Concrete House Doubles As Large-Scale Water Filtration System

The RainHouse is a building that collects run-off and filters it through the structure.


At the recent Milan Design Week, Budapest-based designer concrete firm IVANKA presented a demonstration model of its The Water of Life project which highlights an innovative rainwater management system.

The RAINHOUSE is a building that collects rain and turns it into high quality drinking water. The building is made with IVANKA’s bio-concrete, a material that has a PH neutral orientation and is bio-compatible with water. What makes the technology built into the RAINHOUSE different from other filtration technologies is that the system filters raw rain water physically and in a natural way, without the need for additional chemicals, to produce sun-distilled drinking water of the highest quality.

During the demonstration, rain was introduced into the system via a fake cloud mechanism that was suspended over the building. The rain fell onto the rooftop concrete and flowed to a storage tank that was lined with bio-concrete. Visitors to the RAINHOUSE were able to view the rain filtration process and taste the resulting distilled water.

As the population continues to grow, freshwater is also increasingly becoming a much needed resource, and in the future, it will even be more valuable than other resources. IVANKA’s The Water of Life project is dedicated to developing a sustainable source for freshwater.

Katalin and Andras Ivanka say,

Rain is the initial, the most important and purest, renewable source of the freshwater cycle – a much better choice than any other source such as lakes, rivers or mineral waters from underground. The technology we are working on represents a high ethical value as it turns rain into the highest quality drinking water in a pure and natural way of processing. It will provide access to affordable clean water for small and big scale users, from families to big companies, leaving the smallest possible ecological footprint in the process.

For six months, the firm tested the rain harvesting technology at Hungary’s Balaton Uplands National Park, whose location and conditions were favorable for the project. Lake Balaton is the largest freshwater surface in Europe and accounts for the pureness of the air and the favorably frequent rains in the area.

IVANKA’s rain harvesting system shows how homes and buildings could be built in the future and be their own water sources for its residents.
