Style Transfer Tools for Architecture | RunDiffusion

Style transfer is a powerful way to present architectural concepts without relying on photorealism. By changing the visual style of a design into watercolor, ink, pencil, painting, or mixed treatments, architects can emphasize mood, storytelling, and creative direction while keeping geometry intact.
