After years of research, HOLEDECK has developed the concrete structure most sustainable in the world: The H-ONE. This innovative solution allows to reduce more than 50% of carbon emissions of the structure of a building, also generating significant cost savings.

HOLEDECK optimizes every aspect of structural design to improve performance and sustainability:
1 Optimal thickness against fire
2 Optimal slab between ribs
3 Optimal volume in the nerves
4 Possibility of further optimizing the structure when post-editing
HOLEDECK reduces approximately 40% of the total CO2 emissions in the construction of your building.


HOLEDECK reduces more than 50% of concrete and steel, reducing the total weight of the structure and proportionally reducing the costs and carbon emissions.

The system is versatile and adaptable, suitable for both conventional and residential homes large span projects. Allows you to build slabs with spans between 6 and 22 metersOffering maximum flexibility in architectural design.

Outstanding works with different HOLEDECK systems. The flexibility and versatility of the products make them ideal for any reinforced concrete structure.

Throughout its history, HOLEDECK has received numerous awards that position its system among the best solutions on the market for concrete structures.









''HOLEDECK, an avant-garde structural system that enables spacious, column-free interiors while significantly reducing the building's carbon footprint by 50%''
"HOLEDECK is a simple and elegant way of creating coffer slabs, with holes in the webs. It overcomes one of the main obstacles to the use of coffer slabs, which is that all services usually have to run below the slab rather than in it. (...) Some of the best innovations come from simple ideas and HOLEDECK could re-energize this form of construction"
"Probably the most sustainable concrete structure in the world"
"(…) The HOLEDECK brings together in a simple formwork system, sustainability, material savings and structural efficiency demanded by society. Facing the new paradigm: making the planet a better place; HOLEDECK cooperates making lightweight and activable structures."
"(…) Its operating principle is the one desired by most structural teams: Maximizing structural inertia by keeping installation systems within the structural system by piercing the structural nerves where material is least needed."
"HOLEDECK is an outstanding structural solution for concrete slabs, technically efficient and flexible, and architecturally singular and attractive."
