Ojarannan Rakennus Oy

What Ojarannan Rakennus Oy does

Ojarannan Rakennus Oy is a privately held Finnish construction company headquartered in Koski, Finland, founded in 2004. According to the available firmographic data, the company operates in three core service areas: building contracting, housing production, and indoor air repair services. The indoor air repair vertical is a distinct specialization within the Nordic construction market, addressing moisture, mold, and ventilation-related remediation in residential buildings — a regulated and growing segment driven by Finland's indoor climate standards. The firm is small, with a reported headcount band of 11–50 employees, suggesting a regional subcontractor or boutique general contractor footprint rather than a national operator.

No detailed information was recoverable from the company's website (https://www.ojaranta.fi) or any associated source material; the web content consisted solely of a verification/loading page with no corporate, product, pricing, or organizational detail. As a result, the company's underlying technology stack, proprietary building methods, supplier relationships, certification status (e.g., RALA in Finland), customer mix, revenue model, project pipeline, and ownership structure cannot be characterized from the available evidence. The short_description confirms for-profit status and private ownership, with no disclosed subsidiaries, parent entities, or funding history. Investors evaluating this name should treat the absence of primary-source corporate disclosure as a material due diligence gap and seek direct management outreach or Finnish trade registry (YTJ / Kaupparekisteri) filings to confirm scale, financials, and project references.
