ZSJH Custom Modular Vacation Houses combine a steel structural system, insulated enclosure, panoramic glazing and optional finished interiors into a coordinated off-site building package. The product family supports compact cabins, space-capsule concepts, villas, reception buildings and multi-module resort units. Layout, façade, interior style and smart systems can be adapted to the site and operating model. One-storey, two-storey and engineered three-storey solutions are available; final dimensions and structural performance are determined by project loads, local approvals and transportation conditions.
