Rotterdam-based David Moreno (previously) prefers his spatial pieces to oscillate between initial sketches of architectural projects and fully-realized constructions. His steel sculptures are comprised of lengthy metal strips and piano strings that are arranged to form building complexes, cathedrals, and steep flights of stairs. Despite being three-dimensional artworks, they mimic an architect’s outlines with their swooping lines and grid-like qualities.

Moreno shares a plethora of his imaginative projects on Behance, in addition to some progress shots on his Instagram.
