TGA Solutions PLUS GmbH

What TGA Solutions PLUS GmbH does

TGA Solutions PLUS GmbH is a privately held German engineering consultancy specializing in technical building equipment (TGA / MEP) design. Founded in 2019 and headquartered in Mülheim an der Ruhr, the firm delivers integrated services across HOAI service phases 1–8, covering consulting, planning, object and construction supervision, and a full technical scope spanning heating, cooling, ventilation, sanitary, fire protection, electrical, building automation, and renewable energy systems. The company also holds BHE DIN 14675 certification as a specialist planning office for fire alarm systems, addressing a regulated subset of building safety design.

The firm is led by four Managing Directors (Kurt W. Holler, Sascha Legenbauer, Tamer Turan, Wolfgang Voigt) supported by an external advisor (Prof. Dr. Bernd Witthaus), and operates from three engineering offices: Mülheim an der Ruhr and Bergisch-Gladbach in Germany, and Ankara in Turkey via the subsidiary Proje Limited Şirketi. Its core technology stack is described as state-of-the-art, software-based planning tooling, but no proprietary platform, AI/ML capability, or patentable IP is disclosed. The firm's competitive positioning rests on senior engineering expertise and end-to-end HOAI coverage rather than technology differentiation.

TGA Solutions PLUS generates revenue through professional-services fees on a project basis, selling directly to architects, general contractors, and investors across residential, commercial, education, senior-living, hotel, and retail construction segments. Demand generation is primarily direct (website contact forms, phone, referrals), with no channel partners or platform-style distribution. The company is privately held by its management with no disclosed institutional, PE, or VC investors.
