What Sieger Design does
Sieger Design (legal entity: sieger design GmbH & Co. KG) is a German interdisciplinary design agency founded circa 1990 and headquartered at Schloss Harkotten in Sassenberg, Germany. The firm operates across six integrated service lines: Design (industrial/product design), Architecture (bathroom, spa, hospitality interiors, trade fair stands), Communication (brand identity, packaging, catalogs, websites), Strategy & Design Management, and Public Relations. Its core technical offering combines product design, spatial/architectural concepts, brand strategy, and PR into a single interdisciplinary workflow, with proprietary architectural concepts including SSPS® (Small Size Premium Spa, a 6 sqm premium spa concept) and PSS™ (Personal Sensory Spaces) functioning as licensable design IP.
The company's products span industrial design collaborations with premium manufacturers — including faucet and shower series for Dornbracht (Tara, MEM, CL.1, Vaia, Lissé, CYO, COYA, Meta, Meta Square), bathroom collections for Duravit (Happy D., Happy D.2, Viu, D-CODE), lighting families for Trilux (Polaron, Polaron IQ, Arimo Fit, Creavo, Acuro), buffet systems for APS (APS Plus, FRAMES, VALO, THE GRID), bathroom furniture for Alape, coffee machines for Kaffee Partner (Ultima Duo), sun protection for Hunter Douglas, kitchens for Poggenpohl (ARC), and porcelain/lifestyle lines under the proprietary SIEGER brand in partnership with Fürstenberg. It also operates trade-fair and event concepts, and the licensed SIEGER premium lifestyle sub-brand (including Sieger by Souleway for accessories and The Sparkling 4 tumblers) sold through sieger-germany.com.
Revenue is generated through professional services (project-based design and brand consulting engagements, with pricing not publicly disclosed), alongside the SIEGER premium-brand licensing and product revenues. The go-to-market is direct enterprise engagement with industrial manufacturers and premium consumer brands, with no public investor base or external parent; the firm is family-owned and led by Managing Directors Christian Sieger (CEO) and Michael Sieger (designer), with Benedikt Sauerland also listed as Member of the Geschäftsführung. Press coverage spans 35+ countries, and the firm maintains active participation in international trade fairs including Maison & Objet Paris.
