The cost of a building’s 3D model for illustrators varies by complexity, detail, and project scope—simple residential models start at $50–$200, while detailed commercial or historical structures can reach $500 to over $5,000. Custom models: Pricing rises with interior details, realistic texturing, or architectural accuracy—for example, a high-rise with accurate materials might cost $1,000–$5,000. Pre-made models: Budget-friendly for beginners, available on Sketchfab or Blender Market for $10–$100, avoiding custom creation costs. Overall, choose custom for specificity (higher cost) or pre-made for budget (lower cost).
