After searching for a very long time, I found the location of the country lane with Patricia, Mara, and Rufus Malpied from episode 27 of season 1 - part 1.
Thanks to the Facebook group, Cycling in the Netherlands & Belgium, Chris Bellekens recognized the area and came up with 3 places: Mechelen, Bonheiden, and Belgian Putte. Something told me it was Bonheiden, and that turned out to be correct.
Also thanks to the Facebook groups and with the help of the municipality of Bonheiden, she confirmed that it is indeed the location; everything matches as well: the electricity pylons on the right, the mailbox, and the lamp by the front door.
Unfortunately, only the barn on the left has been demolished, but the barn is indeed visible on old satellite photos from Geopunt.
The recordings took place on Uyerenboslaan in Bonheiden (Belgium).
Thanks to Chris Bellekens, Xander Stokkers, Bonheiden Facebook groups, and the municipality of Bonheiden.
