In architectural projects developed on steep terrain, González & Jacobson architecture studio implements layered wall systems for the design and construction of stepped platforms.

Layered green walls are a solution used on sloping terrain to stabilize the ground while integrating vegetation into the retaining system itself. They are constructed using successive layers of compacted earth—called layers—reinforced with mesh, geotextiles, or structural systems that create safe and stable platforms.

The design of a layered green wall begins long before construction. It all starts with a topographic and geotechnical study, carried out by the González & Jacobson team of professionals, which is essential to understanding the slope, soil type, load-bearing capacity of the ground, and water behaviour. This information determines the height of the wall, the necessary retaining system, and the type of structural reinforcement. From there, the engineering project is developed, defining:

• The geometry of the platforms
• The slope and height of each layer
• The internal reinforcements (geogrids or geotextiles)
• The drainage systems
• The vegetation and landscaping finish

On-site, the process begins with excavation and site preparation. Then, the layers are laid in compacted sections, incorporating internal reinforcements that improve the wall’s resistance to earth pressure. Vegetation and drainage systems are placed on the exterior to control water and promote vegetation growth.

In addition to their structural function, these walls help reduce erosion, improve landscape integration, and soften the visual impact of steep slopes. Compared to traditional concrete walls, they offer a much more natural and sustainable look, especially in residential projects where the relationship between architecture and landscape is fundamental.

When well-designed, layered green walls transform a technical solution into an architectural element that provides aesthetic value, efficiency, and a connection with the surrounding environment.
