Ljusrum

What Ljusrum does

Ljusrum is a privately-held Swedish multidisciplinary design studio founded in 2002 and headquartered at Ringvägen 78 in Stockholm. The firm operates with a team of approximately ten professionals spanning architects, lighting designers, interior architects, and product designers, offering four integrated service lines: Ljusdesign (lighting design), Arkitektur (architecture), Inredning (interior design), and Återbruk (recycling and circular-economy consulting). Its technical core is advanced lighting control and dynamic lighting systems that vary color temperature and intensity across the day, including proprietary circadian-rhythm lighting for elderly care facilities (notably Humana Gävle, 2017 Svenska Ljuspriset winner) and custom-designed fixtures such as the Saluståndsarmatur for Östermalms Saluhall (2020 Svenska Ljuspriset winner).

The studio serves enterprise clients across hospitality (Nordic Choice Hotels' Quality Hotel The Weaver in Mölndal, Clarion Hotel Umeå, Lydmar Hotel), healthcare (Humana), corporate offices (Tengbom, Volvofinans Bank, Nova Consulting Group, SKB), cultural heritage (Trollbäckens kyrka, Östermalms Saluhall), and public sector facilities (Malmgården, Folkbildningsrådet), with active project presence across at least eight Swedish cities though concentrated in Stockholm. Revenue is generated through project-based professional services contracts covering the full lifecycle from early sketches through implementation and monitoring; pricing is quote-based and not publicly disclosed.

The go-to-market is sales-led and relationship-driven, relying on long-term personal relationships with clients, architecture firms (Spectrum Arkitekter, Krook & Tjäder, White Arkitekter), manufacturers (Ateljé Lyktan, Orrefors), and engineering partners (WSP, Emil Lundgren AB), supplemented by an Instagram channel and editorial features in industry publications such as Ljuskultur. The firm has received three Svenska Ljuspriset recognitions (2017, 2020, 2022 honorable mention) and the Wilhelmina Skogh prize in 2023. No external funding, parent company, or M&A activity is disclosed; ownership is privately held and operating geography is restricted to Sweden.
