OTOgreen Wall — Rafa Ortega

OTOgreen Wall — Rafa Ortega

OTOgreen Wall integrates nature, well-being, and sound absorption into a single surface. Designed by Rafa Ortega for Greenarea, it transforms the wall into a vertical garden of high sensory value, where preserved vegetation and acoustic panels work together to create healthier, more balanced, and welcoming environments. Nature acts as an anchor to our emotional state.

The combination of natural surfaces and wall composition creates a more organic and relaxed perception of space, adding texture, depth, and a direct visual connection to nature. Its design allows for flexible configurations that can be integrated into different scales and architectural styles, transforming the wall into a living element within the interior design.

OTOgreen Wall enhances acoustic comfort while introducing a natural and contemporary aesthetic linked to environmental well-being. The combination of sound absorption, preserved vegetation, and sustainable materials makes it a particularly effective solution for offices, hospitality venues, corporate spaces, and collaborative environments where health, design, and spatial experience are essential components of interior architecture.
