Halvorsen & Reine

What Halvorsen & Reine does

Halvorsen & Reine AS is a Norwegian civil architecture firm founded on August 15, 1974, originally as Halvorsen, Reine, Waage, and headquartered in Drammen, Norway. The firm provides comprehensive architectural services including building design, renovation and rehabilitation, master planning, and regulatory/development planning across all building categories — residential, hotels and spa, commercial and office, mixed-use, industrial, healthcare, and civic projects. It maintains a stable team of approximately 20-30 architects and operates primarily as a coordinating architect within multidisciplinary teams on most engagements.

The firm's revenue model is straightforward professional services fees, custom-quoted on a per-project basis. Customer mix spans enterprise hospitality operators (The Well, Farris Bad, Son Spa, Støtvig Hotel, Skarsnuten), mid-market and enterprise real estate developers (Storsand Bolig, JM Norge, Gjelsten Bolig, Rortunet, Vinkl, Sølvparken), public/religious entities (Ringerike Kirkelig Fellesråd for Hønefoss Church), and private individuals. Projects are acquired through direct client relationships, referrals, and architectural competitions. The firm has no proprietary technology platform, no AI/ML capabilities, no app, and no API surface — its offering is wholly services-based.

Ownership is private and employee-held, with the ownership structure expanded to include employees in 1997 and maintained since. The firm is co-led by Aina Lian and Øystein Rognebakke, who became daily managers and board chairs in 2016. In 2024 the firm celebrated its 50th anniversary and relocated to new offices at Gamle Kirkeplass 7 in Drammen. Geographic scope is domestic Norwegian only, with project activity across more than 20 municipalities.
