What Add arkitekter does

Add arkitekter AS is a Norwegian architecture firm founded in 1998 by Geir Dyrvik and Knut Fabritius (initially as Dyrvik Arkitekter), headquartered at Nedre Vollgate 5 in central Oslo. The firm employs 24 people and provides architectural services across urban planning, residential, commercial, and public building typologies, with particular emphasis on transformation, adaptive reuse, and sustainable design. It operates primarily in the Norwegian market with a documented project footprint across at least 12 cities including Oslo, Drammen, Tønsberg, Porsgrunn, Sandvika, Fornebu, Moss, Trondheim, and Sarpsborg.

The firm's service portfolio spans six areas: architectural design (arkitektoniske tjenester), urbanism and planning (urbanisme og planlegging), residential projects (boligprosjekter), public buildings (publikumsbygg — courthouses, sports facilities, cultural centers, educational buildings), commercial buildings (næringsbygg), and transformation/reuse (transformasjon og ombruk). Documented technical competencies include passivhaus/passive house design, BREEAM certification expertise (Nor ratings from "good" to "excellent"), prefabricated concrete construction, mass timber construction, and FutureBuilt circular economy pilots. Notable completed projects include Nasjonalmuseet (54,600 m² BTA, completed 2021), Sundtkvartalet (35,000 m² BTA office), Krydderhagen (500 apartments), Gregers kvartal (258 apartments with BREEAM-NOR "good"), and Norway's tallest mass timber building at Blindern (40 m). The firm's expertise in courthouse design is specifically recognized, evidenced by the 2026 Betongelementprisen award for Tønsberg tinghus.

Add arkitekter generates revenue through project-based professional services for architecture, urbanism, planning, and design. Work is acquired via three channels: architectural competitions (the primary pipeline), direct commissions from established developers and government agencies, and public procurement for municipal/state projects. Major clients include Statsbygg, OBOS, Skanska, NCC, Entra, KLP Eiendom, Bane NOR Eiendom, and multiple municipal governments (Oslo, Porsgrunn, Fredrikstad, Moss, Notodden). Pricing is not publicly disclosed but follows standard architectural professional fee structures tied to project scope and complexity. The firm has recently transitioned from a partner-managed model to a leadership structure with defined roles not tied to ownership.
