Reading a drawing - height information?

But the kitchen is supposed to be 91 cm high. I think I have to make a call tomorrow.

86 cm parapet height and on top of that, with some padding, the worktop results in a working height of 91 cm. What you need to clarify is whether the window frame has at least about 6 cm in height. This allows 5 cm to be used for padding and the worktop.

In our plans, for example, there was a parapet height of 1m (4 rows of bricks) and later this became a finished height of 90cm, screed and underfloor heating were about 15cm, and the windowsill and plaster/mortar underneath were about 5cm. The plans were used by the bricklayers on site for building.

Best regards
