M. Haseitl Baugesellschaft mbH & Co. Betriebs-KG

What M. Haseitl Baugesellschaft mbH & Co. Betriebs-KG does

M. Haseitl Baugesellschaft mbH & Co. Betriebs-KG is a family-owned, regional construction company headquartered in Schongau, Upper Bavaria (Oberbayern), Germany, founded in 1966 by Matthäus Haseitl. The firm operates an integrated four-line construction platform: Tiefbau (underground and infrastructure construction), Hochbau (above-ground building construction), Schlüsselfertigbau (turnkey construction as general contractor), and Immobilien (property development). Its technical differentiator is Holzhybridbauweise — a wood-concrete hybrid construction method combining solid timber walls with concrete and steel components, achieving KfW-Effizienzhaus 40 and 55 standards — deployed primarily in its own residential developments. The company runs an in-house Tiefbau division with dedicated machinery and approximately 150 colleagues across office and site functions, supported by a training pipeline of 172 apprentices and an apprentice workshop established in 2024.

Revenue is generated through three primary streams: project-based construction service contracts for Tiefbau, Hochbau, and Rohbau work (awarded via public tenders and direct private negotiation); fixed-price and cost-plus general contracting for Schlüsselfertigbau projects; and direct property sales of Eigentumswohnungen from its affiliated project development entities (e.g., Haseitl Reßle Projektgesellschaft, M. Haseitl Projektentwicklung König-Ludwig-Straße). Customer segments split between public-sector clients (Staatliches Bauamt Weilheim, Stadt Weilheim, Gemeinde Berg, Stadtsparkasse München) and private/institutional developers (Ten Brinke, Aichach S7 GmbH) plus end-buyers of its own-developed apartments. Go-to-market is relationship-driven, sales-led, and field-based, with project acquisition led by Geschäftsführung and senior project managers, supplemented by a real estate broker channel (Ruf Immobilien) for selected developments. Distribution is regional, concentrated in Upper Bavaria across Schongau, Peiting, Marktoberdorf, Munich, Mittenwald, Aichach, Weilheim, and Oberammergau.

The firm is privately held with a Kommanditgesellschaft structure (HRA 56241, Amtsgericht München), represented by M. Haseitl Baugesellschaft mit beschränkter Haftung (HRB 50464) under managing directors Sven Keller and Stefan Weber since 2026, succeeding long-tenured Geschäftsführer Peter Schrehardt. No external institutional capital, PE/VC backing, or public listing is evident; the company appears entirely self-financed and family-controlled, with 60 years of continuous operation, 1,938 completed construction sites, and ~993,500 m² of built residential floor area as accumulated track record.

Revenue model

1. Construction Services (Tiefbau, Hochbau, Rohbau): Revenue is generated through construction service contracts for Tiefbau (underground/earthworks), Hochbau (above-ground construction), and Rohbau (structural shell) work. Projects are awarded through public tenders and private contracts. Revenue is project-based and primarily one-time per project, with ongoing relationships from repeat clients.
2. Schlüsselfertigbau (Turnkey Construction / General Contracting): As general contractor, M. Haseitl manages the full construction process for turnkey delivery, coordinating all trades. Revenue is earned as a fixed-price or cost-plus contract for the complete project delivery.
3. Immobilien / Property Development (Bauträger): M. Haseitl acts as a property developer (Bauträger), developing residential projects (Eigentumswohnungen) for sale to end buyers. Revenue comes from property sales. The company retains an affiliated project company for each development (e.g., Haseitl Reßle Projektgesellschaft, M. Haseitl Projektentwicklung). Sales are conducted both directly and via real estate brokers such as Ruf Immobilien.
