Wall Garden

In recent years there has been an increasing need for nature inclusive solutions in the construction sector. The practice asks for new solutions contributing to the development of sustainable, resilient and liveable cities. Under the guidance of the Dutch government, greening of the cities has become one of the aims of municipalities in the Netherlands and the focus of some emerging companies and design offices. In cities, quay masonry walls, thanks to their close contact with water, have the potential to be ecologically engineered to favour vegetation, thereby contributing to the renaturing of urban areas. By building a prototype of an innovative masonry building system, this project aims to investigate the potential for improving the integration between masonry quay walls and vegetation. The set-up consists of a dry-stacking system for brick masonry: strong polyamide elements interconnect the bricks, providing strength to the masonry without the need for mortar. The space in between bricks, traditionally filled with mortar, is to be filled with compost material, providing an ideal substrate for plant growth and a buffer for water storage (figure 1). In addition to improved integration between masonry walls and vegetation, the proposed dry-stacking system allows for easy reuse of bricks, thereby contributing to circularity and sustainability of the building industry. The project broadens and strengthens the national network in the field of urban ecology by bringing together expertise from the fields of architecture, ecology and the construction sector, from both academia and practice.
