To prove that the concept was affordable with standard techniques, BIG decided that nothing would be more convincing than building it in LEGO. It happened that on the : scale model of the building, the size of a single pixel was identical to the size of the smallest one-dot LEGO brick. The model showcased the silhouette that combines the stepped figure of the traditional spire with the rationality and rigour of a functional structure.

As a contribution to the public conversation, BIG developed the BQP – turning the BQ-Expressway into a BQ-Park, while still accommodating significant vehicle flows along the route. The BQP provides a platform for adding significant new parkland along an underused corridor, while connecting Brooklyn Heights to Brooklyn Bridge Park with a preserved or re-constructed cliffside – crisscrossed by rampways, greenery, and park amenities.

The design of the new Travel Center will work with the building&#;s integrated solar cell system on the vast roof surface to harvest the sun&#;s energy, with the capability of covering nearly % of the project’s energy demand. The indoor climate will be managed through natural ventilation, and heating through underfloor heating, and the potential use of floor cooling and rainwater recycling. Conditions will be improved for public transport in the city, providing a natural flow for bicycles and pedestrians, as well as passengers switching between modes of transport. These benefits along with charging stations and places for micro-mobility will reduce citizen’s reliance on cars.

The panoramic gallery is a large open space suitable for sculptures and large installations, with the ability to be subdivided for special occasions and events. On the north end, a full-height glass wall offering panoramic views to the pulp mill and river tapers while curving upwards to form a cm-wide strip of skylight. A café is situated at this end of the gallery, where guests can enjoy snacks while taking in the view of the historic pulp mill and surrounding landscape. During the summer months, the café service area spills onto the plateau just outside.

At street level the floors are shifted backwards and forwards to create green terraces and canopies facing the park. In the middle of the silhouette, where the tower turns residential, the floor plates slide out in a spiraling movement, creating terraces and outdoor space for residents. In its upper section the tower returns to a simple stack of optimized floor plates, completing its twist to rejoin the orientation of the floors below. These inhabitable movements bring human scale from street level into the skyline, embodying the unique character of Frankfurt.
