You might not be aware, but there are several "forbidden zones" in your home that should never be altered during a renovation. These areas are critical to the structural integrity of the building and tampering with them can lead to serious safety risks—not just for you, but also for those around you. In addition to these forbidden zones, there are also "sensitive areas" where changes should be avoided unless done by professionals. Forbidden Zones During Renovation 1. Load-bearing walls: These walls are essential for supporting the structure of your home. Many people know they shouldn’t be removed, but not everyone understands how to identify them. In brick-and-concrete buildings, any wall made of prefabricated slabs or over 24 cm thick is typically load-bearing and cannot be altered. Walls that sound hollow when tapped are likely non-load-bearing and safe to remove. However, opening doors or windows on a load-bearing wall can still cause damage and is not allowed. 2. Steel reinforcement in walls: If your home has reinforced concrete structures, the steel bars embedded in the walls act like the skeleton of the building. Damaging them while installing pipes or making changes can weaken the structure, potentially leading to collapse during an earthquake or other stress. 3. Beams and columns: These are crucial for supporting upper floors. Moving or altering them can result in catastrophic consequences, such as the floor above collapsing. 4. The low wall next to the balcony: This wall, located between the room and the balcony, plays a key role in supporting the balcony’s weight. Removing it can reduce the balcony's load capacity and even cause it to fall. 5. Doors with "three defenses" or "five defenses": These are reinforced door frames that are embedded in concrete. Any modification could compromise the building’s structure and make it difficult to reinstall a new door later. 6. Waterproof layers in bathrooms and kitchens: These layers prevent water from seeping into lower floors. Damaging them can turn your neighbor’s apartment into a flood zone. When replacing flooring, always be careful not to damage this layer. If it is damaged, a 24-hour water test must be conducted to ensure no leaks occur. Sensitive Areas in Your Home 1. Toilets in bathrooms: If you're upgrading from a squat toilet to a modern one, be cautious. This involves changing the sewer system, which can be complex and may require breaking the waterproof layer. Improper installation can lead to leaks or improper flushing. 2. Heating and gas pipelines: Only licensed professionals from the gas company should handle these systems. No one else should attempt to modify or cover gas meters, water meters, or electricity meters. Similarly, heating pipes should not be moved without expert advice, as it can affect the heating efficiency of your home. 3. Original steel windows: Some homeowners replace old steel windows with aluminum ones. However, some cheaper aluminum options are less durable and may not hold up well, especially on high-rise buildings, risking detachment and safety issues. Materials That Should Not Be Used in Renovation 1. Avoid using harmful materials: Some decorative materials contain chemicals that can be harmful to your health. It's best to choose natural materials whenever possible. After renovation, open windows for at least a week to allow any fumes to dissipate. 2. Do not use overly thick stone: According to current regulations, natural stone thicker than 1 cm is not permitted in residential decoration due to its weight and potential instability. These are just a few of the areas you should be cautious about during renovation. Always consult with a professional before making any major changes. Ensuring safety during the process is essential, not only for yourself but for everyone living around you.
