In brief
A panic room is there to give your family time – from the moment something happens until the security company or the police arrive – so it is designed with a margin measured in hours, not days. The decision about it is made together with the structural design, because reinforced partitions, separate ventilation and independent communication have to go in together with the walls, and adding them to a finished house gives less protection for more work. I design and build it as part of the whole house, together with the other layers of its protection. I do not talk anybody out of a panic room – if somebody wants one, we are able to build it. This text says which decisions have to be made and what to require from the people who will build it; it does not say how such a room is built.
Why I will not write how such a room is built
Panic rooms are among the projects I carry out, alongside a pool below the groundwater level and a car lift. But I do not publish descriptions of the solutions, and I explain why in the text on residence security in layers.
I write about this room because there is little matter-of-fact writing about it here in Poland: what you find is either sensationalism or a door catalogue. I stop, though, at the level of the owner’s decisions and the questions to put to a specialist, because everything below that level is already a description of a particular house. A panic room works better the fewer people know anything about it, and a public description of solutions would spoil exactly what it is meant to protect.
What a panic room is – and what it is not
In films it is a steel chamber with a wall of monitors, where the family spends half the plot. In practice it looks far less spectacular: it is a room designed for one scenario – shut the threat out, call for help and hold out until it arrives. Its whole point can be put briefly: time, not a fortress. Designing for a day or longer, with water, supplies and air-quality control, is a separate and much more demanding class of requirements, and rooms meant for weeks belong to a different category of structure altogether, built for other scenarios. The name varies – panic room, safe room – and the name happens to be the least important thing here.
What counts first of all is how long it takes to get in. A room you cannot get into within a dozen or so seconds, straight from the bedroom wing, will not do its job, however strong its door, and the floor area is a secondary matter.
The second thing: the level of protection is decided by the weakest element of the whole. A very strong door in an ordinary partition wall is decoration, like three locks on the front door with the kitchen window left ajar. Nobody attacks what is strongest; they look for the weakest and least visible spot, so the structure, the service penetrations, the ventilation and the door have to be designed together, as one assembly.
The third thing is autonomy: independent ventilation, independent power, and communication that works even when the electricity and the mobile network are down, ideally over two separate channels. A room that locks well but does not let you call for help solves half the problem.
The fourth thing, talked about least, is discretion. A room that too many people know about loses a large part of its value, which is why the way the build is run matters here as much as the performance of its walls; I will come back to that below.
None of this is exotic, either. In Israel a reinforced room in every flat has been a mandatory part of new residential buildings for more than 30 years, for reasons I wish on nobody. In Poland it is still rare, and you find it in houses whose owners have a specific reason to think about it.
Who really gains from this room
The conversation starts with the risk profile, that is, with the answer to the question of who might want to enter your house uninvited and why, and what you are really afraid of. The profile depends on how publicly recognisable you are, your industry and how visible you are in business, the value of what you keep at home, the location and how long the emergency services really take to get there, and finally the family’s way of life. I have that conversation with you at a meeting, not in an article, because its outcome is already a description of your house.
If that conversation shows a heightened risk to people, a panic room is a rational part of the house’s protection. If it does not, you will not hear from me that there is nothing to talk about. I think a panic room is a great thing, and I have no reason to talk anybody out of it; I will simply explain what provides protection instead when there is no threat directed at people: the fence, the windows and doors, and an alarm, which acts as a deterrent even in its simplest form. You use the layers of the house’s protection every day, while a panic room waits for a day that, I hope, will not come for you.
On top of that there are two limits you need to know about before deciding. The first: a panic room does not protect against fire or flood, because another part of the design addresses those scenarios – detection, separation, escape routes – and the room itself has to be coordinated with the fire protection so that it does not become a trap in a fire. The second: the room on its own settles nothing if the family does not know how to use it. You have to know when to go in, how to communicate from inside and what not to do, and that is not something you make up on the spot; it is practised and repeated. Contrary to appearances, what comes out of that practice is more often calm than fear, because knowing that a plan B exists and works lowers everyday tension instead of feeding it.
The decisions made together with the structure
With ordinary installations you can leave a door open for the future. Cables for an alarm or cameras can be run just in case, together with the electrical installation, and left under the plaster if in the end nothing gets installed. With a panic room that trick does not work. Reinforced partitions, connection details, a separate ventilation route and independent communication cannot be put in just in case or added along the way – either they are in the structural design or they are not, whatever the technology: reinforced concrete, steel or a modular system.
Everything that will disappear into a wall is inspected in stages, before it is covered, because afterwards a mistake can no longer be put right cheaply. With a panic room there is an extra condition an ordinary build does not have: that inspection has to take place without widening the circle of people who know what it is all for.
Adding such a room to a finished house is possible with modular technologies, but it is a compromise by definition: a lower level of protection for more work and time. So if you are seriously considering it, tell your architect and your contractor before the structural design is drawn up.
The decisions that will be yours come roughly in this order: what the room is meant to protect against, because protection against everything does not exist; how many hours the ventilation, power and supplies are designed for; for how many people – the household alone, or the family together with guests. Then it has to be settled where in the house it goes, and the way there is measured in seconds, not metres; who is to know that the room exists at all; how it is to work with the house’s systems while staying independent of them; and whether it has a second use day to day, which is acceptable provided the second use does not weaken the first.
