It is crucial to plan on the exact points you are going to drill the holes in the room to anchor your gun safes. Remember to minimize the number of people, be it professionals or other people, who are involved in the preparation of your gun safe room blueprints so that you do not compromise its security.

How to build a gun safe room?

You can build a gun safe room in seven simple steps, they are.

Step 1: Pick a Location

Avoid picking a location that is frequently accessed by your family members. Pick a relatively discreet room so you can use it whenever you want. If possible, go for an area that is fire resistant. For example, a basement, closet, mechanical room, or any location with a concrete wall.


Step 2: Select a Vault Door

You’re building a gun safe; it needs as much security as possible. The door will be a pivotal point to determine the security level of your gun safe room. If you want to avoid unwanted visitors or unauthorized access in your gun safe room, go for a sturdy and difficult-to-break-through door.


Step 3: Think Before Deciding

Key elements when building a gun safe room

When constructing a gun safe room, it is paramount that you hire a reputable and trustworthy contractor. Due to the high value of items that are usually stored in a gun safe room, their construction details are prone to be leaked. No surprise there, most people tend to blabber and awe others with their latest jobs, etc.

It is also critical that you make use of durable materials that will be able to meet your security requirements. Having a prepared budget for the task will help you avoid inconvenience during the building process.



If you intend to have your gun safe room overground, you will have to turn one of your rooms into it. This option is easy. You will have to select a room that has no windows and start working on the inside walls, firstly providing additional support to them.

Most builders will prefer to buy prefabricated metal or concrete safe structures and drop them into the room, then construct regular stud-and-sheetrock walls around them so that the walk-in vault is consistent with your interior environment.

If you prefer doing it yourself, you can fortify a large closet. Closets are excellent because they usually have no windows and comprise dead space in the house.

However, due to the high-security stakes that are associated with gun safe rooms, it is recommended that you build the gun safe room in your basement. This option requires you to start from scratch. You will have to fortify the outside walls with rebars, cinder blocks, and Portland cement.

These materials will make it difficult to break into the room, even by the most determined intruder. The strength of your wall should be dependent upon the level of security you need.

If you are not financially prepared for a heavily fortified outside wall, you should consider working only on the inside. The inside of the wall is also paramount.

You can make use of pre-built wall panels that are customizable to accommodate the firearms properly. These are easily procured and installed. Furthermore, they help you to properly store multiple firearms inside a limited space.



The need for a secure door for your gun safe room is pivotal towards the overall security of the facility. The existence of a sturdy door for your gun safe room significantly reduces the chances of unauthorized entry or abuse of the facility. If security is your primary concern, you should go for a vault door.

Ensure that the support system is strong enough to hold it in place because a vault door has a lot of weight. Sometimes, people do not want to expose the vault door for aesthetic reasons or to simply avoid drawing attention to the safe. If that’s the case, you will have to add a normal door outside the vault door so that you match your household texture.

Your gun safe room door should have a high level of security. It should have a complicated locking mechanism that is difficult to even figure out, preferably one of those custom-made units with its own locking patterns and design. A keypad lock combined with a biometric locking system can also provide a great additional security layer.



Adequate ventilation in your gun safe room is critical to ensure that your guns and valuables are always in the correct environment.

The absence of an adequate ventilation system may cause your guns to be compromised by rust due to the temperature and humidity in the room. However, you have to be cautious about installing the ventilation system as it can breach security. It should not become the weakest link to the facility.

A gun safe room or vault is a distinctly secured room used to store, not only guns, but your other valuables such as art, precious metals, currency, important documents, and so on. In this article, we will go over everything you need to know about how to build a gun safe room.

Contrary to common belief, a gun safe room is capable of serving multiple purposes at once. It does not only provide excellently and managed storage space for your guns and valuables, but can also act as a robust home defense system where your family may retreat in an emergency. Think about it, where else would you rather be in times of trouble than in the one room where all your weaponry lies?

A gun safe room may be in the form of a collection of cabinets and glass carousels to store the weapon inventory of a gun shop, or it may be a small room that has wall panels designed for mounting weapons. These rooms are usually designed in the basement of a house so that they remain discreet, however, it’s entirely up to you.


Types of gun safe rooms

There are two types of gun safe rooms, namely the overground and the underground one. As obvious as their names may sound, let’s just take a closer look at each of these two.


