This Rotterdam office building from 1981 with an energy label C will be sustainably transformed in 2025 into a Paris-Proof building full of facilities and services.
Upon completion, the building will become the newest flagship location for NSI’s own flexible office concept, HNK. HNK Rotterdam Alexander is located just a stone’s throw from Rotterdam Alexander intercity train station and directly adjacent to the A20 highway. To bring the building up to Paris-Proof standards, a comprehensive package of sustainability measures will be implemented. The façade will be partially replaced and upgraded for sustainability, the climate control system renovated, solar panels added, and outdoor areas enhanced with green spaces. Additionally, the energy rating will be improved to A+++. This forward-thinking approach will not only earn the building a BREEAM-NL In-Use Excellent certification but also significantly reduce energy consumption from 125 kWh/m² to 65 kWh/m², placing the building well below the Paris-Proof standard. Facilities will be added to support various ways of working, including a library, a podcast studio with high-quality equipment, a calming wellness studio, an extensive co-working area, and 14 unique meeting rooms, each designed for a specific type of meeting. On the top floor, two fully equipped event spaces will be created, along with a rooftop terrace with a bar, available for large events.
