EMP Safe Rooms LLC · Custom protective construction

The last room
standing.

We design and build custom safe rooms engineered for the failure modes you choose — intruders, earthquake, fire, flood, lightning, EMP, grid loss — provisioned for months of self-sufficient living.

Sys.01 — 08

Choose what you're
safe from.

Every room starts with a hardened structural core. From there, you select the protection systems that match your threat model — each one engineered in, not bolted on.

SYS.01

Forced Entry & Ballistic

Steel-cored wall assemblies, ballistic-rated door and frame, multi-point locking, protected sightlines, and safe-side egress you control.

SYS.02

EMP & Solar Storm

A continuous Faraday envelope with shielded penetrations and filtered power feeds — plus protected storage for the electronics you'll want after.

SYS.03

Earthquake

An independent structural cage engineered for seismic loads, optional base isolation, and restrained racking so your supplies survive the shake too.

SYS.04

Fire

Fire-rated envelope assemblies, ember-sealed penetrations, and an independent, filtered air supply that keeps the room breathable.

SYS.05

Flood

Watertight door thresholds and sealed penetrations, sump and backflow protection, with power and stores mounted above the waterline.

SYS.06

Lightning & Surge

Bonded shielding, staged surge arrest on every conductor entering the room, and an isolated grounding system that gives strikes somewhere else to go.

SYS.07

Power Loss

Battery banks with generator or solar integration, shielded charge electronics, and manual overrides — the grid becomes optional.

SYS.08

Extended Stay

Food and water for multiple months, air handling, waste management, communications, and a living fit-out sized to your household.

Process

From threat model
to turnkey.

  1. 01

    Threat consult

    A private conversation about what you're preparing for, who the room protects, and the site you have to work with.

  2. 02

    Engineering & design

    Site survey, structural engineering, and full drawings. You approve every system, finish, and provision level before anything is built.

  3. 03

    Build & integration

    Licensed crews build the core and integrate your systems — new construction or retrofit, always discreet.

  4. 04

    Commissioning

    We test everything with you in the room: door cycling, shielding verification, air, power failover, comms. Then we hand you the keys.

About

Built like it's
ours.

EMP Safe Rooms LLC is a specialist design-build firm. We don't sell kits and we don't do off-the-shelf: every room is engineered for its site, its household, and its owner's threat model.

One team carries your project from the first conversation through commissioning, and everything we install is testable — you'll see the door hold, the power fail over, and the shielding verified before we call it done.

Discretion is part of the product. Your plans, your address, and the fact that you have a safe room at all stay between us.

FAQ

Fair questions.

Where can a safe room go?

Almost anywhere with sound structure: basements, garages, interior rooms, additions, or standalone buildings. New construction gives the most freedom, but most of our work is retrofit. The site survey settles it early.

What does a room cost?

It depends almost entirely on size, site, and which systems you select — a hardened interior retrofit and a standalone multi-month shelter are very different projects. After the initial consult you'll get a scoped range before committing to anything.

Do I have to choose every protection up front?

No. The structural core is the only permanent decision. Systems like extended-stay provisioning, power, and surge protection can be added later — though shielding and flood sealing are far cheaper to build in from the start, and we'll tell you which is which.

Does EMP protection really require a full Faraday envelope?

For dependable protection, yes — partial shielding fails at its weakest seam. That's why our envelope is continuous, penetrations are shielded and filtered, and we verify performance at commissioning rather than asking you to take it on faith.

How long can the room sustain us?

Provisioning is sized to your household and your target duration. Multi-month autonomy — food, water, air, power, waste, comms — is a standard configuration, not an exotic one.

How private is this?

Completely. We limit who's on site, plans are shared on a need-to-know basis, and we never use your project for marketing. Even this website's contact form delivers straight to us with no third-party form services in between.
