A Guide to HDB Bomb Shelters: Renovation Rules, Maintenance, and Design Tips

Since 1996, all HDB flats in Singapore have been required to include a Household Shelter, commonly referred to as a bomb shelter. Designed with reinforced walls, floors, and ceilings, these shelters provide residents with a safe space in the event of an emergency. If you’re planning to renovate your home, understanding the restrictions and possibilities around your household shelter is crucial. Here’s what you need to know.

Household shelters are built to protect residents during emergencies. Their reinforced structures ensure stability and resistance against external impacts. These shelters are marked clearly on HDB floor plans with thick black lines, typically located near the living or dining area, or close to the kitchen.

To maintain the structural integrity of the shelter, the Housing & Development Board (HDB) imposes strict regulations on modifications. Homeowners are not allowed to:

• Hack or drill into the walls, floors, or ceilings of the shelter.
• Remove or replace the original bomb shelter door.
• Tamper with the ventilation sleeve or any other components.

However, certain modifications are allowed, such as:

• Applying decals or paint to the shelter door for aesthetic purposes.
• Installing removable shelving units inside for storage.
• Concealing the shelter within built-in cabinetry, as long as the door remains accessible.

Many homeowners use the shelter as a storeroom, but it’s important to ensure it remains functional in emergencies. Here are some tips:

• Avoid overcrowding: Overfilling the shelter can make it difficult to access in an emergency.
• Check the ventilation sleeve regularly: This round metallic disc on the door ensures proper airflow and can be tightened when necessary.
• Ensure the door remains intact: Do not alter or obstruct the locking mechanism or rubber gasket, as these are essential for maintaining an airtight seal.

Although the shelter’s door and structure cannot be removed, homeowners can make design adjustments to blend it seamlessly into their home decor. Here are some creative ways to do so:

• Use wall decals or paint: Applying wallpaper, vinyl stickers, or a fresh coat of paint can make the shelter door less obtrusive.
• Convert it into a display board: The steel door is magnetic, making it ideal for sticking notes, artwork, or even magnets from your travels.
• Hide it within built-in carpentry: Custom cabinetry can be designed to cover the door without obstructing access.

HDB bomb shelters are a necessary safety feature, but that doesn’t mean they have to be an eyesore in your home. By following HDB’s renovation guidelines and incorporating creative design solutions, you can make your household shelter both functional and visually appealing. Whether you use it for storage, emergency preparedness, or as part of your home’s decor, understanding its purpose and limitations will help you make the most of this essential space.
