How Much Does It Cost To Build A Bunker

A bunker is a defensive military installation, built to protect soldiers and equipment from enemy fire. The term “bunker” originates from a Scots word for “bench”. But during the American Civil War, it began to be used to refer to a dugout or a trench.

A bunker is a fortified structure, typically in the form of a small building or room, that is intended to protect people or valued materials from falling debris, hostile action, and other dangers of the outside world. Bunkers are often inhabited by military personnel during combat operations. They are built with heavy masonry walls and thick metal roofs to protect them against the effects of artillery and bombs. The walls may be reinforced with concrete, brick, or other materials that provide protection from ballistic weapons.

Bunkers have been used in warfare since ancient times. In ancient China, they were often made by digging trenches in the ground and covering them with wooden or grass roofs. In the Middle Ages, they were often covered with dirt and used to store food or supplies, but they could also be used as defensive structures. In World War I and II, bunkers were used extensively as machine gun posts or command posts by both sides of the battle line.

A bunker is a defensive structure built to protect people and equipment in the event of a military attack.

The most common type of bunker is an underground structure that can be buried, hidden, or disguised. These are typically made from thick concrete, which stops bullets and other projectiles from penetrating the walls.

Bunkers can also be above ground, with concrete walls to protect against artillery shelling or aerial bombing. A bunker built into a hillside, for example, will be protected against bombs dropped from above by the surrounding earth.

When most people think of a bunker, they imagine the kind used for military purposes. These are typically built underground to protect soldiers from artillery fire and other dangers. However, a bunker can also be built for shelter in the event of an emergency, or as a way to live more naturally and off-grid.

As far as construction goes, you have two options: build it yourself or hire someone else to do it for you. The former may take time but is certainly cheaper than hiring professionals; on average, an experienced builder will charge about $5 per square foot of finished space (including labor). On top of that cost is material cost, the price varies depending on what type(s) of materials you want to use and whether or not they’re recycled/reclaimed materials (you don’t want your bunker collapsing after all). You’ll also need things like shovels and hammers, and maybe even cement mixers if they’re available locally, to complete your project successfully.

The average person imagines building a bunker as an expensive and complicated process. In reality, it’s not that difficult.  The main components of a bunker are the same as those used in any house or office building: concrete walls, roofing material, doors, and windows. The only difference is that these materials are installed underground so that they’re hidden from view by dirt or sand.

Size of the Bunker

The size of your bunker is one of the most important factors to consider. The size of your bunker will help determine how many people can fit inside, what kind of equipment you can fit in it, and how much food and water you need to store.

The most common bunker sizes are:

  • Small (4×4 feet) – This is a small personal shelter that can hold up to one person. It’s great for use as an emergency getaway or hiding place in case of an invasion or zombie attack.
  • Medium (8×8 feet) – A medium-sized bunker holds up to eight people comfortably and has plenty of space for supplies, equipment, food storage, and more.

Location of the Bunker

The next thing you need to consider is the location of your bunker. While it may seem like a no-brainer, your bunker’s location is critical to its success. You must think about both the above-ground and below-ground aspects of this decision.

Above Ground

As far as the above ground goes, there are many things that you will want to consider in terms of how much security and privacy you can get from each choice. For example:

  • How far away from natural disasters do I want my bunker? It would be smart to select a site that is not near any major rivers or fault lines if possible. These areas tend to be prone to weather extremes so you want somewhere not at risk for flooding or earthquakes/tsunamis/etc…
  • Do I want my bunker located in an area with lots of trees or one where there are mainly plains? The answer here depends on whether or not trees make it harder or easier for people who don’t have permission into your property (which could happen because someone wants what’s inside). If trees make it harder then maybe pick something else; otherwise go ahead.

Bunker Walls and Roofing

The walls and roof of your bunker are the most important aspect to consider. While you may be tempted to skimp on these materials, a strong bunker will save you money in the long run. The most common material used for bunker walls is concrete, and it’s easy to understand why: Concrete is durable and inexpensive, but it can also be built in any shape or size depending on your needs. A good rule of thumb when building bunker walls is that they should be at least two feet thick, but three feet would provide even more protection against blast forces and other hazards associated with nuclear explosions.

Bunker roofs are typically made from reinforced concrete or steel (or both), because they need both strength and durability in order to survive an attack by ICBMs or nuclear bombs. In some cases, though not all, it depends on where you live, the roof will be domed or arched so as not to block out too much natural light from entering into the structure below ground level; this can help keep morale high among residents who might otherwise feel claustrophobic after spending long periods of time inside their underground shelters.