Three requirements that test a specialist
You do not need to know the technology. Three requirements put in plain words are enough, and from the answers you will quickly tell whom you are talking to.
The first is classes instead of adjectives. The partitions and doors of panic rooms are described by resistance classes: bullet resistance under EN 1522 and EN 1523, and burglar resistance in RC classes. Classes are nothing exotic in building, either – even ordinary burglar-resistant windows and doors have them, with the glass carrying its own class and the hardware its own. The point is that a class only makes sense for a tested assembly, compatible with the wall, the fixings and the service penetrations; it is not a sticker you buy along with the door. It is not about you reciting standard numbers, but about the fact that a specialist answers a requirement put like that with specifics, and a salesman with a story about armoured doors.
The second is autonomy described in hours. The requirement then says how long the room has to hold out on its own, and a requirement like that can be calculated and later checked. The ventilation and filtration have to be calculated, because in a sealed room the first problems are carbon dioxide and temperature. You know the mechanism from everyday life: in a bedroom with the door and the window shut, the air is stuffy by morning, and here it happens faster, because the room is smaller and far more airtight. On top of that come emergency power with automatic switchover, and lighting.
The third is communication with redundancy. At least two independent channels are needed, designed on the assumption that in the worst scenario neither the power nor the home network works, and on top of that an alarm signal to the monitoring station, with a clear procedure for who verifies the alarm and when the police are called. I describe separately, in the text on the alarm system in a residence, how the whole response layer of a house is arranged.
The reaction to these three requirements tells you a great deal about the person you are talking to. Somebody who understands them will ask you further questions: about the scenario, the family, the house. If the conversation circles around the price of the door from the start, the two of you are talking about something other than a panic room.
Who is to know about it
This is what clients ask about most often, and rightly so, because how discreetly the work is done decides the value of the room.
The documentation is thorough and complete: the structure, the services and the requirements of the room have to be covered in full in the design, otherwise it could not be built properly and legally. What does not have to appear in it anywhere is the colloquial name, and what the room is really for is known to a small circle: you, the designer and me. Discretion comes from who knows the room’s function, not from building outside the design.
The rest is a matter of how the build is run: photography is forbidden on it, every person is checked by name, and nothing is published after handover. I will not write more about the organisation itself, and I explained why at the start.
That leaves the servicing, which hardly anybody thinks about at the moment of the decision. Every inspection, every repair and every replacement of equipment widens the circle of people who know something, which is why the rules of access are agreed when the room is planned, not after a year of use: who comes in and on what terms, what they see and what they leave behind. I have collected answers to the most common questions about privacy in the Questions section.
When it is not worth it
When the house already stands and the expectations are as high as they get. Adapting it is feasible; the only question is how much work it takes and what level of protection it really gives, and sometimes a modular solution with reasonable performance makes more sense than trying to achieve a resistance class the existing structure cannot support anyway.
When the panic room is meant to replace the system. A panic room is the last layer – after the fence, the detection, the windows and doors and the alarm – and whoever starts a house with it is building a roof without walls. I describe how the layers of a house’s protection fit together, and how much time each of them gives, in the text on layers I mentioned above.
When nobody intends to maintain it. The emergency power, the ventilation, the communication and the locking need periodic tests, and the family needs to go over the procedures again; if nobody checks, after a few years nobody knows whether the room will work at all.
I do not promise that a panic room will protect against every scenario, nor that it can be added later without compromises. And I will not tell anybody, publicly or privately, about the solutions used in particular clients’ homes.
What I ask before I say yes
- Who and what is this room meant to protect against?
- Is the structural design still ahead of us, or already done?
- Who – by name – is to know that this room exists?
- What scenario are we designing for, and how long must the room hold out on its own?
- What does communication look like when the power and the mobile network are down?
- Who will service the room’s systems, and on what terms, so that the number of people who know about it does not grow with every inspection?
Frequently asked questions
Is a panic room at home legal in Poland, and does it need separate approvals?
It is created within the normal design process for the house, and there is no separate procedure for a panic room. It does not have to be described by name in the documentation, and its purpose is known only to the owner and a small circle of people involved in the design. The formalities – a building permit or a notification (the simpler procedure Polish law allows for some works), a new house or a conversion – are worked through with the designer at the concept stage, and I check the state of the regulations as of the day of the decision.
Can a panic room be made in an existing house?
It can, with modular technology installed inside an existing room. It is a compromise between the level of protection and what the existing structure can carry, and it usually takes more work than a solution planned before the structural design. Full performance comes when the room is in the design from the very first sketch.
How much does a panic room at home cost?
I do not price it by the square metre or from a catalogue. The cost depends on the stage at which the decision is made, on the level of protection, how long the room has to hold out on its own and the communication, and the same level of protection planned before the structural design costs a fraction of an attempt to add it later. We talk about the cost in concrete terms only once it has been settled what the room is to protect against, because before that nobody knows what is actually being priced.
Does a panic room protect against fire?
No, and it should not be sold that way. Fire protection is a separate layer of the design: detection, separation and escape routes. A panic room is designed to protect against threats from people, while the house needs separate measures for fire; the two have to be coordinated.
If you are thinking about a house in which security is designed in from the start, this conversation should take place before the structural design is drawn up. Let’s talk about your project.
