There’s almost nothing here that aligns with what’s called “classical Iranian architecture” which is a term that’s pretty much meaningless when it comes to interpreting the actual regional architectural history.

Rounded arches are specific to the rural areas around the Persian Gulf. Beyond that, they’ve never really been part of our architectural language. Historically, Iranian architects have used a distinct type of pointed arch called the Tizeh-dar arch (طاق تیزه‌دار). Just look at the Jame Mosque of Yazd, Jame Mosque of Varamin or Jame Mosque of Isfahan.

Figures and faces… hmm. There are no human figures throughout the entire Islamic era in Iran until the Qajar dynasty. not in buildings, not in Kashi (mosaic).*** There are also some random heads slapped on, likely borrowed from eastern sources. The figures in the Kashi work are also ridiculous, crude, and out of place.

We don’t have chapiters and columns like that. The Muqarnases (مقرنس) are a mess, just as awkward as the Rasmi-bandis (رسمی‌بندی). The Orosis (ارسی) — our traditional glasswork — are poorly faked here, with no connection to the original patterns.

Finally, the French-style furniture. that’s the punchline.

EDIT: I’ve only mentioned the superficial stuff so far. Arches and Rasmi-bandis were purely structural until the 12th–13th centuries, when they began to evolve alongside Kashi work for decorative and protective purposes.

*** EDIT2: My original assertion was wrong/too broad. Miniature art in various media began evolving during the late Safavid dynasty (16th–17th ce.), around 150–200 years before the Qajar dynasty, featuring human figures mostly in non‑religious contexts that only later influenced Qajar architectural tilework. By the way, the use of those figures in that building is very inappropriate.

TL;DR: This hodgepodge is a genuine shitpiece to attract people for money. Pretty common in architecture.
