20th-century design
The New Stage Was Designed by Karel Prager for a Multimedia Theatre
Prague City Tourism says Karel Prager designed the New Stage and that it was created for Laterna Magika.
New Stage, Národní třída

Its design belongs to a multimedia-theatre project rather than an attempt to imitate the older theatre next door.
Do not expect a historical imitation
The New Stage makes more sense when you stop asking why it does not resemble the historic National Theatre. Prague City Tourism identifies Karel Prager as its architect and says the building was created for Laterna Magika, the multimedia theatre. That gives the architecture its own programmatic logic. The building belongs to a later cultural moment with different ideas about theatre, media and public space.
Read the building as a deliberate contrast
Modern additions beside historic monuments are often judged as if harmony means visual imitation. A better question is what kind of relationship the new building chooses. At the New Stage, look for strong geometry, material contrast and the way the facade meets the street. The goal is not to decide whether the contrast is beautiful. It is to recognize that difference can be intentional and tied to a different cultural function.
Connect architecture and performance
Laterna Magika is a useful clue because multimedia theatre already combines forms that are usually kept separate. Carry that idea back to the building. Ask how circulation, public foyers and visual surfaces might support a theatre conceived around mixed media. You do not need a technical plan to make the connection. The official source gives you enough to read the New Stage as an architectural partner to an experimental performance institution, not as an isolated modern object.
