What Wimmerbau.de does

F. Wimmer Baugeschäft und Zimmerei GmbH (operating as WimmerBau) is a privately held German construction company headquartered in Passau, Bavaria, with approximately 160 employees and 60 years of operating history. The company operates as a Generalunternehmer (general contractor) delivering turnkey construction projects across residential (single-family homes, multi-story apartment buildings), commercial (office buildings, retail centers), industrial (manufacturing halls, parking structures), and civil engineering (bridges, towers, underground works) segments. Core product lines include Schlüsselfertiges Bauen (turnkey construction), Einfamilienhausbau, Geschosswohnungsbau, Industriebau, Parkhausbau, Ingenieurbau, Tiefbau, Typenhäuser (model home series), Umbau/Sanierung, Abbrucharbeiten, and Holzbau (timber construction using CLT Massivholz elements). The firm holds unrestricted building permit submission authorization in Germany and Austria, certified fire protection expert status, and qualified specialist certifications in concrete repair, water management act (§19 WHG) work, and asbestos removal.

The company is vertically integrated across all major construction trades — masonry, concrete, carpentry/joinery, civil engineering, demolition, and interior finishing — with the wholly-owned Schreinerei Schatzl GmbH subsidiary providing bespoke furniture and joinery at the same Passau address. In-house engineering uses SEMA software for timber framing and Allplan for structural planning. Architects and engineers deliver full building permit submission, structural analysis, sound/thermal protection, and energy consulting in-house, including KfW subsidy support. Beyond construction services, the company operates the WimmerWohnräume showroom for tiles, bathrooms, and wood flooring, and actively develops and sells real estate (apartments and building plots) primarily in Passau and Lower Bavaria, with the 2024 launch of the KfW-40-standard Wohnanlage Carossastraße in Passau-Heining exemplifying this developer role.

Revenue is generated through fixed-price construction contracts (one-time project licensing per project), real estate sales (per unit and per square meter at 125-165 EUR/sqm for land), and showroom retail for interior finishing products. Go-to-market is sales-led and regional, relying on 60 years of local reputation, referrals, organic search, direct inquiry via website/phone, and reference model home exhibitions. The customer base spans private individuals, enterprise (ZF Passau, Norma, B&B Hotel, Eichberger Schiffsreisen, Paul Nutzfahrzeuge), public/government (Landratsamt Passau, Kinderklinik Passau), and real estate developers (RMI Immobilien, RT-Immobilien). Managing directors Walter Donaubauer and Dr.-Ing. Uli Donaubauer lead the company, with no external investors or parent company disclosed.
