What Cadolto does

Cadolto Modulbau GmbH is a German modular construction company headquartered in Cadolzburg, Bavaria, with a second production facility in Krölpa, Thuringia. Founded in 1890 originally as a wagon-making workshop and refocused on modular construction since 1972, the company employs approximately 260 staff across architecture, engineering, production, sales, and administration. It delivers prefabricated steel-module buildings to institutional clients, with its primary verticals being healthcare facilities, telecommunications infrastructure, data centers, and research/laboratory buildings, supplemented by education, corporate/administrative, security, and senior living applications. Since 2018, Cadolto has been a subsidiary of the Zech Group, a German construction and real estate conglomerate, which provides cross-company synergies and financial backing.

The company's core technology is a proprietary steel module construction system in which building modules up to 22 meters long, 6 meters wide, and 4.15 meters high are prefabricated in controlled factory environments. The Cadolto-specific wall construction provides extreme torsional stiffness to withstand transport stresses, enabling up to 90-100% factory pre-installation — including complete medical/lab/building services, bathrooms, furniture, lighting, and in some cases medical equipment — before site delivery. Cadolto delivers turnkey projects ranging from single-room intensive care units to multi-story clinic complexes up to 15,500 m², with documented construction-time reductions of up to 70% versus conventional methods. The company reports 790+ completed projects worldwide and an annual production output exceeding 20,000 m². Modular data center solutions achieve a total PUE below 1.2.

Cadolto's revenue model is project-based and combines one-time sales with recurring rental arrangements. The company acts as general contractor providing end-to-end delivery — planning, engineering, factory production, site installation, and commissioning — either as a fixed-price purchase or as subscription-style rental/rent-to-own (typically 4-10 years for interim facilities). GTM is direct enterprise sales through account managers, supported by long-term framework contracts with German telecommunications operators and participation in public tenders for healthcare and government projects. Referenced project values range from €4.5M (university lab) to €22.74M (COVID-19 ICU). Cadolto claims 80% market share of Germany's telecom transmitter shelters (14,000+ units installed in Germany) and is positioned as market leader in German modular healthcare construction.

Revenue model

1. Modular Building Sales (Purchase): Cadolto sells modular buildings as project-based fixed-price contracts. The company provides turnkey delivery from planning through production to handover, serving institutional buyers in healthcare, education, research, telecoms, and data centers. Projects range from single-building installations to multi-building complexes. Revenue is recognized per project milestone.
2. Modular Building Rental / Rent-to-Own: Cadolto offers buildings for rent and rent-to-own arrangements, providing flexible financing for clients who prefer not to purchase. Particularly highlighted for interim/solution buildings (e.g., the Kaiser-Franz-Joseph-Spital Vienna interim facilities rented for 4-10 years).
3. General Contractor Services (Schlüsselfertig): Cadolto acts as general contractor providing complete project delivery including architecture, engineering, factory production, site installation, and commissioning. All trades handled in-house or through controlled supply chain partners.

Core offering

Cadolto (Cadolto Modulbau GmbH) is a German manufacturer of prefabricated steel modular buildings produced at two production sites in Cadolzburg and Krölpa. The company builds turnkey steel modules — up to 90-100% pre-installed in its factories — for hospitals, data centers, telecommunications, research/laboratories, education, security, administrative, and sanitary applications. Modules are delivered to the site and assembled on prepared foundations, with the option to be relocated, repurposed, or expanded later.

Product overview

Cadolto is a German modular construction company offering steel module-based building solutions. The core product is the Cadolto Modulbau technology, which enables prefabricated, weather-independent construction with up to 90% factory pre-installation. The portfolio includes specialized modular buildings across healthcare (hospitals, intensive care units, operating rooms, radiology, patient wards, Portalklinik), research/laboratories, telecommunications stations (with 80% market share of German broadcast stations), data centers, educational facilities, administrative buildings, security buildings, sanitary/changing rooms, and senior living. Products range from turnkey complete buildings to specialized functional modules, all designed for rapid deployment (often half the conventional construction time), flexibility (expansion, conversion, relocation possible), and sustainability (materials up to 100% recyclable). The company operates two German manufacturing facilities in Cadolzburg and Krölpa, Thuringia.
