3D printed tiny house uses solar panels for low-energy use
The Tiny House project in the commune of Niederanven marks the first use of 3D printing for a full residential structure in Luxembourg. Designed by ODA Architects in collaboration with Coral Construction Technologies, the structure covers 47 square meters of usable space, with each printing phase lasting less than 28 hours. The main purpose of the project is to test how 3D printing can produce housing in a faster and more affordable way in hopes of relieving the housing crisis that the country has been confronting.
The 3D printed Tiny House also shows how a structure can work with low energy use by installing solar panels on the roof to power up the home. The electricity also supplies energy to the film-based heating system under the floor, eliminating the need for water pipes or radiators. The architect’s goal is to keep the house simple to run and maintain, and in fact, the team has filled the walls with insulation made with low-impact materials after printing to reduce the energy use in the long term.

Green areas surround the cement structure
Going through the design of the 3D printed Tiny House, the interior has clear zones for different activities. When a person enters the house from the south side, they arrive in a small entrance hall, where a corridor starts. It connects the entrance with all the main rooms, which leads to the bathroom, a technical area, and at the end, the bedroom. To the left of the entrance is the living space combined with the kitchen and dining room in one continuous area.
This construction also has a door that opens to the terrace on the south side to give access to the outdoor space and connects the interior to the surrounding open areas. A main design idea is to connect the 3D printed Tiny House by ODA Architects with nature around it. The entrance in the center of the south wall gives quick access to the garden, and the structure has openings that face the north and northeast green areas to fulfill this design vision.

prototype can show potential affordable housing in europe
The company Coral Construction Technologies says that the project shows how 3D printing is used to build residences in a market with high housing costs. It adds that Luxembourg requires around 7,000 new apartments per year, but current output delivers under 4,000, and this gap produces high prices and long development timelines. A small 47 m² apartment in Luxembourg City costs more than EUR 560,000, but the 3D printed Tiny House runs an estimated cost of about one-third less and can be placed on sites not suitable for larger construction.
The construction reduces the need for manual labor, but on the upside, there’s less use of heavy machinery and decreased waste because the printer follows exact digital instructions. The municipality of Niederanven integrates the 3D printed Tiny House into the Hei wunne bleiwen program, which aims to provide starter housing for young residents who take part in community programs. The house is expected to be rented to its first tenant for a ten-year lease, and in addition, the project includes a plan to plant 21 trees to offset emissions from the production process. So far, the current structure stands as a prototype, with the goal to use it to inform future decisions about whether this method can support larger programs for affordable housing in Luxembourg and other European countries.
