CB Richard Ellis brokered the transactions, which included the rental of 2,700 sqm for a production unit and 5,000 sqm of concrete platform.
Over the next three years, the US group plans to expand the surface rented in the Romanian park.
Ploiesti West Park was launched in 2009 and it will have a total surface of 220 hectares upon completion, following an overall investment of EUR750 million.
