Conceptually, the project is a compilation of three primary elements: a base, a roofscape and two towers. The base gathers the project's public and urban attributes, while the two towers accommodate a hotel and office spaces with views of Hamburg. An undulating roof landscape binds these two elements together and looks to offer a softer and inviting quality to the proposal.

The base level hosts the public realm and new Altona North train station, creating contact with adjacent streets and urban spaces. It looks to provide the backdrop to a wide range of public functions that create life and activity within a station; such as cafes, restaurants, shops, fitness facilities, bicycle parking, waiting areas and entrance lobbies.

The connective roof not only gathers together the different elements of the project but also provides a canopy for many outdoor public functions at ground level. It allows the covered area of the forecourt to be used 365 days a year for cafés, farmers’ markets and cultural events. The roof itself hosts a green park above, with covered outdoor spaces for the hotel and offices. The roof landscape embodies a collective and progressive vision of reinforcing Hamburg’s green credentials.
