefits of Modular Buildings over traditional construction.

Benefits-of-modular

Prefab offices come with many benefits. For one, their time to completion is faster than traditional construction. This allows you to get the space you need in a quick manner, without the hassle. And because they are built in factories, there is less site disturbance to your location. 

Another significant benefit of modular office complexes is that they're more affordable than site-built construction. If you are looking for a fast and affordable space solution, modular construction may be right for you.   

Building Materials

Building Materials

Modular offices are built with:

  • Solid wood framing
  • Steel exterior walls and durable rubber roofing
  • Vinyl-covered gypsum and vinyl composite flooring inside

These office modular systems are fully equipped with electric and plumbing, energy-efficient lighting, and are HVAC controlled with programmable thermostats for comfort.

Case Study

Delaware River Stevedores

Recognizing that they would be better off handling all terminal administrative activities from one building, Delaware River Stevedores (DRS) decided to pursue placing a large modular building at the marine terminal. BOXX Modular recently completed their brand new 7,500+ square foot modular office building which allows DRS to consolidate their office space into one structure.

Turnkey Solutions

A turn-key construction project, from floor plan layout to exterior paint colors, this building was custom built to exactly meet DRS’s specifications.

Benefits of Modular

When commercial & industrial companies are looking for durable office space in a short time-frame, modular office buildings are a great solution.

Code Compliant

The project included code compliant decks, steps, and ramps. Site constructed awnings were included to protect visitors and occupants from the weather. 

7,500 sq. ft.

DRS is now able to have their administrative staff all under one roof so that they can more effectively carry out their daily operational responsibilities.
