There will be problems arising when members of a family are increasing and want to expand the house building, of course there is no more land left. One solution is to build 2-storey or more terraced houses. When you build a house with a design of 2 floors or more, then as a connecting floor to one another it is a staircase. When we have known the plan of our house that we will install the stairs, then this will be enough to make it easier for us to choose various designs of stairs that are suitable for the house. It also aims to simplify the process.
The design of the ladder should have been adjusted to the design of the house without ignoring the comfort and safety factors. When the design of the ladder is felt good and comfortable, then we who stand it will be able to move comfortably.
Here are some level ladder designs, hopefully they can be useful.
