What Nøhr & Sigsgaard Arkitektfirma does

Nøhr & Sigsgaard Arkitektfirma is an independent Danish architecture firm headquartered in Copenhagen (CVR 17641875), structured as an aktieselskab. The firm operates across three core service areas: the development of educational environments (schools, daycare institutions, gymnasiums, and universities), the transformation and renovation of cultural-heritage buildings (including listed functionalist properties), and the Royal Building Inspectorate mandate for Inspectorate 3 in Copenhagen, covering state-owned properties such as Amalienborg, Fredensborg Castle, and Statens Museum for Kunst. The firm is a founding partner of the TRUST strategic building partnership with Copenhagen Municipality, through which it developed the original methods, tools, and processes for collaborative delivery of schools, daycare institutions, and residential care facilities.

The firm's revenue model is professional services — project-based fees generated through public tenders, architectural competitions, and direct commissions. Distribution is entirely direct-to-client (no intermediaries); all engagements are won through Danish public procurement processes, strategic partnerships, or sole-source commissions. Project delivery is multi-disciplinary, with engineering consultancies (e.g., Rambøll, Niras, EKJ, Norconsult, Dominia), landscape architects (1:1 Landskab, Kragh & Berglund, Lytt Architecture), and conservation specialists (Center for Bygningsbevaring i Raadvad) embedded into each project team. The firm bears no parent company, no external shareholders, and is partnership-managed by Mads Koch (Partner, Office Manager), Berit Thorup, and Julian Heick, with Jacob Ingvartsen heading the cultural heritage department as Royal Building Inspector.

The customer base is concentrated almost exclusively in Danish public sector — primarily Copenhagen Municipality (via Byggeri København and Københavns Kommune), with adjacent municipalities (Gladsaxe, Gentofte, Lyngby-Taarbæk, Vallensbæk) and a single gymnasium client (Borupgaard Gymnasium). The firm's competitive positioning rests on documented heritage credentials (European Heritage Awards/Europa Nostra 2023 for Friluftsskolen), pedagogical-design expertise (Årets Skolebyggeri 2019), and the regulatory appointment as Royal Building Inspectors — a convergence of reputation, institutional knowledge, and statutory mandate that is difficult for competing firms to replicate.
