What 3XN does

3XN is a Danish architectural practice founded in 1986, headquartered in Copenhagen, with 51–100 employees and an international project portfolio spanning Denmark, Germany, Australia, and Switzerland. The firm designs complex public and sports facilities, applying sustainable design methodologies including adaptive reuse, circular economy principles, modular construction, asymmetrical structural forms, and green-roof integration. Signature projects include the SAP Garden multi-use arena in Munich (10,700–11,500 adaptable seating, three training rinks), the Sydney Fish Market urban renewal at Blackwattle Bay, and the Tilia Tower sustainable skyscraper in Malley, Switzerland, which employs LC³ low-carbon cement reducing CO₂ emissions by up to 40%.

3XN's underlying capability is methodological rather than platform-based: the firm has developed proprietary approaches to circular-economy architecture, including materials passports and adaptive reuse strategies, that have been demonstrated across its project portfolio. The technology stack is conventional architectural design (BIM, parametric modeling) augmented by sustainability-driven design protocols rather than software products.

The business model is professional services. 3XN earns revenue through design fees on large-scale public infrastructure commissions, typically structured as fixed-price or percentage-of-construction-cost contracts, secured via direct enterprise/government sales. The go-to-market motion is field-based enterprise selling to sports organizations, league tenants, and government infrastructure agencies rather than consumer-facing marketing. Marketing operates primarily through architectural trade publications and industry awards. Pricing is not publicly disclosed and is negotiated per project based on scope, complexity, and construction budget.
