Modular Buildings for Every Industry

Modular School Buildings

California school districts are continuing to see a decline in enrollment, which means the state will distribute less funding for staff and school buildings. For schools that are currently in poor conditions and want to rebuild, this is a huge barrier. Modular buildings offer a smarter way to utilize limited funding, ensuring that students and staff are not relegated to use old, worn-out facilities.

At VESTA Modular, we provide new, custom school buildings as well as refurbished multi-classroom configurations. Interested in an entire modular school complete with bathrooms and hallways? We can do that, too. Our turnkey modular services can make the process of creating a new, clean classroom space even more efficient—order your desks, tables, chairs, and teachers’ lounge coffee equipment so your school is truly all ready to go.

Portable Classroom Trailers

While California school enrollment has been on the decline since the COVID pandemic, that can change at any time. Our temporary portable classrooms can be quickly deployed to aid in an influx of students.

Is your private or charter school undergoing a long-awaited renovation? A portable classroom is a cost-effective temporary solution during traditional building construction. VESTA’s competitive pricing and flexible financing terms offer a high-quality space solution for schools, whether they are looking to purchase or lease.
