Are you considering building your own bunker or nuclear shelter but don’t know where to start? We spoke with two experienced bunker builders and visited a bunker to ask experts for explanation.

In an earlier article we already discussed that there are hardly any (nuclear) shelters in either the Netherlands or Belgium. If a nuclear attack or disaster occurs, it’s best to look after yourself.

Custom-made shelter

We spoke with two companies that build bunkers to order. We had a telephone conversation with RevBunker from the Netherlands – they recently moved their production line to Portugal. Managing director Ferriën Mertens – who has a background in shipbuilding – explains that he focuses on bunkers that can withstand nuclear incidents.

We also visited the showroom of DR-Bunkers Bunkers from Belgium. They specialise in above-ground ‘mobile saferooms’: containers that receive a bulletproof layer, can be equipped with filter systems and off-grid systems designed to spend a shorter period in. They deliberately do not focus on the – albeit more expensive – market of underground shelters.

Are you considering your own bunker?

Are you thinking about building a bunker or shelter yourself? Or have you already ordered one from a specialised company? Share your own findings or experiences about ‘subject’ in a comment below!

The characteristics of a good bunker

Both companies focus on a specific market and claim to guarantee a certain quality. Ferriën from RevBunker considers these the most important characteristics of the shelters he builds:

  1. Protects against nuclear incidents
  2. At least 2 metres underground
  3. Strong construction

Peter from DR-Bunkers indicates these important aspects of a bunker:

  1. Discreet appearance: resembles a standard shipping container – neighbours don’t see that it’s a shelter.
  2. Ballistic protection: fitted with bulletproof steel against bullets and explosions
  3. Accessible design and can be placed without a permit

Question

Ferriën (RevBunker)

Peter (DR-Bunkers Bunkers)

Why did you start building bunkers?

“You have to look after yourself, because the government really won’t do it. There are no public nuclear shelters.”

“With the world becoming uncertain, I primarily wanted a place for myself and my family to shelter and stay overnight safely.”

What do the bunkers protect against?

“The shelters protect against nuclear incidents.”

“The bunkers – or saferooms – are bulletproof as standard and can be reinforced as desired.”

Above ground or underground?

“At least two metres underground.”

“They are placed above ground, e.g. discreetly in a garden.”

Delivery time

2 to 3 months

4 to 8 weeks

Price range

From 190,000 euros

From 33,000 euros

How long can I survive?

“In theory: for months! The biggest challenge is being able to cope with it mentally.”

“They are intended for spending shorter periods in.”

How long do you stay in a bunker?

“In a nuclear incident with tactical nuclear weapons – so not with a weapon of total destruction – you’ll only have barely 10 per cent of the radiation left 7 hours after the attack”, says Ferriën. Nevertheless, he advises staying in the shelter longer. “We recommend spending 14 days in it.”

DR-Bunkers’ panic rooms are intended for short-term crises. “It’s not intended to lock yourself in for months”, he explains. “It’s really intended to have a safe place if something occurs.”
