The concept for the Airport Metro Station 23, an important spot of Sofia metro system, is symbyosis between two main ideas.
On the one hand, linear character of the structure can separate and change the location’s current condition. The railway is supposed to be terrestrial so that it is a good decision to lift it above the ground. This intervention allows releasing the ground space between the “forest of columns” suspending the railway. The aim is maximal adaption of the new transport infrastructure to the location without interrupting the existing.
On the other hand, the key building element is inspired by the plane wing and the Bulgarian sign for metro station. It forms an arrow which is a symbol of movement and dynamic composition. The constructive unit creates its own architectural language.
For the façade cladding are used panels of glass reinforced concrete which ensure good vision and quality, freedom of shape and atmosphere conditions resistance.
