This is a detailed grand neoclassical mansion estate 3D model, designed with a symmetrical Beaux-Arts architectural language. The model features a luxurious central mansion, formal entrance portico, mansard-style roof, classical columns, ornate façade details, side colonnades, commercial-style side wings, and a large front courtyard with fountain plaza layout.

The building combines cream stone façades, dark roof volumes, tall arched windows, decorative cornices, balustrades, wall lanterns, and refined classical proportions. The overall layout creates a prestigious estate, luxury sales center, hotel entrance, wedding venue, private club, or high-end commercial reception scene.

The model is suitable for architectural visualization, real estate presentation, urban streetscape scenes, game environments, cinematic backgrounds, VR/AR projects, and luxury environment design.
