This is a highly detailed, hand-drawn concept sketch in the style of a blueprint of an industrial design drawing, depicting a surrealistic vision of a building of the future 10-15 years from now, similar to Hayao Miyazaki's Howl's Moving Castle. The composition is visually striking, outlined in black ink on clean white sketch paper and colored in graphite. The building has multiple residential functions, living and recreational functions, as well as a certain push-fly mobile propulsion system for easy levitation.
