Siegel operates as an architectural and real estate development group based in Malmö, Sweden, with a distinctive approach that blurs traditional professional boundaries. Founded in 2009, the organization has grown to 16 employees and now comprises multiple companies spanning architecture, project development, real estate, and hospitality.
The group's defining characteristic is its site-based operational model. Rather than working from a central office, Siegel establishes temporary offices directly at construction sites, positioning small teams alongside craftsmen and clients. This approach stems from founder Cord Siegel's philosophy that architects should work investigatively and freely without intermediaries, dissolving the conventional separation between client, architect, and producer roles.
Siegel's portfolio includes residential projects like BRF Ohoj, completed in 2014 with the City of Malmö's Gröna Lans award, which combined space-efficient housing with significant greenery integration. More recently, the Promenadhuset Iggy project in Malmö's Sorgenfri district created 70 apartments designed around concepts of modern mobility, health, and environmental sustainability.
The organization partners with other real estate developers when conditions align, developing concepts collaboratively rather than pursuing projects independently. Siegel's geographic reach extends beyond Malmö throughout Sweden and internationally, though the group maintains its headquarters in the city's Spårvägen area.
Siegel's working method reflects a conviction about housing production in Sweden. Cord Siegel has stated that if 58 percent of the country's architects adopted design-build practices, Sweden's entire housing needs could be met, suggesting his operational model represents both a philosophical position and a practical response to housing challenges.
