Key Architectural & Fabrication Systems

• Thermal & Acoustic Insulation:

  To prevent heat bridging through the steel envelope, walls and ceilings are fitted with closed-cell spray polyurethane foam (SPF), Rockwool batts (50–100 mm), or EPS sandwich panels, paired with a continuous thermal break barrier.

• Internal Structural Reinforcement:

  Cutting large openings for full-length windows, sliding patio doors, or joined container expanses requires welded structural steel tubing (RHS/SHS) or universal beams to preserve structural integrity.

• Interior Finishes:

  • Walls & Ceiling: Moisture-resistant gypsum drywall, pre-finished PVC sheets, or fiber cement boards (V-Board) with washable luxury emulsions.

  • Flooring: Heavy-duty water-resistant vinyl planks (SPC), laminated engineered wood, or vitrified tiles over high-density cement board subfloors.

• Plumbing & Sanitary:

  Compact, space-saving layouts with PEX water supply lines, sound-insulated PVC drainage pipes, integrated instant water heaters, concealed cisterns, and dry/wet segregated bathrooms.

• Electrical & Smart Home:

  Fire-retardant concealed conduit wiring, modular switchboards, dedicated MCB/ELCB distribution panels, energy-efficient recessed LED illumination, and split-AC pre-wiring.

• Exterior Cladding & Weatherproofing:

  Anti-corrosive zinc-phosphate primer topped with automotive-grade polyurethane (PU) paint, accented optionally with exterior WPC (wood-plastic composite) louvers, timber slat siding, or green living walls.
