At present, there are common red brick walls (masonry walls with the thinnest thickness 150MM are generally around 2 10-280MM), light steel keel+gypsum board partition walls (infilled walls with the thinnest thickness 100MM) and light brick walls (the dimensions are the same as above). Please note that the above dimensions are the thickness after plastering. The firmness is definitely the strongest and most stable red brick wall, and the sound insulation effect is better if it is double-layer hollow. However, due to some practical considerations (mentioned below), the latter two are often used the most.

I don't know what floor your shop is on, and I don't know how wide the wall you want to partition is. Shops are generally high (close to or over 3m), so if the first floor is on the floor, there is no need to consider the bearing problem. If it is upstairs, the partition wall should be on the lower beam, and the wall should be reinforced from beginning to end, with a thickness of 240MM (provided that the wall width is below 5m). If you can't get the position of the beam, it is recommended to do120 mm. If you choose to pay attention to the sound insulation effect, it is recommended to use light steel keel wall with sound insulation cotton, benzene board or shale hollow brick (but the construction quality requirements are relatively high).

In addition, since it is a shop, safety is definitely the first consideration. If it is beyond the reasonable range, even if you have more ideas and requirements, it will be empty. There is no perfect thing in the world, so we should proceed from reality and try our best to solve it together with the property negotiation.

The problem of selling milk tea in your cubicle is actually very simple. If half of them are engaged in food-related businesses, such as non-staple food, cakes, fruits, etc., they can be merged (at most, they can be added) and have at most one catering service license (if seats are set); If it is not a food-related business, it is equivalent to adding a business entity, and the business license must always be handled. In addition, it is necessary to go through the formalities of health permit, individual industrial and commercial registration, fire protection and environmental protection.

In fact, tea shops don't need seats. You can try to add items to your business scope (depending on the nature and scope of your business), as long as you get a food circulation license (that is, a license to sell snacks and drinks), and then leave a small area for your wife to do tea business without zoning.
