Belgium-based provincial Centre for Sustainability and Innovation in construction, Kamp C, recently used Europe’s largest 3D concrete printer to complete an impressive accomplishment. The company created the world’s first two-story house to be 3D-printed in one piece, a 90-square meter dwelling measuring eight meters tall (the average size of terraced houses in the region).
“What makes this house so unique, is that we printed it with a fixed 3D concrete printer,” Emiel Ascione, the project manager at Kamp C, said in a press release. “Other houses that were printed around the world only have one floor. In many cases, the components were printed in a factory and were assembled on-site. We, however, printed the entire building envelope in one piece on-site.”
The project’s goal is to raise interest in 3D concrete printing as a building technique in the Belgian construction industry. The industry, like many others, continues to face environmental challenges from material and energy consumption, producing the need for reduced CO2 emissions and waste streams despite the growing demand for high-quality, affordable housing. This first house serves as a test that researchers will monitor for solidity over time. In the future, the company hopes to get printing time down from three weeks to just under two days.
Kamp C’s printed home is three times sturdier than those built with conventional quick build bricks, according to the company’s project manager. The printing technology saved an estimated 60% on material, time and budget, requiring less wire-mesh reinforcement than similar projects. Highlighting the principle of circular architecture, the design accommodates multipurpose options from use as a house, meeting space, office or exhibition space.
The model home includes an overhang with heavily curved walls and features low-energy capabilities with floor and ceiling heating, solar panels in the facade and a heat pump. Future designs will include a green roof.
