The wind resistance coefficient of the required design scheme and design parameters will inevitably destroy the existing building level and the original waterproof structure of the terrace. If you really want to do it, you should go to the urban management department for the record to prevent it from being treated as illegal construction.
First draw the drawings, and then you must go to the building authority where the house is located to declare the building, and after it is approved by the building authority.
Second, the construction of this damaged structure can only be carried out through declaration and fire safety design.
Third, then go to the property to go through the construction procedures, and the steel structure needs to be fixed on the floor.
It is illegal to build a sun room without authorization, whether it is a steel structure or a brick-concrete structure, which will inevitably destroy the existing architectural level of the terrace. Moreover, it is necessary to make a fixed connection on the floor to make a steel structure, which will inevitably destroy the original waterproof structure. The construction of this damaged structure can only be carried out through declaration.
You should consult the urban management department, fill out an application form first, and then you can start building your own sunshine room after it is approved. When making a sun room, you will inevitably destroy the original waterproof structure of the building, so you must pay attention to another important point, that is, the sun room is waterproof.

Matters needing attention in building photovoltaic sun room:
1. If the housing area is large, especially villa buildings, the sun room is mainly used for leisure, fitness and flower cultivation. In winter, it is advisable to choose a whole movable sun room and a movable roof. This kind of sun room will not have the problems of poor lighting in the sun room with insulation board and high indoor temperature in the sun room with fixed lighting roof in summer.
2. If it is because of the small housing area, in order to expand the living space, the leisure sun room built requires high privacy and low economic level, and insulation board roofs, plastic steel doors and windows and insulation walls can be selected as peripheral maintenance products. Although this kind of product is not a sun room in the strict sense, it is cheap, economical and practical. The disadvantage is poor lighting and general ventilation. If we add a skylight, it will be greatly improved.
3. If the construction of sunshine is mainly based on planting flowers and grass in winter, it is required that the sun room is well ventilated and the sunshine is appropriate. Plastic steel windows, glass roofs and large skylight sun rooms should be used for peripheral maintenance. The price of this kind of sun room is low, but the indoor temperature is high in summer, so it needs to be equipped with sunshade.
4. If it is a sun room that needs traditional architectural functions (such as a distinctive living room, study room, activity room, etc.). ), it is advisable to choose tempered insulating glass roof, with proper amount of special insulating glass skylight, broken aluminum insulating glass window or aluminum-wood composite insulating glass window as peripheral maintenance products. When in use, it needs to be equipped with special sunshade, sunshade, invisible screen window and other products.
