ᐅ New Construction: Crack in Exterior Plaster (KFW 55 House)

Hello everyone,

we are currently building our house. Over the weekend, we noticed a crack in the exterior plaster. The crack is about 20 - 30 cm long (8 - 12 inches). It runs vertically.
Is this normal? Or should I be concerned?

Best regards

Take a photo (please hold a measuring tape or ruler next to it) and measure the crack width and depth (insert a thin nail).

What type of wall structure is it? How long has the plaster been applied?
