Subirachs Construccions

What Subirachs Construccions does

Subirachs Construccions (legal entity: SUBIRACHS, S.L.) is a privately held, family-owned construction company headquartered in Centelles, in the Osona region of Barcelona province, Catalonia, Spain. Founded approximately in 1945, the firm is now in its third generation of operation, led by founder-director Angels Subirachs and master builder Pep Vivet. The company specializes in custom residential construction, bioconstruction, rehabilitation and restoration of heritage Catalan properties (masías), roofing, custom porches, and the traditional Volta Catalana vault technique. Its service portfolio is delivered through a 'Llaves en mano' (turnkey) model that provides a single interlocutor across architecture, permits, construction, and interior design.

The underlying technology combines conventional construction with bioconstruction methodology — natural, non-toxic materials including wood, earth, straw, stone, lime, bamboo, and hemp — and integrates geobiology analysis through the GEOBALANCE sub-brand to detect and neutralize harmful environmental energies. Distinct technical offerings include the Volta Catalana vault, traditional restoration of masías and chapels, and the AGNI brand of artisanal wood-fired ovens built in situ with clay from Pereruela. A distribution partnership with Italian manufacturer VALORIANI extends the offering into professional-grade ovens.

The revenue model is project-based with custom quote pricing; there are no publicly disclosed prices. The go-to-market is sales-led and direct, driven by website contact forms, phone inquiries, email, and organic social presence on Facebook, Instagram, and Pinterest. Primary customer segments are individual homeowners seeking custom or sustainable builds, heritage property owners requiring restoration of traditional Catalan architecture, and homeowners seeking custom porches or outdoor structures. The geographic scope is regional across Osona, Barcelona province, and the rest of Catalonia for standard projects, with nationwide Spain coverage specifically for bioconstruction and modular construction projects. The firm operates with 1–10 employees and has no external investors, parent company, or disclosed funding history.

Scale indicators3 records

Recent moves6 records

Expansion highlights4 records

Emerging players

• Hempitecture: US-based sustainable building materials and bioconstruction specialist focused on hemp-based products. Comparable to Subirachs' hemp-inclusive bioconstruction approach but operates in a different geography and at earlier commercialization stage.

Direct peers

• Voltes Ecoarquitectura: Catalan cooperative specializing in ecological architecture and bioconstruction using natural materials. Closely comparable to Subirachs on bioconstruction methodology and Catalan regional focus.
• Naturbuild: Spanish firm specializing in bioconstruction, natural materials, and healthy home design. Comparable to Subirachs on sustainable construction services and natural-material methodology, with national Spanish reach similar to Subirachs' bioconstruction coverage.
• Celobert: Catalan sustainable architecture and construction firm focused on bioconstruction, energy efficiency, and natural materials. Directly comparable to Subirachs in the Catalonia bioconstruction niche, with similar target customers and sustainability positioning.

Broad incumbents

• Construcciones Rubau: Established Catalan general contractor offering residential, civil, and industrial construction. Comparable as a regional building firm operating across Catalonia and Spain, but with much broader scope and scale than Subirachs' boutique residential focus.
• Constructora San José: Major Spanish construction group with residential building capabilities alongside commercial and infrastructure work. Comparable as a general building contractor operating in Spain, though at vastly larger scale and with a broader portfolio than Subirachs.
• Grupo ACS / Dragados: One of Spain's largest construction and infrastructure groups with residential building exposure. Comparable in core construction activity but operates at incomparable scale and serves primarily large institutional and infrastructure clients.

Regional players

• Acció Urgel: Catalan regional construction and building services provider. Comparable as a Catalonia-based construction firm serving similar residential and rehab customers, though broader in scope and less specialized in bioconstruction.
