I need a clean, modern 3D concept that shows how a brand-new two-bedroom unit can fit within a house that already contains another two bedrooms. I’m only after the structural idea at this stage—no furniture, finishes, or décor—so the focus is on walls, openings, circulation, and how services could be routed. I’d like you to break free from the current layout and propose an entirely new arrangement that maximises space efficiency and flow. A single consolidated model plus a couple of high-resolution perspective views (and a simple floor-plan screenshot or export) will be enough for me to discuss feasibility with my builder. Feel free to use whatever tool suits you best—SketchUp, Revit, 3ds Max, Rhino—as long as the final files are shareable and I can review them in a common viewer or as PDFs. Turnaround within a week would be ideal, but let me know if you need a bit longer.
