The earlier you involve a visualizer, the better the final result will be, as it allows the visual narrative to evolve naturally alongside your architecture. However, if a deadline is tight, an experienced specialist can deliver high-quality renderings in a very short timeframe, provided the design team delivers clear project materials and a well-defined brief. Ultimately, the timeline depends heavily on how many rounds of iterations the client wants to make. If the concept is locked and decisions are made fast, a stunning result can be achieved even on the most compressed schedule.
