Customer Feedback
In early 2024, a Spanish construction contracting company ordered six 40-foot expandable container houses from YG for an infrastructure project in the suburbs of Madrid. Since the workers’ dormitories needed to be constructed within two weeks, they chose our quickly deployable, ready-to-use housing.
Upon arrival, local workers completed the installation in just four days, and the units were immediately operational on-site. Customer feedback: “Compared to traditional brick-concrete structures, these expandable container houses not only save 40% in costs but can also be folded up and transported to the next construction site after the project is completed.”
This case study fully demonstrates the efficiency and practical value of the 40-foot expandable container house on European construction sites and has helped YG gain greater customer trust in the Spanish market.
