Hello everyone,

I have a question about something I don’t fully understand and would appreciate your help!

How should the window size specified in the construction drawing be correctly interpreted?

The dado height (brüstungshöhe) refers to the height up to the edge of the wall. So, a dado height of 1.00 m (3 feet 3 inches) corresponds to four rows of bricks, correct?

The size of the wall opening for the window is shown on the construction drawing, for example, as a width of 1.635 m (5 feet 4.5 inches) and a height of 1.46 m (4 feet 9.5 inches).

So the bricklayer will leave me a hole in the wall of 1.635 x 1.46 m (5 feet 4.5 inches x 4 feet 9.5 inches) after completing their work, right?

However, if I plan to install an external roller shutter box with a height of 30 cm (12 inches) above the window, then I actually need a wall opening of 1.635 x 1.76 m (5 feet 4.5 inches x 5 feet 9.5 inches).
Does this also need to be specified in the drawing?
Is it enough to add a note like “Attention: roller shutter box” and then all the experts will understand the requirement?
Or is it supposed to be understood differently?

In the end, I want to have the correct wall opening so that I don’t end up without roller shutters.

Thanks in advance to everyone!

How should the window size be correctly interpreted in the building plans?

The specification for the sill height refers to the height up to the wall edge. So, a sill height of 1.00 m (3.3 feet) corresponds to four rows of bricks, right?

The dimensions of the window opening in the building plan are given, for example, as 1.635 m (5.36 feet) wide and 1.46 m (4.79 feet) high.

So after the mason finishes, I should have a hole in the wall that measures 1.635 x 1.46 m (5.36 x 4.79 feet), is that correct?

But if I’m planning to install an external roller shutter box on my windows with a height of 30 cm (12 inches), I would actually need a wall opening of 1.635 x 1.76 m (5.36 x 5.77 feet).

Does this also need to be specified in the plans?

Ultimately, I want to have the correct wall opening so I don’t end up without roller shutters.

I really like that you are dealing with the topic in such detail and asking the right questions—and then drawing the right conclusions afterwards.

The highlight was last week in another thread when someone wanted to determine the sill height down to the millimeter/centimeter.
