A simple, easy-to-draw architectural concept sketch of a building that combines three styles: modern minimalist architecture with clean rectangular blocks and horizontal windows (inspired by Ludwig Mies van der Rohe), subtle Art Nouveau elements like a few tall central windows with gentle rounded tops and light decorative lines (inspired by Victor Horta), and a slight vertical twist made of stacked rectangular volumes rotated a few degrees (inspired by Santiago Calatrava). The building should be simple, clear, and sketch-like, with flat colors, clean outlines, minimal details, white and light gray tones, and a plain background, suitable as a reference for drawing by hand.
