Kjær Knudsen A/S

What Kjær Knudsen A/S does

Kjær Knudsen A/S is a Danish construction and renovation contractor founded in 1931, headquartered in Brøndby in the Copenhagen area, and operating with approximately 48 employees. The company provides roof and facade renovation, interior renovation, heritage restoration, and ongoing service/maintenance, with in-house carpentry (tømrer) and masonry (murer) production capabilities. Its core customer segments are Danish municipalities and public institutions (Københavns Kommune, Helsingør Kommune, Roskilde Kommune, Gentofte Kommune, Solrød Kommune, among others), housing associations (A/B Rosenlund, A/B Lille Vibenshus, PrivatBO, and numerous andelsboligforeninger), social housing companies (Lejerbo, Domea, AKB), and a smaller set of private clients (Georg Jensen, Nobis Hotel, Sankt Therese Kirke).

The firm's competitive positioning rests on nearly a century of accumulated craftsmanship in heritage building restoration — including projects on properties dating back to 1879 — combined with modern energy optimization and fire-safety upgrade capabilities. Notable recent projects include the A/B Rosenlund renovation (Kr. 68M, 4,500 sqm), the Inco-bygningen restoration in Kødbyen (Kr. 39M, 7,500 sqm), and a "first-in-Denmark" climate-securing facade at Plejecentret Klarahus (Kr. 18M). Projects range from Kr. 175,000 service jobs to multi-year main-contractor engagements exceeding Kr. 60M.

In April 2022, Kjær Knudsen was acquired by Fasadgruppen Group AB, a Nasdaq Stockholm-listed Nordic facade conglomerate with 2,000+ employees and 50+ sister companies across Scandinavia. The acquisition provides Kjær Knudsen with cross-border collaboration capacity, group-level best practices, and access to larger Nordic tenders, while the company continues to operate as a standalone Danish operating entity under the Fasadgruppen umbrella. Revenue is generated entirely through project-based fixed-price contracts as main contractor (hovedentreprenør) or subcontractor, with public-sector work won through formal tenders and private/housing-association work won through direct relationships and referrals.
