Modern Geometric Architectural Concept Elevation

A sharp, sophisticated architectural pen and ink graphic illustration showcasing a modern minimalist concrete and glass cantilevered luxury residence. Set on a rocky coastal cliff side overlooking a calm sea, the building features bold geometric rectangular volumes, floor-to-ceiling glass walls, floating staircases, and an infinity pool projecting over the ocean. The rendering style emphasizes ultra-clean ruler-straight technical draft lines, minimal cross-hatching, and subtle dot-stippling gradients to represent glass transparency and concrete texture. Foreground features slender minimalist pine trees and sharp cliff rock textures rendered with precise contour lines. Light source is a high afternoon sun, casting sharp, crisp 45-degree geometric cast shadows across the clean white building surfaces. Tone is modern, luxurious, serene, precise, and sophisticated. Composition is a balanced two-point perspective exterior shot with generous negative sky space. Technical specs include 0.2mm drafting pen line precision, pristine black ink on smooth white Bristol board, architectural schematic blueprint clarity, modern brutalist design aesthetic.
