Modèle Architectural Isométrique Circulaire Étagé

An isometric architectural concept rendering of a [modern circular tiered building] on a square podium site, rendered in a minimalist white paper-model style. The main subject features 5 stacked circular tiers: a wide ground floor ring, three progressively smaller upper rings with continuous narrow vertical window slits, and a top circular roof disk featuring an off-center small rectangular rooftop volume and a subtle wedge-shaped notch on the rim. Two simple rectilinear annexes attach to the building: a low rectangular wing extending toward the front right and a tall plain rectangular tower block at the rear right. A separate small circular pavilion stands near the front left, linked by a short pedestrian walkway. The square site has rounded corners, pale gray paved paths, and muted sage green lawns with 9 stylized minimalist trees and shrubs distributed across the perimeter and islands. Orthographic isometric camera angle looking down, centered composition with abundant negative space on a clean off-white background. Crisp ambient occlusion, delicate technical linework, soft diffused shadows, clean geometric massing. No people, no vehicles, no signage, no text.
