Common Questions About Indoff's Modular Buildings

What's the main advantage of using an Indoff Partner for a modular building project?

Your Indoff Partner serves as your single, expert point of contact from concept through completion. Instead of you having to manage architects, multiple manufacturers, and installers, your Partner leverages their decades of experience to listen to your goals, design a custom solution, and manage every detail of the project for you.

Do I need to find my own contractor for installation?

Not at all. Indoff is a full-service partner, which means we manage the entire project for you, including professional installation. Your Indoff Partner coordinates all the logistics to ensure your new modular building is assembled correctly and with minimal disruption to your daily operations.

Do your modular buildings include electrical and HVAC?

Yes, we provide fully functional, move-in-ready spaces. Our solutions can include a complete electrical kit with lighting and outlets, as well as integrated heating and air conditioning (HVAC) systems to create a comfortable, climate-controlled environment. Your Partner will incorporate all necessary utilities into the final design.

How long does installation take?

Significantly less time than traditional construction. Many standard in-plant offices can be installed in just a few days, minimizing disruption to your operations.

Are your modular buildings customizable?

Absolutely. Everything from the wall panels, doors, windows, and flooring to the electrical and HVAC systems can be customized to your exact specifications.

Can I move or expand the building later?

Yes. One of the greatest benefits of modular construction is its flexibility. The non-progressive design allows panels to be removed, replaced, or relocated easily to accommodate future growth.
