First, when it comes to home improvement, the flooring should be carefully considered. Not all floors need to be covered with marble. Marble is significantly more expensive than tiles or wooden flooring. Using marble on the floor can make the space feel overly heavy and unbalanced. Especially on the second floor or higher, the weight of the flooring materials should not exceed 40 kg/m², as the house hasn’t been officially evaluated for structural safety.
Second, during living room renovation, avoid drilling into load-bearing walls or removing walls that connect the balcony to doors and windows. Expanding existing doorways or adding new ones can lead to cracks in the building structure and weaken its seismic resistance, which may reduce the overall lifespan of the house.
Third, when decorating the balcony and bathroom, choose lightweight materials. Overloading the balcony can lead to structural instability or even collapse, so it's important to keep the weight under control.
Fourth, waterproofing in the bathroom is a crucial step. A common practice is to block the drain and fill the area with at least 5 cm of water before tiling. If any leakage occurs, re-waterproofing is necessary. If no leaks are found, proceed with careful tile installation while avoiding damage to the waterproof layer or tampering with plumbing and heating systems.
Fifth, in living room decoration, it's tempting to go for a luxurious look by covering all four walls with panels and installing multi-layered ceilings. However, this approach is not advisable. It takes up valuable space, increases costs, and can be a fire hazard. Too low a ceiling can also create a cramped and uncomfortable atmosphere.
Sixth, when selecting electrical wiring, always use copper wire instead of aluminum. Aluminum has poor conductivity, which can cause overheating, loose connections, and even fires. Additionally, wires should never be directly embedded in walls—always install them in proper conduits to prevent electrical hazards.
Seventh, during construction, avoid making holes or installing suspended ceilings and decorative lighting fixtures on concrete slabs with circular openings. These structures can compromise the integrity of the building’s framework.
Eighth, ensure that gas pipelines and equipment are properly maintained during indoor decoration. Do not remove or alter gas lines, as this can disrupt the system’s normal operation. Also, maintain a minimum horizontal clearance of 10 cm between power lines and gas pipes, and at least 3 cm if they cross each other.
Ninth, avoid placing the gas stove on a wooden cabinet in the kitchen, and never enclose the main gas valve inside one. In case of a fire, it could become impossible to shut off the gas, leading to potentially catastrophic consequences.
