Customizable, Modular WorkSpaces - Grow with Your Business

Growing pains don’t always have to hurt. If your business is expanding and you need more space to house your people, inventory, and operations safely, we’ve got a pain-free, cost-effective, and fully customizable solution; inplant offices. Inplant offices are modular, pre-engineered buildings erected as independent workspaces. You can customize your modular office with a large variety of features and functions and still benefit from the pre-engineered design that allows for a fast, sturdy installation.

The modular design creates an enclosed work environment separate from the surrounding facility that is functional and yet fully portable if needed. Inplant offices are typically used as administrative offices to keep supervisors close to the plant floor to oversee daily operations and quickly respond when needed. Create your modular buildings to meet various functions aside from office space, including quality control, clean rooms, personnel break or locker areas, conference rooms, and more.

Inplant Offices Workspace Applications:

  • Laser rooms
  • Equipment enclosures
  • Environmental rooms
  • Security offices
  • Conference and meeting rooms
  • Storage rooms
  • Cafeterias

Customizable AND Economical Pre-Engineered Inplant Offices

It’s easy to make it your own when it comes to in-plant office space because the components are pre-engineered and designed to work together without the need for expensive, time-consuming planning, engineering, and installation. Steel or aluminum prefabricated panels fit together to build the structures. Depending on the dimensions and possible load-bearing capacity, the Apex team will guide you to the best structural design to satisfy your space goals.
