The three-room single-floor house is spread over 1,000 sq ft
and has a wooden terrace. Shaped like a boulder, it is surrounded by greenery
and open spaces all around. Four more houses are to be studied under the
Milestone Project at the site being developed as a “sculpture garden”.
According to information available on the project’s website,
these houses are intended to be occupied for at least several decades. The
builders say that 3D printing technology gives them freedom, while the
traditional concrete design was too rigid. They say that one of the advantages
of using a 3D concrete printer is that it has the ability to lay concrete only
where it is needed, thereby reducing wastage and CO2 emissions by using more
cement.
3D concrete printing also allows builders to design very fine
concrete structures. Another advantage of this technique is that builders can
fulfill the individual wishes of customers without increasing the cost of
construction. For this project, the builders said, 3D technology helped them
blend homes with naturally wooded surroundings as if they have always been in
this wood oasis.
The building elements of the first house were printed at
Eindhoven University of Technology, but the fifth house, a two-story building,
will be printed on site.
A few days ago, India also got its first 3D-printed house in
Chennai. The single storey house is 600 sq ft and was constructed using
indigenous concrete 3D printing technology.
The homebuilding team said that they had printed the
structure using a special concrete that they had developed to print large-scale
3D structures. He said the mixture was based on ordinary Portland cement, which
has a low water-cement ratio. The use of such local materials will reduce the
need for solid long-distance transportation to minimize environmental impact.
