Sea container structure as an addition to existing building. The project proposes construction of two partially underground levels plus adding two additional storeys above with metal modular system and reinforcing metal elements as well as a 5-storey tower, built of a metal structure and curtain wall. About 70% of the building materials are recycled which contributes to reducing the carbon footprint. The building is highly energy-efficient and sustainable due to the system's flexibility.
