Hello,
Every planner will start with an assumed height "0 - upper edge of finished floor" above sea level and from there consider the eaves and ridge heights. There are also development plans that do not regard the upper edge of the finished floor as a reference measure, but another measure; however, explaining this goes too far here.
Assuming your plot is on average at 55.00 and the adjacent street at an average of 55.50 above sea level. Then it makes more than sense not only to adapt to the street level but also to plan at least one more stair step higher so that a heavy rain shower does not cause a small flood. Water should always flow away from the house and not toward it! After that, your house should be planned at approx. 55.70 above sea level. If the development plan now prescribes a single-story building with an eave height of, for example, 4.00 m, the missing 70 cm can already be annoying as they also affect the knee wall height. This also shifts the 2.00 m line in the attic inward.
Your architect, however – as it is not otherwise possible – starts from sea level "0" and now diligently plans your house. Based on the above example, with an assumed knee wall of 1.30 m for a single-story detached house. Let’s keep "imagining" and you like the planning – maybe just a few small details in the first draft. Then, at some point, the preliminary version of the site plan is available, and it says – considering the heights drawn in above sea level: Damn, the knee wall must be lowered! Thus, the submitted draft "can" be for the trash...
Since you consciously decided to build with an architect, it would therefore be important for him to know the existing terrain heights; to be able to have the preliminary site plan available.
On the other hand, I don’t understand what use it is to you if the current favorite presents a first draft, but you are not at all sure if you want to commission this architect. It costs in the worst case a few thousand euros if it turns out that the chemistry is just not right. Why don’t you have finished plans/reference houses shown to you on the basis of which you decide?
Rhenish regards
"the game with the heights depending on the often used reference level upper edge of finished floor ./. exploiting eaves and ridge heights"
What do you mean by that?
