Hello everyone,
Now that our house construction is finished, we want to build a bit of a terrace.
It should be somewhat larger (about 6 meters (20 feet) from the house), and according to our wood expert for the terrace roof, we should pour concrete footings at the four corners. That makes sense so far.
Now my question is how to best ensure the horizontal level for the footings. Unfortunately, I don’t have a long spirit level or straight board to measure with.
My reference height is at the edge of the house where footing No. 1 will be. How can I transfer the exact same height 6 meters (20 feet) further away?
Thanks in advance for your suggestions.
(I’m somewhat familiar with a water level hose, but I don’t really know how it works and I don’t have one either.)

A water level is very simple and accurate; you can even make one yourself if needed. A garden hose, two transparent funnels/end pieces, tape – that's all you need.
However, make sure your terrace has a slope, otherwise water will collect on it. A perfectly flat and level surface is exactly what you definitely do not want.

There are always some experts with laser pointers.
Mine is only laser class 2. It was always explained like this:
The accessible laser radiation is only within the visible spectrum (400 nm to 700 nm). It is approximately safe for the eyes during short exposure times (up to 0.25 seconds).
Note on laser classes 2 and 2M: A scientific study showed that the blink reflex (which occurs within 0.25 seconds; longer exposure damages the eye) was present in less than 20% of test subjects. According to the study, the presence of the blink reflex should not be assumed as a general protective mechanism for the eyes.
This should not be underestimated.
