Facsa, a company specialized in integrated water cycle management, has inaugurated its new corporate headquarters in Castellón, Spain. Designed by Ramón Pascual’s architecture studio and built by Gimecons, the complex places a focus on functionality, sustainability and cutting-edge design. The interior architecture design was developed by Summumstudio, creating a space conceived to inspire the team while reflecting the company’s values.
With a built area of 8,600 square meters on a 17,000-square-meter plot, the headquarters integrates offices, workshops, warehouses and 2,500 square meters of green areas. The interior layout includes a spacious welcome hall on the ground floor, technical offices on the first floor and executive areas on the second floor. The challenge posed to the design team was to create an integrated concept that would merge architecture and branding to deliver a strong, coherent, corporate identity.
The main hall was conceived with a specific function -- to blur the boundary between “exterior and interior,” becoming a unifying nexus that integrates with the facade while establishing an architectural code that would serve as the basis for resolving the building’s remaining spaces.
The space symbolizes the integrated water cycle through a large metallic sculpture functioning as a staircase. This structure is enveloped by a curtain of water cascading into a pond, creating an architectural landscape with strong symbolic value. Its design provides the complex with verticality, establishing an organizing axis that structures the rest of the project’s spaces under a rigorous order.
The interior design is articulated around this large central core, which vertically connects the spaces via the sculptural staircase. Resting on an expansive sheet of water, the staircase is framed within a triple-height courtyard, visually and functionally linking the three floors. The concept follows a minimalist and rational architectural language aligned with the image Facsa aims to project: simplicity, timelessness and coherence.
The design team focused on resolving key areas distributed across the three floors, forming the core of the facility. These areas include:
• Main hall and reception on the ground floor
• Reception and distribution on the second and third floors
• Presidency and executive offices
• Boardroom
Materials and Color Palette
When selecting material, the design team sought ones that would ensure coherence between the building’s interior and exterior design. Materials include high-quality porcelain tiles from Tau Ceramic Tiles, black iron, dark-toned lacquered aluminum and dark smoked glass to provide visual continuity.
The color palette remains within neutral tones that complement Facsa’s corporate identity. This selection generates a harmonious dialogue between the interior and exterior architecture, ensuring the building’s overall design is perceived as a coherent and unified extension. The interior design developed by Summumstudio for Facsa’s headquarters is a manifestation of functionality and innovation. Through its central core and the integration of water as a conceptual element, the project reflects the company’s essence and values, providing an inspiring workspace aligned with its identity.
