Belgrade

Hello, everyone. A parliamentary election wiil be held in Serbia in about twenty days. The President of Serbia and the President of the largest Serbian Progressive Party posted a promotional video on YT in which a girl plays with Lego Modular Buildings in her room. Could anyone who knows here write which Lego constructors were used in this video (official names) and what is their price? Or, what is the approximate value of the whole room? All details are welcome. Thanks a lot in advance.
