What Eggen arkitekter does

Eggen arkitekter AS is a privately held architecture firm headquartered in Trondheim, Norway, founded in 1963 by Nils Henrik Eggen. Operating as Eggen arkitekter AS since 1997 under co-owners Jon Morten Breidablik and Iver Corneil, with Vebjørg Ekseth as current Managing Director, the firm employs 17 professionals delivering services across five disciplines: architecture, interior design, urban/regional planning, sustainability consulting, and historic rehabilitation. The firm applies BIM-based multidisciplinary coordination (combining planners, architects, and interior architects) and has built specialized expertise in mass timber construction, BREEAM-related sustainability work, and historic preservation.

The firm's project portfolio spans cultural buildings, educational facilities (notably NTNU Helgasetr completed 2024), healthcare and religious structures (including St. Olav domkirke, completed 2016), student housing (Studentersamfundet expansion, 2024), and rehabilitation of protected historic buildings such as Erkebispegården and Besøkssenteret ved Nidarosdomen. Technology and methodology center on BIM coordination, user participation workshops, and interdisciplinary design processes, with a stated sustainability philosophy emphasizing reuse of materials, mass timber, and lifecycle value.

Eggen arkitekter generates revenue through professional service fees on project-based commissions. Go-to-market is sales-led, relying on competitive tendering for public sector work and direct commissions for private clients. The customer base is concentrated in the Trøndelag region and dominated by public sector clients including Trondheim kommune, Statsbygg, NTNU, and other governmental bodies, with private sector work in residential and commercial projects representing a secondary stream. Marketing is minimal, relying on project portfolio visibility, industry awards (multiple Trondheim kommunes byggeskikkpris, Murverksprisen, international Brick Award finalist), and professional referrals rather than outbound demand generation.
