Did you know that there are certain areas in your home that should never be touched during renovation? These are known as "forbidden zones" — places that, if altered or removed, can compromise the structural integrity of your building and pose serious risks to you and your neighbors. Some areas may not seem important at first, but they play a critical role in the safety and stability of your home. It's always best to consult with professionals before making any changes. What Are the "Forbidden Zones" in Renovation? 1. Load-bearing walls: These walls support the weight of the structure above. In brick-concrete buildings, any wall that is more than 24 cm thick is typically load-bearing. You should never remove or drill into these walls without professional guidance. Even small modifications like opening a window on a load-bearing wall can weaken its strength and lead to dangerous consequences. 2. Steel reinforcement in walls: The steel bars embedded in concrete walls act like the skeleton of the building. Damaging them during plumbing or electrical installations can reduce the structural strength of the floor or wall, which could be especially dangerous in an earthquake. 3. Beams and columns: These are essential for supporting upper floors. Removing or altering them can cause the entire structure to collapse, so it's strictly off-limits unless done by licensed professionals. 4. Walls near the balcony: The wall between the room and the balcony is often called a "weight wall." If you remove this, it can significantly reduce the balcony’s load-bearing capacity, potentially leading to a dangerous situation. 5. Doors with reinforced frames: Doors that are built into the concrete, such as those in fire-rated or security doors, should not be removed or modified. Doing so can damage the building structure and make it difficult or even impossible to reinstall the door properly. 6. Waterproof layers in bathrooms and kitchens: These layers protect against water damage below. If damaged, it can result in leaks and flooding. When replacing flooring, be careful not to cut through the waterproofing layer. If it's damaged, a 24-hour water test must be conducted to ensure no leaks occur. Other Sensitive Areas to Be Cautious About 1. Old-style toilets: Replacing a squat toilet with a modern one involves changing the sewer system, which requires careful planning and can affect the existing waterproof layer. Improper installation may lead to leaks or improper drainage. 2. Gas and heating pipes: These should only be handled by certified professionals. Any unauthorized modifications can lead to gas leaks or heating inefficiencies. Never cover meters or tamper with pipelines yourself. 3. Original steel windows: While many people replace old steel windows with aluminum ones, some cheaper options may not be as strong. This can lead to issues, especially in high-rise buildings where window durability is crucial. Materials That Should Not Be Used in Renovation 1. Avoid harmful materials: Some decorative products contain chemicals that can be harmful to your health. Whenever possible, choose natural and non-toxic materials. After renovation, make sure to ventilate your home for at least a week. 2. Limit the use of thick stone: According to building regulations, natural stone thicker than 1 cm cannot be used in residential decoration due to weight and structural concerns. Understanding these key areas and materials will help you avoid costly mistakes and ensure your home remains safe and functional. Always work with experienced professionals when planning any major renovation. Your safety and peace of mind are worth the extra effort.
