In Niederanven, Luxembourg, ODA Architects built the country’s first 3D printed residential project. The 47 m² Tiny House acts as a prototype for fast, low-emission and circular construction. Its approach offers useful insights for architects, interior designers, landscape designers and product designers who work with sustainable materials and modular building systems.

Compact Layout with a Clear Spatial Flow

The Tiny House sits on a narrow footprint: 3.5 metres wide and more than 17 metres long. The entrance lies on the south side, where it also connects to a terrace. Large openings on both façades bring daylight deep into the interior.

Inside, the layout focuses on clarity and comfort. A central hall links the entrance to a bathroom and a built-in technical zone, then leads to the bedroom at the far end. To the left, the living area combines the kitchen, dining space and lounge. This creates an open and social heart for the home. Windows frame views towards green spaces on the north and northeast sides, strengthening the connection with the landscape.

3D Printing as a Low-Waste Building Method

3D printing forms the core of the project’s innovation. The printed walls receive an eco-friendly insulation fill. This method reduces material waste and lowers emissions compared to traditional building techniques.

Speed adds another advantage. The printing phase is expected to take about one week. The complete build, including finishing, should take around four weeks. This makes the system attractive for fast, low-impact housing.

Modular Elements Enable Circular Use

The Tiny House uses a modular approach. Each printed element can be assembled, taken apart and reused. This flexibility allows the building to move or adapt over time. It also prevents demolition waste and supports circular construction.

By treating each component as a reusable part, the design becomes an example of how digital fabrication can extend a building’s life cycle. It also shows how modularity can support changing needs and locations.

Energy Systems that Support Autonomy

Solar panels on the roof power the home. They generate electricity for daily use and for the underfloor heating system, which runs on energy-efficient heating film. These systems increase the building’s independence and help reduce operational emissions.

A Step Forward for 3D Printed Housing

ODA Architects aims to show how 3D printing can support sustainable, adaptable and affordable living. The Tiny House acts as both a residence and a test case for future circular and digitally produced buildings. It opens new possibilities for designers who explore material innovation, biobased insulation and modular construction systems.
