Modification pricing

Please note that the prices listed below refer exclusively to the cost of the building structure. This price includes only the structure in the specified technical options. The foundation, engineering and electrical systems, as well as the interior and exterior finishes, are not included in the structure price.

You can learn more about our building structure technology here.

For your convenience, we have developed four main technological solutions:

Basic

starting from 135€/m2

Our basic preset delivers a foundational solution for the building frame, giving you a prefabricated structure that you can then customize and complete.

It’s a great choice for those looking to reduce costs and who have the expertise to complete the construction themselves.

Optimal

starting from 225€/m2

The optimal preset is designed for moderate climates, with a building frame that includes 200 millimeters of insulation and an internal vapor barrier. This setup guarantees a comfortable microclimate and supports the structural integrity and longevity of the building.

This solution is perfect for comfortable year-round living in regions with mild winter conditions.

Passive

starting from 290€/m2

This preset features additional external insulation for the building frame, with thickness adjusted according to local climate conditions.

The primary benefit of this solution is enhanced thermal protection, resulting in a cooler home during the summer and reduced energy consumption for heating in the winter. Over the next decade, this passive insulation will lead to substantial savings on both heating and cooling costs.

This solution is well-suited for regions with harsh winters as well as very hot climates.

Super Passive

starting from 310€/m2

Our SuperPassive Preset meets Passivhaus standards, providing an exceptional solution for energy-efficient, comfortable homes. These prefab preset feature advanced insulation that maintains a steady internal temperature year-round, reducing energy use by up to 75% compared to standard builds.

That also prevents draughts, cold spots, mold, and condensation, promoting a healthier living environment. Designed with a ‘fabric first’ approach and backed by extensive research, our SuperPassive walls deliver lasting quality and performance for both comfort and sustainability.
