What Lundgaard & Tranberg Arkitekter does

Lundgaard & Tranberg Arkitekter A/S is a privately held, partner-driven Danish architecture firm founded in 1985 by Boje Lundgaard and Lene Tranberg, headquartered in Copenhagen NV. As of 2025 the firm employs 68 people across 15 partners and offers architectural consultancy in transformation, renovation, planning, and new construction, with documented projects in cultural institutions (Viking Ship Museum, Royal Swedish Opera, Natural History Museum of Denmark, Frihedsmuseet, Skuespilhuset), commercial headquarters (Novo Nordisk Foundation HQ, SEB Bank, Axel Towers), residential (Tietgenkollegiet), and urban public spaces (Ofelia Plads, Tingbjerg Multi-Purpose Arena). Its technical differentiators include a phenomenological approach to daylight, fire-tested biogenic/timber construction (CLT load-bearing structure with clay-board half-timbering achieving EI90 rating for the Novo Nordisk Foundation HQ), and heritage restoration supported by colour-archaeological investigation (Cirkusbygningen's recreation of Verner Panton's 1984 colour scheme). Revenue is earned through project-based professional-services fees won via open and invited architectural competitions, direct commissions, and pre-qualification processes for public and enterprise clients across Denmark, Sweden, Norway, and Germany. The firm has undergone a structured generational transition: 10 new partners were admitted in November 2020, co-founder Lene Tranberg stepped down from the partnership in September 2025 to become Chair of the Board, and a new executive management team was established in 2026.
