Is it possible to identify the wasp species/family by the nest?
Ok, my bad. Should've googled better.
It seems that it might be a common wasp aka Vespula vulgaris. It's said that the colour of the nest is caused by material being collected from the rotten tree trunks.

See the identified sample:



It's said that they don't make nests in houses too often that's why I'm not accustomed to the look of the nest.
