What 3h építésziroda | 3h architects does

3h építésziroda (3h architects) is a Budapest-based architectural firm founded in 1994, operating with a small team of 11-15 professionals. The practice specializes in contextual, sustainable, and historically-sensitive design, with a project portfolio spanning commercial, residential, civic, cultural, and ecclesiastical typologies. Notable commissions include the renovation of the Pannonhalma Basilica in partnership with John Pawson, the Szeged Cathedral with Váncza Művek, and the Bem Center (2024 Fiabci award winner), alongside projects across Hungary, Central Europe, and Nordic/Alpine markets.

The firm's underlying offering is professional architectural services — feasibility, design, documentation, and project oversight — delivered through a boutique principal-led model. Technical delivery relies on conventional architectural workflows rather than proprietary technology platforms; competitive differentiation is built on design quality, heritage sensitivity, sustainability credentials (DGNB Gold), and recognition through awards including Mies van der Rohe nominations and the A' Design Award.

The business model is fee-for-service, project-based billing on commissioned work from a mix of real estate developers (Futureal, ECE Budapest), corporates (Audi Hungaria), financial institutions (OTP Bank), and academic/public clients (MOME). Revenue is lumpy and tied to discrete commissions rather than recurring contracts, with cross-border projects supplementing the core Hungarian pipeline to diversify geographic exposure.
