What Holedeck does

Holedeck (legal entity SUSTAINABLE BUILDING S.L.) is a Madrid-headquartered construction technology company founded in 2012 that designs, patents, and licenses a perforated structural concrete slab system. Its core product family — H-ONE (unidirectional ribbed slab, 30/45/68 cm depths), HO-45 (bidirectional aligerado), H-FLAT (non-perforated variant), HOLEDECK Active (thermally activated slab), HOLEDECK CUSTOMIZE, and the Plugdeck modular installation system — integrates HVAC, electrical, plumbing, and data routing directly within the structural beam via engineered perforations, eliminating the need for separate suspended-ceiling or underfloor service zones. Molds are injection-molded in the EU from recycled ABS and polypropylene, and the underlying technology is protected by a worldwide patent. The company reports claimed material reductions of approximately 60% in concrete and 46% in steel versus conventional slabs, with associated embodied CO2 reductions of 40-55% and construction cost savings of up to 20%, plus a structural efficiency that allows roughly one additional floor for every five built.

Revenue is generated through three channels: hardware sales of reusable, container-shipped molds; project-based technical engineering services including feasibility studies, structural calculation, and HOLEDECK Zero embodied-carbon optimization consulting; and distributor or partner licensing. Go-to-market is specification-driven — Holedeck operates a globally certified structural engineering network that recommends the system to developers and contractors, supported by direct mold shipments and international distributor relationships. Confirmed project geographies include Spain, Andorra, Germany, the United States, Angola, and Paraguay, with applications spanning commercial, residential, industrial, hospitality, prefabricated construction, and building rehabilitation.

The customer base includes commercial real estate developers (Colonial, Conren Tramway), corporate end-users (MANGO headquarters, Logytel I+D), residential developers (Urbania, EMX Housing), constructors (ASAVA), and hospitality venues (Water Tower Restaurant, Heidelberg). The company has secured industry recognition including the CTBUH Performance and Innovation Award (2015), Best Tall Building Innovation Award (2015), and Premio Emprendedores Everis (2014). Strategic alliances include LafargeHolcim for integrated construction solutions and Uponor for thermally activated slab technology, with research collaborations including the Eduardo Torroja Institute (CSIC) and IECA. Headcount is 11-50 employees, financial figures are not publicly disclosed, and the company has received Spanish public R&D grants from CDTI and ENISA.

Revenue model

1. Mold Sales and Technical Assistance: Holedeck manufactures and sells reusable formwork molds (in ABS and polypropylene) for on-site fabrication of ribbed concrete slabs. The company supplies molds and provides technical assistance for in-situ fabrication. Pricing per square meter varies by project complexity, with a preliminary feasibility study conducted before quotation. molds are reusable across multiple projects, and distributors acquire materials directly under quality control frameworks.
2. Technical Engineering Services: Technical department conducts preliminary feasibility studies upon receiving project plans (DWG format). Offers structural calculation services, assembly training, and certification of structural engineering networks worldwide. Includes design, assembly, calculation, and maintenance advisory.
3. Distributor Network: Holedeck grants distributor licenses in countries where a commercial and logistics network exists. Distributors purchase materials directly and operate under periodic quality audits and training provisions.
4. HOLEDECK Zero Consulting: Collaborative optimization service with engineers, architects, and sustainable design experts to define and optimize the most sustainable and economical structural solutions per project, targeting near-zero slab emissions.

Core offering

HOLEDECK designs, manufactures and sells reusable plastic formwork molds (in ABS and polypropylene) used by builders to cast ribbed, perforated concrete slabs in situ. The patented hollow/perforated-beam configuration allows electrical, plumbing, HVAC, lighting and other building services to be routed within the structural depth of the slab, eliminating the need for suspended ceilings and reducing material consumption, construction time and waste. The offering is complemented by in-house structural engineering and project customization services.

Product overview

HOLEDECK is a structural concrete slab technology company offering a family of ribbed slab systems — both unidirectional (H-ONE) and bidirectional (HO-45) — that reduce concrete and steel consumption by over 50% while integrating building services within the structural depth. The product portfolio includes: H-ONE (perforated unidirectional slab, with 30/45/68 cm depths), H-FLAT (unidirectional without perforations), HO-45 (bidirectional perforated slab), HOLEDECK Zero (zero-carbon design methodology), HOLEDECK CUSTOMIZE (custom-designed variants), HOLEDECK Active (thermally activated slab with embedded water circuits), and Plugdeck (modular plug-and-play installation system). All systems share reusable plastic formwork (ABS or polypropylene), are executed in-situ or semi-prefabricated, and are compatible with conventional concrete, steel reinforcement, and post-tensioning.
