The beginning of Vinohradská street and the atypical size of the plot - four and a half meters wide - located between the existing modernist building Nad Muzeem and the planned new building of the Vinohradská Center, encourages for an unconventional architectural concept. The result is an elegant vertical building, inserted like a slim "book" between both buildings. The compactness is supported by a subtle dark frame and a dark facade, behind which all the technology is hidden on the roof. The street facade is softened with vertical slats in golden colour - this gives the facade an interesting contrast to the dark cladding and at the same time, thanks to the "sawtooth" effect of the slats, it changes its appearance depending on the angle of view and the position of the passing observer.

The building is built directly above the Vinohrady railway tunnels, and is therefore protected from the transmission of seismic vibrations to the structure caused by passing trains. The e extension is connected to the existing modernist building.