Air Filtration System

It is important to have an air filtration system in your bunker. The quality of air inside the bunker will determine how healthy it is for you and your family. You don’t want to breathe in dust, mold, bacteria, spores, and other airborne contaminants that can be extremely harmful to you or your loved ones.

You also have to think about the chemicals that might be outside of the bunker during a disaster or crisis event. If gas leaks are happening all around you, then there’s a chance that it could get into your home through cracks in doors and windows or even through vents in the wall if they aren’t sealed tight enough. Your air filtration system has to be able to filter out everything (including dust particles) so that no harmful substances can enter your shelter.


Lighting is one of the most important factors when designing your bunker. It is vital for safety, to provide a sense of security, and to keep you awake during long periods of darkness. You will need lights for both natural light and artificial light, depending on your location and preference. Solar-powered or battery-powered lights are ideal because they will work in any environment and do not require an external power supply as electricity does. A low-wattage bulb is sufficient for general use throughout most parts of your bunker, but if you want more light or require an area to be illuminated brightly then a high-wattage bulb may be required. Natural light can also be used as an alternative source of illumination by using skylights in areas where there is access to sunlight such as windows or ventilation shafts that have been opened up into the surface above ground level outside your bunker location.

Stocking Your Survival Bunker

The next step is to stock your survival bunker with food and water. You can make it last a few months on your own, but eventually, you will want to get out and start the rebuild process. If you can’t grow or hunt for your food, you are going to have a hard time staying alive in this new world so make sure that you have plenty of MREs (meals ready-to-eat), bottled water, and freeze-dried foods on hand.

You should also invest in some medical supplies as well as guns, ammunition, and tools for security purposes. You may also want to consider purchasing some clothing so that you are not forced into wearing old clothes all day long just because those are all that is available now when everyone else has access again too.

How long does it take Build A Bunker?

The time it will take to complete a bunker project depends on the size, complexity, and customization of your bunker. The longer you want to wait, the more expensive it will be.

Some people choose to build their own bunker, while others prefer to use an experienced contractor who knows what they’re doing.

Building an underground bunker can be expensive but it is worth it in many situations.

It’s important to note that once you’ve started building a bunker, you’ll want to continue working on it for as long as it is safe. If you stop before completion, then your bunker will be useless when SHTF. It may also be necessary for you to move into your own bunker when SHTF if there are dangerous situations happening nearby.

If you do not have an underground shelter or bunker yet and want one, then now is the best time to start building one because we are close to the end of time and things will only get worse from here on out.

There are different types of bunkers, and each one has its pros and cons. Some of them are easier to build while others require a lot of time and hard work. The best thing you can do is to decide what type works best for your situation.

Cost to build a bunker

The cost of a bunker can range anywhere from $35,000 to $75,000, depending on the size and luxury of your bunker.

For example, if you choose to build a large one on your property that can hold up to 20 people comfortably (such as in an underground mine), it may cost around $300 per square foot or more. If this is out of your price range, consider building a smaller bunker instead, a small shelter that will protect you from radiation but still allow airflow might only cost around $20,000.

In addition to the upfront construction costs for building bunkers, there are some ongoing expenses related to maintaining them over time: upgrading electronics; adding storage space, and keeping up with maintenance issues such as lighting repairs or plumbing issues due to aging pipes being buried underground without proper ventilation.

It costs $60,000 to build a 200-square-foot bunker, but it can range anywhere from $35,000 to $75,000. Larger bunkers, or bunkers with luxury upgrades like shooting ranges and swimming pools, can hit $9 million or more. Tiny mini shelters can cost as little as $20,000.

The cost of building a bunker depends on the size, location, and amenities you want. Bunkers can be built underground or in basements. They can also be built with a small budget or a large budget. In general, smaller bunkers tend to cost more than larger ones because they require more materials and labor to construct.

Bunkers are not just for survivalists. There are people who build them as homes or just as a way to escape from daily life for a few hours at least once in a while. Some people who want extra privacy may choose this option instead of renting an apartment; others simply like having their own space away from everything else around them but still within city limits so that they don’t feel too isolated from civilization if something goes wrong (like during an emergency).

If you’re considering building an underground bunker, there are many reasons why it can be worth the cost. Not only does it give you peace of mind about your family’s safety, but it also gives them a place to stay during emergencies. It may seem like an extravagant expense at first glance, but when compared with how much money it saves over time (and how much stress it relieves), building a survival bunker seems like a no-brainer.
