What kosaplaner does

Kosaplaner gmbh is an Austrian private limited company headquartered in Leobersdorf, Lower Austria, founded in 2006 by Werner Kosa. It operates as a general planning office (Generalplaner) for complex construction projects, delivering integrated services across four core disciplines: Generalplanung (overall project coordination as main planning contractor), Hochbau (structural construction of residential, commercial, educational and industrial buildings), Tiefbau (civil and infrastructure engineering covering transport networks, cycling paths and sports facilities), and Elektro- und Haustechnikplanung (in-house electrical engineering and building services design). The firm's service portfolio has been extended to include Photovoltaik und TGA, public lighting, ecological heating systems, and medical/laboratory planning.

The company's underlying technology is CAD-based architectural and engineering planning, using AutoCAD and ProVI software combined with technical building systems design for HVAC, electrical and structural work. There is no proprietary software, no API, and no disclosed AI/ML capability; the offering is human-expert professional services rather than a productized technology platform. Service delivery is project-based, with pricing quoted per engagement based on scope and complexity rather than through standardized public pricing.

Kosaplaner serves three primary customer segments: public sector clients (municipalities such as Winzendorf-Muthmannsdorf and Kottingbrunn), private housing developers and associations (notably ATLAS Gemeinnützige Wohnungs- und Siedlungsgenossenschaft), and commercial/leisure clients (Wexl Arena). Go-to-market is sales-led, combining competitive bidding for public projects with direct negotiation for private engagements, and supplemented by portfolio-driven content marketing, regional press coverage, and active participation in sustainability and industry networks including GRÜNSTATTGRAU, Klimaaktiv, respACT, and IAKS. Operations are concentrated in Eastern Austria (Vienna and Lower Austria) with projects extending across the rest of the country, and the firm is mid-sized within the 11–50 employee band. A leadership transition in January 2026 placed Johannes Pflaum as Managing Director, with department heads elevated to Prokuristen, while founder Werner Kosa remains active full-time.
