The Hafenpark Quartier Frankfurt is one of the most attractive urban development sites in Germany. The ensemble is located in the immediate vicinity of the address-forming ECB on the newly designed banks of the Main. The southern construction site, on which around 290 apartments and a hotel will be built in accordance with the urban planning framework, represents an important building block for the development of the urbanistically significant quarter in Frankfurt's Ostend. The design of the ensemble has been developed solely on the basis of the available visual relationships and optimal lighting conditions: The block is open to the south to give all apartments a view of the Main. To the west, the block edge has been reduced in height so that the courtyard receives as much light as possible in the late afternoon. Two exposed high-rise buildings with outstanding residential qualities also create an identity-creating external effect. The aim is to create the best possible combination of exterior and interior spaces and for each apartment to benefit from the exceptional location and fantastic views - up and down the Main and of the Frankfurt skyline. All apartments will also have an unusually large proportion of usable terraces and roof terraces facing the sun. Inside the block, a high-quality green open space is being created that stretches across the entire site as a sculpted meadow. A forest of sparse low trees spans this meadow. However, the continuous canopy of trees opens up into large clearings, which can be designed as lower-lying places of contemplation, as children's playgrounds, as sunbathing lawns or as meeting points paved with grand. The external appearance of the ensemble was deliberately interpreted holistically with regard to the powerful building structure of the ECB. In detail, however, the overall form is differentiated due to the diverse apartment typologies such as two-storey townhouses, apartment apartments and penthouses: parts of the building jump back and forth, are single and two-storey, balconies emerge from the façade and there are very different entrances.
