Planwerk

What Planwerk does

Planwerk (legal entity: planwerk Schilling Lemmer Architektinnen PartGmbB) is a privately held architecture firm headquartered in Wuppertal, North Rhine-Westphalia, Germany, founded in 2006 by Yvonne Schilling and Svenja Lemmer. The firm is registered with the Architektenkammer Nordrhein-Westfalen and operates under a PartnerschaftsGmbB legal structure since 2016. The team disclosed on the company website consists of the two co-founder architects plus one part-time student worker, though firmographic data lists 42 employees, a discrepancy that materially affects scale assumptions.

The firm delivers full-service architectural planning covering all eight performance phases (Leistungsphasen 1-8) under the German HOAI fee structure for architects and engineers. Services span from basic analysis (Grundlagenermittlung) and preliminary planning through design, permitting, execution planning, tender preparation, bidding assistance, and construction supervision, covering both new construction (Neubauten) and renovation of existing buildings (Baumaßnahmen im Bestand). The firm emphasizes functionality, economic viability, sustainability, early cost estimation, and close coordination with specialist planners.

Planwerk serves two customer segments on a horizontal basis: private clients (Private Bauherren) and commercial clients (Gewerbliche Bauherren), with projects sourced through direct engagement and client referrals. Revenue is generated via professional-services, project-based billing at individually quoted rates. There is no proprietary technology, no software products, no AI/ML capability, no external investment, and no disclosed financial figures. Geographic reach is limited to the Wuppertal/NRW region.
