I’m planning a prefab home that starts life as a compact 2-bed, 2-bath unit and later grows into a full 4BHK by adding a first-floor module. The structure will rely on a mix of mild-steel framing and repurposed shipping containers, oriented to the east for optimal light and ventilation. My priorities are a clean modern look, an open-plan core, and generous natural light, so thoughtful window placement and voids matter just as much as the steel-to-container interface. Here’s what I need from you: • Concept drawings that show the initial 2BHK ground floor and the future first-floor expansion path. • Structural plans detailing how MS members connect to container modules for quick assembly/disassembly. • 3D visuals or walkthroughs that illustrate the modern aesthetic, open floor plan, and daylight strategy. • A concise assembly guide noting bolt locations, lifting points, and any specialised hardware. If you’ve tackled similar hybrid prefab projects, especially ones that break down for transport and re-erection, I’d love to see them. Let’s collaborate on a design that’s as flexible as it is stylish.
