Detached house in Vilamarxant, Valencia

A cistern roof is an innovation in the field of sustainable architecture and ecological design, particularly adapted to respond to the needs of dry climates such as the Mediterranean. In the case of the single-family house in Vilamarxant, the vegetation cover is designed with a rhizome system with succulent plants, which contributes to create a self-sufficient ecosystem that minimizes the need for external resources such as water for irrigation.
Crassic plants optimize the use of stored water. This type of plant is ideal for green roofs because their adaptability allows them to thrive in conditions of water scarcity.

The Vilamarxant cistern cover has a remarkable water storage capacity, reaching up to 18 liters per square meter. This storage volume is essential, as it provides an accessible water reserve for vegetation during the hottest and driest months of the year. This system not only reduces dependence on conventional irrigation, but also promotes a cooler microclimate around the house, improves air quality and increases local biodiversity.

In addition, this type of roof contributes to sustainable water management by capturing and storing rainwater that would otherwise be lost to runoff. This method is not only beneficial to the direct environment of the house, but also relieves pressure on municipal water management systems, thus contributing to a more holistic and sustainable management of natural resources in the area.
