Key Questions to Ask Before Buying an Expandable Modular House

With the growing market for modular housing, expandable modular houses have become increasingly popular due to their flexibility, convenience, and cost-effectiveness. However, before making a purchase, it’s essential to ask the right questions to ensure you select the best product and avoid potential issues later.

1. What Are the Main Materials and Structure of the House?

Different manufacturers use various materials, such as steel structures, aluminum alloys, and sandwich panels. Ask about the main framework and wall materials to ensure the house meets your durability, insulation, and soundproofing needs.

Different regions have different regulations for temporary and movable housing. Before purchasing, consult with local authorities or suppliers to ensure the house design complies with relevant building codes to avoid legal or approval issues.
