House 4, on a narrow plot in Cluj-Napoca, bridges industrial and residential zones. Extended and restructured, it features a minimalist, industrial design with metal cladding and large windows that fill the interior with light. Despite its size, the home offers generous, open spaces across three levels, blending concrete, wood, and natural textures. Designed by and for architects, it maximizes space, comfort, and innovation, becoming both a family home and architectural statement.
