Partial destruction that is mostly done in reconstruction can have different dimensions; Demolition of floor and wall for plumbing and installations, replacement of ceramic tiles, etc. or opening up the space. Because usually in the old plans, most of the houses were made of many rooms and the spaces were mostly enclosed and closed, today's interior design wants to have spaces with an open and free plan, so the walls can be removed or moved. Of course, this issue requires expertise, why?

There are two types of walls in every building; Carrier and non-carrier. Bearing walls bear the weight of the roof and floors and transfer it to the foundation, so their destruction can lead to the collapse of the building. All the external walls of the building and some internal walls are load-bearing. So, if you are going to destroy the load-bearing wall, you must first build support for these walls with the help of structural calculations and an expert; Horizontal beams and vertical columns. Demolition of non-bearing walls is less troublesome because they do not play an important role in the structure. You can easily destroy them within one or two hours with a sledgehammer, etc., but there is a point that you must specify the walls and parts you want to destroy before destroying them in order to prevent additional destruction. Remember that there are usually wiring and pipes in these walls and they should not be damaged during demolition.
