Rainwater Collection: The Latest Architecture and News

In an open competition, ICON’s Initiative 99 requested participants to design a home using ICON’s 3D printing technologies while keeping the construction budget under $99,000. Among the three selected winners for the Open Category, New Zealand-based office MTspace Studio proposes a robust flood-resistant design, in response to the housing crisis in New Zealand’s flood zones. Titled “Wai Home” after the Māori word for water, the concept revolves around the idea of working with this essential natural element. The design features innovative rainwater collection and storage systems, along with elements to increase the resilience of the construction in the face of increasing threats.

An arid environment refers to specific regions characterized by a severe lack of available water and extremely dry weather conditions. More specifically, arid regions by definition, receive less than 25 centimeters of rain per year. In the immense vastness of arid environments, where extreme climates present significant challenges, the role of water in architecture takes on a new dimension.

For centuries, architects and designers dealing with harsh desert landscapes and the vital necessity of water have invented techniques, technologies, and new structures. Moreover, many creative approaches have been created to harness, collect, and cool water in arid environments.

The climate crisis has accentuated changes in the amount of rainfall, causing droughts or storms with large volumes of water, which result in floods that can cause great damage to urban infrastructure. To combat this, the sponge city is a solution that has a green infrastructure to operate the infiltration, absorption, storage and even purification of these surface waters.

The Climate Tile is a pilot project designed to catch and redirect 30% of the projected extra rainwater coming due to climate change. Created by THIRD NATURE with IBF and ACO Nordic, the project will be inaugurated on a 50m pavement stretch at Nørrebro in Copenhagen. The first sidewalk was created as an innovative climate project that utilizes the Climate Tile to create a beautiful and adaptable cityscape. Aimed at densely populated cities, the tile handles water through a technical system that treats water as a valuable resource.

For the "Imagine Angers" international design competition, Vincent Callebaut Architectures worked in collaboration with Bouygues Immobilier group to submit a proposal for the French city at the intersection of social and technological innovation, with a focus on ecology and hospitality. Named Arboricole, meaning “tree” and “cultivation,” this live-work-play environment gives back as much to the environment as it does its users. Although WY-TO prevailed in the competition, the Callebaut scheme succeeded in winning the public vote.

Few sounds in this world are quite as satisfying as that of fresh rainwater falling on a tin roof. However, this soothing sensation is just one element of the Cloud House, a unique, interactive rainwater-harvesting system created by designer Matthew Mazzotta in Springfield, Missouri. From the comfort of a wooden rocking chair, the user is immersed in a rural farm experience, offering passers-by a moment to slow down, enjoy fresh edible plants and, as promised, bask in the sound of rain striking a tin roof.

KAMJZ have unveiled their proposal for the UIA’s MOLEWA (Mount Lu Estate of World Architecture) competition, which tasked participants with designing several cultural and commercial complexes near one of the world’s largest flower theme parks in Ruichang, China. Titled Ruichang Flower Market, KAMJZ's design contemplates a series of shopping streets with high-end, as well as more vernacular shopping spaces, in particular a specialty area carrying flowers grown in the neighboring Flower Theme Park, traditional crafts, and souvenirs.

In many African countries, clean water is still a luxury. Wars are fought over it, families are uprooted for it, and entire communities perish without it. The scarcity of freshwater has plagued nations in Africa and around the world for centuries. Now, non-profit group PITCHAfrica is fixing the problem with a novel combination of sport and design. Part of a 10-acre Waterbank Campus comprised of 7 water-harvesting buildings, the soccer (or “futsal”) stadium is capable of hosting up to 1500 people, helping to save, educate and unite communities that are most in need.
