E-House Frequently Asked Questions
Here are some common questions we get about electrical houses and modular construction.
Q: What is an E-House used for?
E-houses (ehouses) are prefabricated modular buildings designed to house electrical systems—such as switchgear, transformers, and control panels—while protecting them from weather, impact, and environmental risks.
Q: How are E-Houses installed?
Units are fabricated off-site, delivered via truck, and set into place using forklifts or cranes. Most arrive pre-wired and ready for final hook-up.
Q: Can E-Houses be customized?
Yes. They can include HVAC, lighting, battery rooms, fire-rated walls, ballistic upgrades, and more, depending on your operational requirements.
Q: How long does it take to receive an E-House?
A: One of the biggest advantages of modular E-Houses is speed. While traditional stick-built electrical buildings can take several months to complete, WOI’s prefabricated E-Houses are typically ready within just a few weeks, depending on size and customization. Off-site fabrication keeps your project moving quickly and avoids typical delays that come with on-site construction.
Q: Do E-Houses offer cost savings compared to traditional construction?
A: Yes. While upfront costs are often similar, modular E-Houses deliver long-term savings by reducing installation time, minimizing site disruption, and avoiding downtime. Because they arrive prefabricated and ready to set in place, you also skip the added expenses of on-site labor, delays, and the mess that comes with stick-built construction.
