The new Prague-Bubny railway station building is part of the planned high-speed rail line to Václav Havel Airport. The first phase of construction includes the section from the Negrelli Viaduct to the Prague-Bubny railway station and continues over a flyover to the new Prague-Výstaviště stop.

The spatial layout of the Praha-Bubny station is determined by the tracks leading to the airport and to Kralupy; the vertical layout is based on the requirements for a grade-separated intersection of the connecting flyovers with Bubenská Street and the connection to the Negrelli Viaduct. The railway station is designed with two concourses (south and north) and an underpass in the center of the structure.

The design of the Praha-Bubny railway station itself is conceptually based on the Final Design Documentation (DUR). Discussions regarding modifications to the design were prompted primarily by a new urban study of the entire adjacent Bubny–Zátory development area (by Thomas Müller Ivan Reimann Architekten and Pelčák a partner architekti), which defines new significant urban spaces in the vicinity of the Vltavská metro station. These include, in particular, the Vltava Philharmonic Hall building in the southern forecourt of the railway station, a plaza along the entire eastern edge, and the Memorial of Silence in the northern part of the area, which incorporates the original historic Prague-Bubny railway station building. The new railway station, together with the philharmonic hall, will become the natural center of the emerging neighborhood that will connect lower Holešovice with Letná.

A key new requirement for revising the design was to design the platform canopy in such a way that this structure would allow for future construction above the track bed itself. The building’s physical development is thus divided into two phases over time. The so-called “commissioning” phase, during which the railway station itself is operational but connections and links to all areas of the surrounding territory are not yet active, and the future Phase 2, during which the building itself will be constructed above the tracks and along the western edge of the station without significantly restricting operations. The building is intended to serve an administrative function, supplemented by retail spaces on the ground floor. The future building may be connected via an underground passageway in the northern concourse (1PP) to the new concourse of the Vltavská metro station. A striking architectural feature of the railway station building will be the arcade running along the entire eastern edge toward the new square, which, with its “grand scale,” references the tradition of the station as a significant public building in the area.

The concourses are designed as simple, clearly laid-out spaces whose floor plans are organized around the main circulation corridors between the entrances and platforms. These pedestrian corridors will be lined with retail units. Both the south and north concourses are connected to the platforms by three fixed staircases and four escalators, and three elevators are planned in each concourse to ensure barrier-free access. The main technical block of the railway station is located in the north concourse. Upon commissioning, the central underpass will serve solely as an access route to the platforms and is structurally prepared for the future addition of technical and retail spaces. The underpass is connected to the platforms by three staircases.

In the first phase, the roof of the railway station above the south concourse is designed as an observation deck. It is accessible via a four-flight staircase from the first platform, and since the station will be the first building in the redevelopment area, the terrace could serve as an information point offering views of the city and the surrounding neighborhood currently under development. The walkable area is designed as a wooden deck, and in the center of the terrace is a visible green roof featuring elements of intensive greenery.
