It means your brickwork has been completed! *happy dance*

Plate height in construction is reached when your walls are standing at full height and the rooms in your new home are really taking shape. King bed? On the wall facing the morning sun. Desk? Left side office wall with the perfect space for the vision board above it. You’ll start seeing everything now. 

Your roof timber and steel materials will be delivered next, and a roof carpenter will arrive on site to build the structure. Happy, happy days!
