New and existing private schools, charter schools, and public schools in areas such as Aberdeen, Gaithersburg, and Chestertown prefer modular classrooms & portable classrooms because they are delivered in a very short period of time and are ready for occupancy quickly. Maryland schools do not have a lot of down-time so construction speed is important. Other benefits of modular include affordable purchase options and flexible lease rates.
For D.C. schools, there has been a decade of continued enrollment growth by making investments into schools, their students, and educators. To keep up with this growth, modular classrooms have been a necessity for both public and charter schools.
