In this episode, I have explained the improvement we are doing in the construction process.  

In order to increase efficiency and accuracy, most of our main contractor are adopting system form works during the casting process for structural members in a high rise project. And this is the main reason why we cannot hack walls in an apartment.  

The entire structural system of a highrise is connected, and to remove one of two walls is extremely dangerous. As if we are playing Jenga. Hence, there is a process of getting management's approval for any renovation work because it involves the safety of the building.  Thus, it's more practical to look for a layout that you actually like instead of getting an apartment and hack walls inside them.
