⭐ Exclusive advantages of our 37 m² Foldable House

Every detail has been designed to stand out from other solutions on the market. Here is why our FoldBox is superior:

🔩 Structure without welding points

🔧 Manufactured in a single piece, without visible welds, improving its strength, durability and structural finish.
💬 Most foldable houses include multiple weld points that weaken the structure over time.

🧱 Optimized interior height: 2.20 m

📏 Enjoy a more comfortable living space thanks to a minimum height of 2.20 metres.
💬 Standard models on the market are often limited to just 2 m, creating a feeling of confinement.

🧊 Roof with EPS composite panel

🧩 Aesthetic and functional panels with integrated thermal insulation.
💡 Also allows clean installation of recessed lighting.
💬 Other houses use visible metal sheets, requiring lighting reinstallation after assembly.

💡 Built-in LED lighting

🌟 Factory-installed directly into the ceiling.
💬 Avoids external, unattractive installations. Result: a more elegant home from day one.

🍽️ Fully equipped superior kitchen

🏅 Tall cabinets, authentic marble countertop and modern design.
💬 Other houses feature shorter units with less resistant artificial marble.

🎨 High-precision exterior finishes

🛠️ Claddings and assemblies carried out by qualified personnel, taking care of every detail.
💬 We guarantee a premium exterior look, exceeding the typical industrial finish of the sector.

🏗️ Additional structural reinforcement

📐 Internal structure with multiple welded square tubes for maximum stability.
💬 Although slightly heavier, it provides robustness not found in other similar houses.