1. Overground gun safe rooms

Overground gun safe rooms


As the name suggests, this one is built over the ground. Its advantage is that your safe spot will be easily accessible for your use and enjoyment. Furthermore, it is not prone to humid conditions like its underground counterpart.

Even though, you might still have to consider running a central air conditioning system into the room to ensure that your guns stay under constant environmental conditions that are desirable for long-term storage.

While your over-ground gun safe room should be built into your house at the time of construction using cinder block, stud construction, and rebar fortified walls, retrofitting is also possible. If done right, a walk-in gun safe room might end up being one of your favorite places in your home to hang out in and admire your ammunition.

The downside of an over-ground gun safe room is it can be easily accessed by intruders. Therefore, it is crucial to ensure that it is coupled with enhanced security systems.


2. Underground gun safe rooms

Underground gun safe rooms


Having this type of gun safe room often means it will be located in a basement. An underground gun safe room is the best option in terms of security considerations. It will keep your guns secure against fire outbreaks, hurricanes, or even burglaries.

Why these mishaps specifically? Well, each one may easily turn your gun safe room from being your source of protection to being your biggest threat!

The main downside of an underground gun safe room lies in the complexity of the building process. When building this type of gun safe room, requires serious professional consultation.

It is also vital to install a sump pump drainage system underground to ensure that water is drained away during floods. Again, it is advisable to make a separate power outlet if your gun safe room is built in the basement so that you can secure it in the case of a power outage.

Establishing an internet connection that is linked to security cameras will also enable you to monitor the room from above.

Another key issue that comes with locating a gun safe room in your basement is the humidity challenges. It can cause your guns to rust. It will be necessary to install a moisture barrier to keep humidity away. An inline vent fan is also pivotal in improving circulation in the room. Of course, all these extras will cost a bunch more!


Local gun storage laws

One of the most critical aspects involved in building a gun safe room is adherence to local gun storage laws. Gun storage laws vary from one jurisdiction to another. For instance, some local authorities have laws that require firearms owners to lock their guns in a safe and also stipulate a limit on the number of guns one can own.

Therefore it is paramount that you check and comply with your local gun storage laws in your area. You should also consider insurance policies in effect in your area. It is vital to ensure that your gun-safe room adheres to the insurance code of your building. Complying with all local gun storage laws will help you avoid being involved in legal disputes with the authorities.


How much does a gun safe room cost?

It is dependant on the room size. If it is small, you can expect to spend as much as $3000. But for larger rooms, the cost may exceed more than that.

The features you need will also contribute to the room’s overall cost. Getting a sturdy vault door itself will cost you around $1000.

You can get a gun safe if your budget does not allow building a gun safe room. But for maximum security of your weapons, it will be more practical to build a room.


Gun Safe Room vs. Gun Safe

Wondering whether a gun-safe room is worth the investment?

It depends on how many firearms you own. Gun safe rooms are a good choice for people who possess more than one weapon. Generally, their collection won’t fit securely in a gun safe.

For most people, however, gun safes are enough to store their firearms. The primary reason for this is they don’t possess the number of weapons to need a dedicated room for them.

Gun safe rooms are best for people who own multiple firearms that just won’t fit inside a safe. At times, gun safe rooms can be used as panic rooms or storm shelters.

Both these options come with associated costs, pros, and cons. If you’re confused between a gun safe and a gun safe room, look at the pros and cons of each and then decide.


Pros of a Gun Safe Room:

  • It can hold a large number of firearms
  • Can be used as a panic room/storm shelter
  • Allows room for more weapons

Cons of a Gun Safe Room:

  • Takes a lot of your home space
  • Is very expensive to build
  • Not always fire rated


As we wind up, a gun safe room is a must-have facility for any individual or institution that is in legal possession of firearms. It ensures that the dangerous weapons are kept out of reach of minors and other unauthorized personnel. It is crucial in the sense that it prevents burglars from using your armory in the case of a break-in.

As mentioned earlier, it can also serve as a centralized place of refuge inside your home in the case of an attack. Since a gun safe room serves a purpose of paramount importance, its building process must be executed with all due diligence because you really cannot afford to have its security breached.

So that’s everything you need to know when considering how to build a gun safe room at home!
