Architecture, Building and Structure Design Bradco Factory by Cristina Vaz Santos e Paulo Rodrigues Bradco is an industrial building designed for the production of watch straps and luxury leather goods in Castelo de Paiva, Portugal. The factory is planned around natural light. Several skylights were placed on the roof so that the production area stays bright for the employees. Stone from the region was used on the exterior, together with glass and steel, to link the building to its territory. Large glazed areas create transparency between the interior and the surrounding landscape. The project was carried out between 2019 and 2020.
