Right so its a party wall made of plaster board with a 1 year old crack..
How about actually giving some real information.. your just just going to get silly short answers.. also there are paper bags folded on top there..
How about answering these:
Age of building (1930s, 1990s, 1700s?)
Type of property (bungalow, block of flats, supermarket)
Is the wall solid (brick/block, timber, metal stud)
Width of crack (1mm, 100mm)
Does the crack extend above/below the cabnet
Whats above the crack upstairs (hot tub, safe, bath)
Does you neighbour have a crack in same spot their side
Are you founded on clay, chalk, sand, limestone, granite, peat, aluvium, gravels etc..
Recent building works (new extension, new drains, burst water pipe)
