TrIIIple is an imposing and widely recognizable high-rise, located directly on the Danube Canal in Vienna’s third district. The design allows for floor plans of the highest flexibility, facilitating diverse apartment concepts with layouts that can be determined individually. Due to an intelligent floor plan geometry, many floors have more than just the classic four corners, which results in an abundance of apartments with two-sided lighting. Maximum open space connection is achieved due to the generous floor-to-ceiling glazing of the windows, and the tower’s reinforced concrete skeleton construction enables balconies all around the perimeter.

The development offers occupants a unique combination of services, with concierge, event kitchen, community terrace, library lounge, barbecue lounge, rooftop pool, and laundry facilities. It also has in-house infrastructure with stores, restaurants, cafés, and a kindergarten, and has ideal connections to the city center via the U3 Erdberg and Schlachthausgasse subway stations. And with numerous landscaped open spaces onsite and immediate proximity to the Green Prater, a major city park, the development provides tenants with many opportunities and easy access for leisure activities.

To make the air conditioning of the residential units as sustainable as possible, the power of water and its cooling properties are used to regulate the temperature. By means of a river water extraction structure, up to 1,000 cubic meters of water per hour is taken from the Danube Canal. With the help of a heat pump, the project uses the thermal potential of that water to heat and cool the tower. The plant generates 11.7 million kWh of heat and 6.2 million kWh of cold per year, and the power supplied to customers comprises 9,000 kW of heat and 6,000 kW of cold. This saves around 3,100 metric tons of CO2 per year.
