I would like to move the partition to make the living room smaller and make the bathroom larger, and

Generally speaking, when the load-bearing wall is a brick wall, the structure thickness is 24cm, the thickness of the external wall structure in cold areas is 37cm, and the wall thickness you want to move is 30cm, it must be a load-bearing wall, and such a wall can not be moved casually, according to the relevant provisions of the current "Residential Interior Decoration Management Measures".

Article 5 The following acts are prohibited in residential interior decoration activities:

A) without the original design unit or the design unit with the corresponding qualification level to put forward the design plan, change the main body of the building and load-bearing structure; ”。

The load-bearing wall can never be demolished and modified, because the load-bearing wall should carry all the weight of the building, change the bearing point, and the load it carries will be dispersed to other stress points, and the long-term overload will affect the bearing capacity of the building, so the wall can neither be moved nor thinned.

Sixth decorator engaged in residential interior decoration activities, without approval, shall not have the following acts:

1) Erection of buildings and structures;

2) Changing the façade of the dwelling, opening doors and windows on non-load-bearing exterior walls;

3) Demolition and alteration of heating pipes and facilities;

4) Demolition and modification of gas pipelines and facilities.

This kind of fenestration is to change the façade of the house, and even the non-load-bearing exterior wall is not allowed to open the window, and the load-bearing exterior wall is even more prohibited.

ARCHITECTURALLY SPEAKING, THE 480MM WALLS ARE LOAD-BEARING WALLS, AND THE 240MM WALLS ARE PARTITION WALLS, SO YOUR 300MM WALL MUST BE A PARTITION WALL, NO PROBLEM TO REMOVE, BUT IT IS A LITTLE DIFFICULT FOR YOU TO THIN THE PARTITION, THIS KIND OF WALL IS GENERALLY BUILT HORIZONTALLY WITH 85 BRICKS (THIS KIND OF PARTITION WALL CANNOT BE MADE OF LIGHT STEEL KEEL GYPSUM BOARD), PLUS THE CEMENT PLASTERING LAYER AND TILES ARE NOT MUCH THINNER THAN THE ORIGINAL, HEHE (MAY BE A LITTLE THINNER), SO YOU HAVE NO PROBLEM WITH DEMOLITION, AS FOR HOW THIN IT DEPENDS ON THE CRAFTSMANSHIP OF THE WORKERS, HEHE. And waterproofing must be done well (it is best to do the wall height of 1 meter), especially the corner of the wall, it is best to do a water storage test if the waterproof is intact.

Because it is a frame structure, the safety problem may not be too big, but it is better not to move, because architects consider the problem of weighing and stress when designing buildings, and the walls that are generally left are load-bearing walls, or structures that are useful for the overall building, so it is best not to change.

In the past, in addition to load-bearing walls, buildings would also leave some partition walls (non-load-bearing), but now most developers only leave weighing walls, generally without partitions, so that on the one hand, owners can partition according to their own style, and on the other hand, developers can save costs.

Yes, as long as it does not affect the structure of the building, it can be demolished, but when the bathroom is made, pay attention to waterproofing.

Yes... As long as your wall isn't used as a scaffold, it's okay to get old
