Basic understanding of construction in height and width

Explanations about the limits of construction and its basic principles until the safety margin is exhausted, depending on the material used.

Structural integrity is the mechanic that dictates how high or far you can build with each building type. Different building types have different levels of structural integrity. The table below outlines values for each building type. Durability is a building type's HP. Height and Length are how many pieces can be placed vertically and horizontally without additional support. Their reinforced versions are how many pieces can be placed with the addition of beams.

Note: This is not the maximum height and length you can achieve with these types, but rather, the height and length that can be acheived by using the first piece as the only anchor point to the ground. For example, you could build Thatch higher than 5 if you also connect the second, third etc piece to the ground with diagonal beams, though even this method has its height limits. Another thing to note is that while these numbers tell you how high and far you can build, it does not take into consideration the weight capacity of the pieces. For example, if you build 5 Wood floors next to each other that are only supported at a single point on the first piece, and try to place a heavy deployable on the 5th piece, it is likely to break.

I just tired to d a simple mission to build a tower for a beacon. The tower needed to be five stories high.

I tried first to build a square tower with no supports out of wood, basically making square rooms one on top of the other. By the third level, it began to break, then fell apart down to the first level.

After some thought, I then tried a square, four space room for each floor. I added in both vertical and horizontal supports, though no diagonal ones. First floor was fine. Second floor actually creaked quite a bit, but then settled. Third floor was also fine; I think due to the fact that I put in all the supports first, then the walls. The fourth floor was creaky and didn't seem stable. The fifth floor refused to stay up long enough to be completed; neither the support framework nor the walls would stay solid long enough for me to do anything other than snatch them back before they collapsed.

I'm not sure what aspect of this I'm missing. Maybe it's the diagonal supports? But the highest I was able to get with wood was four levels, and a shaky fourth at that. Five was out of the question.

I saw that you were already answered in another topic, but I will write here too. As soon as you want to build something 4-5 floors or higher, it needs to be placed on stone beams (https://icarus.fandom.com/wiki/Stone_Beam), and if noticeably higher, then on concrete beams (https:// /icarus.fandom.com/wiki/Concrete_Beam) installed at the very bottom of the earth.
Walls, floors, and inclined structures (stone, wood or concrete) themselves are not ‘load-bearing’ structures.
‘Load-bearing’ structures are only beams and foundations (stone, concrete)

Below is an example of my 'castle' in section (there are either 9 or 10 floors - I don’t remember exactly). Now the concrete roof is all green.
Vertical ‘pins’ are concrete beams that go all the way to the ground, otherwise the safety margin for the side towers standing on stone foundations has become insufficient. But concrete foundations were expensive and did not fit the style.
