Modular floor



How to create universal modules for an apartment building? So that with a minimum number of modules there was a maximum number of variants of apartment layouts. This problem is very urgent now. The solution to this problem will allow building efficiently and quickly. There may be many solutions to this issue. A good material for solving this problem are wooden structures. Since the tree is very light and environmentally friendly. I propose one of the options for solving modules for the construction of multi-apartment houses. The idea is to divide the floor of a apartment building into individual components (modules). Such components can be manufactured at the factory. Then quickly assemble the floor of the apartment house from these components. Two main modules are created: module 1 and module 2. Plus two additional modules: module 3 (staircase), module 4 (staircase with elevator). And plus module 5 (corridor overlap). Ready-made modules are brought to the construction site where the floors of the apartment building are collected from them. You can use modules for both the construction of new apartment buildings and for the superstructure on top of existing houses. Modules are manufactured from Kerto LVL products with thickness 51mm, 57mm, 75mm. Structural base - columns, beams and overlapping. From the modules you can collect different versions of floors. Modules are manufactured at the factory and ready to be brought to the construction site. At the construction site the modules are joined together by means of connecting parts. Where there are spaces without walls and overlapping additional walls and overlapping are added at the construction site. Also additional walls and overlapping can be added at the factory. Holes for engineering communications and ventilation shafts are made in modules according to the planning solutions of apartments. Module 1, module 2, module 3, module 4 do not change. Only the module 5 changes, depending on the length of the corridor and the docking of other modules. Fastening of modules to each other can occur in various ways: with the help of connecting metallic elements; with the help of protruding structural elements; with the help of special adhesives.

Key benefit

The modules for the floor have the following advantages: can quickly and efficiently build apartment buildings; easy to manufacture; have a light weight since they are made of wood; green technologies; allow you to create many variants of houses and floor

Ecological values



  • Economical span (mm)
  • Thickness (mm)
  • Airbourne sound reduction factor (dB)
  • Impact sound transmission (dB)
  • Resistance to fire class
  • Thermal properties


  • This modular system is really interesting. It has a lot of details that are not visible at first glance. A detailed look on each page is necessary to appreciate what it is. I wonder though how the sound transfer between floors can be overcome, as it looks like the floor and ceiling of each level have to be combined into one structural element. Between flats of the same level, it is simpler, as there are separate modules for each flat.
