Architectural section cut diagram of a 4-story parametric residential building with spiral staircases, intricate interior spaces, and spacious balconies, all designed to evoke coastal identity. The diagram is presented on a black background in the style of Zaha Hadid, featuring smooth, flowing forms and bold lines. Include detailed notes on the side in white ink that read: "Murti," "Laycrypto," and "S brainfodr vRoyal Extracts." The building's facade integrates a steel mesh, while an intricately designed metal net drapes elegantly over the entire structure. Each floor should display small unique details, such as furniture arrangements or wall configurations, without repeated elements or unnecessary characters. Ensure the design conveys a sense of fluidity, sophistication, and connection with its surroundings.
