"Az új épületen sok nagy ablak van."

Translation: There are many big windows on the new building.

[cymbidy]

It's more natural to say there are windows "in" the building than "on" the building, no?

[Judit294350]

Agree. "On" suggests they is not part of the building. Maybe someone has stacked up a pile of windows on the roof or something. I've reported it.

Depending on the context, both "in the building" and "on the building" would be natural in English.

[Yet1970]

Large windows is jó ... nem csak big windows

[GGKiss2]

Ugyanez a problémám nekem is.

This sentence is a bit ridiculous ...
