The signs use the Cyrillic alphabet, specifically "50% Есен/Зима", which points towards Bulgaria. The architecture and the style of the apartment blocks are very characteristic of Eastern European urban residential areas. The presence of snow and the general atmosphere suggest a cold climate in the Balkan region. I suspect this is in a city like Sofia or Plovdiv, Bulgaria. I am moderately sure about the country.

The sign clearly says "ГЛАВЕН ИЗПЪЛНИТЕЛ НА ОБЕКТА" and "БОКАЛ", which confirms Bulgaria. The ".bg" domain on the construction board further solidifies this. The "Bike Center" and the specific road signs are typical of a major Bulgarian city. I am now very confident this is in Sofia, likely in a developing residential district.
