The architecture of the building is functional and reminiscent of mid-20th-century Eastern European design. The presence of a calm, reflective body of water and the dense, deciduous trees suggest a park-like setting in a temperate climate. The lighting and foliage indicate an autumnal atmosphere in a northern latitude. Based on the style of the building and the overall landscape, I suspect this is in Russia or a nearby Baltic state. I am moderately sure this is in Saint Petersburg, Russia.

The presence of tram tracks embedded in the road is a strong indicator of a European city with an established public transit network. The blue road sign with a white arrow is typical of traffic regulations in countries like Latvia, Lithuania, or Estonia. The overhead wiring for the tram system and the specific style of the metal utility poles further point toward the Baltic region. The architecture and the park-like surroundings feel very consistent with Riga, Latvia. I am fairly confident in this location.
