Modern Concrete Tower in a Quiet Neighborhood

ChatGPT Prompt

A vertical brutalist single-family house rising as a narrow concrete tower at the end of a suburban cul-de-sac, clad in dark gray board-formed concrete with thin vertical slit windows running up its full height. The windows are cut so deep into the wall that they appear as dark lines rather than openings, and the low winter sun rakes across the surface to reveal every ridge and hollow of the formwork. A single storey-high entrance notch is set into the base, its interior lost in shadow. Bare asphalt curves around the plot, and a low concrete retaining wall marks the boundary against the street. The sky is a cold pale blue, the air still, the mood detached and uninviting, no people anywhere in the frame, professional architectural photography.
