Completed in 2023, the project spans a total area of 13,267 square meters. This apartment complex serves as a primary example of modern urban housing design, reflecting the collaborative efforts of architectural firms MARMOLBRAVO and MADhel in the capital. ## Architectural Collaboration Details The project was led by a team of architects including Marina del Mármol, Mauro Bravo, Miguel Herraíz, and Daniel Bergman. Beyond the lead architects, the development involved Michael Becker as a collaborator architect. Technical oversight was provided by Germán Gómez, ensuring the structural integrity of the residential complex throughout the construction phase. ## Engineering and Technical Execution Structural engineering for the SFJ6 building was handled by Mecanismo, while the MEP systems were designed by Eadat. Alfonso Sáenz was responsible for the measurements, ensuring precise execution of the architectural plans. These specialized roles highlight the complex coordination required to deliver a large-scale residential project within the dense urban environment. ## Material Selection and Manufacturers The construction utilized specific products from manufacturers including Parklex Prodema, Technal, and Baumit. These materials were selected to meet the project's design and sustainability requirements. The integration of these specific brands demonstrates the technical standards applied to the building's facade and structural components, contributing to the overall aesthetic and functional quality. ## Visual Documentation and Photography The photographic documentation of the SFJ6 building was captured by Jose Hevia, providing a visual record of the completed structure. These images highlight the elevation and spatial organization of the apartments. The visual archive serves as a reference for the project's architectural language and its physical presence within the Madrid cityscape. ## Urban Context and Housing Situated in Madrid, the SFJ6 building addresses the demand for high-density residential housing. The project is categorized as an apartment complex, focusing on maximizing the utility of the 13,267 square meter footprint. This development aligns with contemporary urban planning trends in Spain, emphasizing efficient land use and modern residential living standards. ## Project Timeline and Publication The construction of the SFJ6 building concluded in 2023, marking a milestone for the involved architectural offices. The project was officially documented and published on November 3, 2026. This timeline reflects the period between the physical completion of the structure and its subsequent recognition within professional architectural media platforms and industry databases. ## Significance of Collaborative Design The SFJ6 building underscores the effectiveness of multi-firm collaboration in large-scale residential architecture. By integrating structural engineering, MEP expertise, and specialized material suppliers, the project achieves a cohesive design outcome. This development serves as a benchmark for future housing projects in Madrid, demonstrating the importance of interdisciplinary coordination in construction. ## Sources covering this story - https://www.archdaily.com/1010105/sfj6-building-marmolbravo-plus-madhel — --- _Summary written by Brifing from the original reporting.
