I need a clean Revit model of a two-storey business center on a metal frame, building area no more than 1,000 m². The brief is deliberately simple: a clear rectangular mass, traditional exterior detailing, and only basic-shape furniture so the file stays light and easy to edit. Inside, lay out offices, meeting rooms, and shared common areas across the two levels. An underground bomb shelter must sit beneath the main footprint; keep its geometry minimal yet unmistakable. Structural steel elements should be native Revit families so later engineering checks run smoothly. Deliverables • Revit (.rvt) file that opens in 2026 Acceptance Criteria • Gross area ≤ 1,000 m², exactly two above-ground floors • Traditional façade; metal frame modeled accurately but without fabrication detail • Offices, meeting rooms, and common areas clearly labeled • Bomb shelter on its own underground level • Furniture kept to simple placeholder forms; no high-poly assets • File free of unused families, views, and warnings This is needed by tomorrow morning, the sooner the better, as primitive and simple as possible
