The first Czech 3D-printed floating house Prvok od Buřinky (Protozoon by Buřinka) has been ‘built’ or rather ‘printed’ using concrete in České Budějovice in Czech Republic. Designed by artist Michal Trpák, and architects Jiří Vele and Kateřina Nováková in collaboration with various other consultants and collaborators, the house draws inspiration from the shape of microscopic animals called protozoa. The entire house, including the internal partitions, was 3D printed and built using 17 tons of concrete mixture in only 32 hours, and completed on June 29, 2020. The house has been built in České Budějovice, and as the concrete hardens in a span of 28 days, it will soon be transported to Prague. Upon completion, the house will be open to the public at Střelecký Island, on the Vltava river.

“About three years ago, when I designed a dental lab, which was an organic form, I started thinking about using the idea of 3D printing. Though it did not happen at the time, the idea of creating a 3D printed house stayed in my mind which I started to develop last year as a part of the art exhibition Art in the city in Ceske Budejovice in Czech Republic. After this 3D printing symposium, I started developing the idea with two other architects to create the 3D printed house Prvok (Protozoa),” informs Trpák.

The initial design approach was to create an organic shape, inspired by protozoa, with sculptural façade, curved lines and windows. The house was always conceptualised as a holiday home for countryside by the water. However, the façade and its relief structure changed and evolved over time. Progressively, the company that initiated the Prvok (Protozoon) has been undergoing important tests, such as the static pressure test, which concluded that the internal load-bearing wall can withstand 50-ton load, much more than any avalanche can throw at it. These mechanical and sustainable resistance tests were done in collaboration with the Experimental centre of the Faculty of Civil Engineering at the Czech Technical University in Prague to showcase the future of 3D printing in Czech Republic and the world.

“The most significant features of this 3D printed house are organic shapes in not only its walls but also windows, with no inner doors and three different spaces - bedroom, bathroom and living room. The house can be dismantled into these three spaces for transport and to assemble it on site. This creates an ease in processes as we are building this house in an old factory hall,” adds Trpák.

In the beginning of June, the building society Stavební spořitelna Česká spořitelna (Buřinka) conducted a survey that showed that the 3D-printing technology is being well received by the public. “More than a half of our clients can imagine living in a 3D-printed house, whether it is round or angular. Only one quarter of them do not see 3D-printing as a direction the Czech construction industry might take,” explains Libor Vošický, chairman of the Board of Directors of Stavební spořitelna.

The collaborators, artists, and architects involved believe this project will act as a game-changer in the 3D printing industry, and will help burst myths and make it a common practice. To make it a success, the industry needs cooperation from academics, further development of mixture composition, extended use of the robots for other construction purposes and the introduction of 3D printing to the common and professional public.

“In order for the 3D-printing technology to become part of the construction industry, we need to introduce it to researchers as well as architects, builders, government and other authorities. New study fields must be created,” says Jiří Vele, the architect participating in development of the control program for the 3D-printing robot at the Czech Technical University in Prague.  

From August 18, 2020, the house will be placed on Střelecký Island and made open to the public.
