Initial ideas for building a small house on a backlot

A development plan or the building regulations do not speak of floors, but of storeys

Okay, that would be the same for me as a layman now.

okay, thanks for the clarification. The houses around are all 3 stories, hence my confusion. so 150m2 = house plus garage plus garden shed?

Floor area ratio = buildable area = house + garage + garden shed + terrace etc. = 150 sqm It can, as I have written, be exceeded by ancillary facilities in floor area ratio 2 as well. PLEASE JUST READ THE ANSWERS LITERALLY AND DO NOT INTERPRET ANYTHING.

Okay, that would be the same for me as a layman now.

But it is not. That is exactly why you keep asking over and over again what you are allowed to build, without making an effort to understand it.

Why are so many people here so aggressive and rude?

1. KarstenausNrw I wrote exactly what you wrote in your answer. What is your problem?

2. ypg - what is your stupid answer supposed to mean? Someone had explained that it is no longer a full storey if the floor has fewer square meters than the lowest one. So what is your problem with my statement that for me as a layman, storey and floor were synonyms?

I thought people were supposed to be helped respectfully and politely here in the forum.

You can also build stepped floors if the development plan, for example, does not exclude flat roofs. And even with the high price per square meter, a small house can be a good investment.

It certainly would have been good to enter something like "Legend zoning plan" into a search engine before posting here. Then you would have already known that the I refers to the floors, and your initial repeated confusion with 500sqm of development, because you thought it was a floor area ratio, would not have persisted through the first pages here. Unfortunately, this comes across as if one decided to build 5 minutes before posting and partly causes it to seem like a fixated idea that the questioner will back away from anyway before an answer is even written... to put it bluntly.
