DIIIP

What DIIIP does

DIIIP Projekt GmbH is a Cologne, Germany-based architecture and spatial design collective founded by registered architect Jochen Reetz, operating as a cross-disciplinary practice that combines architecture, communication design, media design, and craftsmanship. The firm delivers integrated spatial solutions across four core service lines: full architectural services covering all German HOAI work phases (LP 1-8) for residential, commercial, and cultural buildings; interior design including complete renovations and spatial restructuring; branded spaces for corporate clients including trade fair stands, showrooms, and event installations; and temporary event architecture such as pop-ups and temporary museums. Signature capabilities include multimedia spatial experiences and event concepts (NEXT, Transform I, Into Spaces), demonstrated at scale through projects like the ~1,000 m² NEXT installation at Design Post Köln.

The customer base is bifurcated between private residential clients seeking home architecture and renovation work, and corporate clients spanning manufacturing (Interprint, Westag, Birkenstock, Hülsta, Häcker Küchen), consumer goods and retail (Melitta, REWE Group, TOOM Baumarkt, Hussel), telecommunications (Telekom Deutschland), publishing (Bastei Lübbe), and waste management (REMONDIS). A particularly deep, multi-year relationship exists with Interprint GmbH, for whom DIIIP has executed at least five documented projects between 2014 and 2024. The firm also maintains a recurring-revenue coworking facility — approximately 340 square meters of loft-style workspace branded A310 — at its headquarters on Aachener Strasse 310 in Cologne.

DIIIP's business model combines project-based professional services revenue with subscription/recurring revenue from A310 coworking. Distribution is direct and relationship-driven, with projects acquired through competitive bidding, portfolio presentations, and referrals within the German architecture and design community. The firm markets primarily through its portfolio website and earned media in publications such as DETAIL magazine and Event Design, supplemented by industry recognition including a 2025 Red Dot Design Award for the Westag BAU25 messestand and 2017 trade-fair design acknowledgments. Geographic reach is primarily Germany, with concentrated activity in North Rhine-Westphalia and project presence in Hamburg, Berlin, and Bavaria.
