Operating as a Generalplaner (general planner), the firm delivers all construction planning services across HOAI Leistungsphasen 1–9 from a single source, coordinating architectural, structural engineering, building physics, fire protection, and barrier-free construction disciplines through eight specialized in-house departments. Its service portfolio spans residential and high-rise construction, industrial and commercial buildings, office and administrative facilities, laboratory and pharmaceutical construction, social and educational buildings, care and healthcare facilities, modern timber construction, landscape architecture, urban and regional planning, and sports facility planning (via the Casparius Sportanlagenplanung sub-brand). The Hartung & Ludwig Gruppe operates across three German locations—Weimar (HQ), Leipzig (via wholly-owned subsidiary snp Architekten + Ingenieure GmbH), and Erfurt (via Casparius)—with 48 active projects and a 371-reference completed portfolio.

The firm serves a mix of commercial, public-sector, and private clients, with housing cooperatives and real estate developers flagged as the primary segment, complemented by industrial, educational, healthcare, and municipal customers. Named engagements include Evangelische Schulstiftung in Mitteldeutschland, Wippertal Wohnungsbau, AWO AJS gGmbH, Gebäude- und Wohnungsbaugesellschaft Wernigerode (GWW), and Zentralklinik Bad Berka. Revenue is generated through professional services fees quoted on a per-project basis under HOAI; pricing is not publicly disclosed. Go-to-market is direct enterprise field sales via project-based engagement with housing cooperatives, private developers, real estate companies, municipalities, schools, and healthcare providers across Germany, with primary concentration in Thuringia, Saxony, and Saxony-Anhalt.

Ownership rests with Managing Directors and shareholders Dipl.-Ing. Architektin Anne Hartung and Dipl.-Ing. Ralf Ludwig, with no external institutional or private-equity backing disclosed. The firm is family-owned and reports being a steadily growing mid-sized company. Strategic positioning emphasizes single-source responsibility, sustainability (membership in the proeco sustainable renovation network), BIM methodology, and complementary adjacencies including a minority investment in LOKK UG (a cloud/AI platform for urban and regional development), Chamber of Commerce memberships in Chile and Uruguay, and the BIM-MIT! external training workshop series. A dedicated Head of Business Development and Sales (Heiko Sittig) was appointed to drive growth beyond the firm's Central Germany core.
