Østermark Entreprenørforretning

What Østermark Entreprenørforretning does

Østermark Entreprenørforretning A/S is a privately held Danish construction contractor headquartered in Holstebro and founded in 1977. The firm delivers comprehensive construction services across all building phases, structured around five core service lines: Jord & Kloak (earthwork and drainage), Beton (concrete), Murerarbejde (masonry), Tømrerarbejde (carpentry), and Hovedentreprise (main contracting). It operates as both a specialist trade contractor and main contractor, with a flat organizational structure designed to enable rapid decision-making and efficient project management. The company employs between 51 and 100 staff and is owned by a group of seven owner-managers (indehavere), including the CEO, Board Chairman, Finance Director, Project Director, Tender Manager, Master Carpenter, and Project Manager/Building Constructor, supported by additional project managers, a construction manager, and an estimator.

The company serves private, commercial, industrial, and public sector clients throughout Denmark, with a project portfolio that spans residential builds, industrial warehouses, district heating plants, biogas facilities, wind turbine foundations, solar infrastructure, hospitals, airports, schools, and hospitality projects (including Legoland Hotel). Notable enterprise clients include Pension Danmark, Copenhagen Airport (CPH), OUH Odense University Hospital, Merlin Entertainments, Siemens, European Energy, Nature Energy/Xergi, and Nomi4S. Project scope is technically demanding — including a 20 MW heat pump installation, 2,600 m³ concrete pours completed in under 24 hours, and 73-meter concrete tunnels — and has been recognized with the 'Årets byggeri 2024' (Building of the Year 2024) award for the Håndværkerkollegiet project in Horsens.

The business model is project-based professional services revenue, generated through direct sales-led customer engagement with quotes provided per project. Customers contact the firm via phone (+45 9685 4600) or email ([email protected]), and projects range from small private residential tasks to multi-million-euro main contracting assignments. Distribution is direct-to-customer with no intermediaries; supporting engineering consultancy partnerships (MOE, Midtconsult, MJT Rådgivning) and technology partners (Xergi) are used on technically complex builds. The firm publishes ESG responsibility reports (Ansvarlighedsrapporter) and maintains web/social presence (oestermark.dk, LinkedIn, Facebook) for top-of-funnel visibility. Revenue is not publicly disclosed.
