A bomb shelter boss 'wants North Korea to launch a nuclear attack' to help sell 'high street bunkers'.

The bunkers have been built to withstand a nuclear attack by Kim Jong-un are now being sold on Seoul’s high street.

British bunker experts Castellex have been working alongside the Korean company Chumdan Bunker System on making the world’s toughest shelters to prepare for nuclear war.

A ‘bunker showroom’ has now been opened in downtown Seoul, in the same shopping area where people are buying clothes and cosmetics.

CBS owner Go Wan Hyeok says that demand from 'petrified' locals for affordable bunkers led him to set up in the busy retail district of Jangan-Dong - and wants to branch out to Europe and the UK within five years.

He said: "I'm wishing that he presses the button and shoots the bomb!

"I think more people will be selling bunkers on the high street in the next five years but I’m the first in the world. I want to then open up showrooms in Europe and my friends in the UK."

Kim Jong-un launched yet another ballistic missile in the early hours of Wednesday morning.

The missile was said to have a range of 8,000 miles, meaning it was capable of hitting Washington DC, Europe and Australia.

Hyeok said: "I started the company in September, but I’ve been researching this for a long time and travelled all round the world.

"Before, they were not radioactive-proof in Korea, and very expensive, then after spending time in Switzerland, the US, Australia and the UK, I came up with the most perfect bunker.

"I did everything to build this, I researched all the products, I’m completely unique.

"This showroom is for people passing by who want to buy one. Most bunkers are underground, so people can’t see before they buy, so I had this showroom built.

"People could see for themselves what it’s like, experience it in reality.

"These bunkers are everything-proof! Outside the military, this is the first bunker like this available for civilian use and is totally affordable.

"For a family of four, it costs 30 million WON [approx £20,000].

"This is certainly affordable for most families in Korea. We can make them any size.

"It takes three weeks to make one. We have lots of people come into the shop and our team of ten are getting calls every day."

The bunkers come equipped with solar panels and self-winding generators, which can last upto a month underground.

There’s four beds - although customised models are available for unto eight people - space for a computer, TV, fridge and other home essentials.

There’s even a CCTV periscope so that you can see outside.

The food kit is straight out of the military and NASA, mostly dry products which take up little space and easy to eat.

In case of a nuclear or radioactive explosion, there’s a survival pack including gas masks for all the family, chemical-proof goggles and gloves, tool kit, and special balaclavas which can be worn in the event of acid rain.

The air ventilation system was made by the British company Castellex, which Hyeok says is the best in the world, adding: "We build the main framework in Seoul but import a lot of the stuff from the UK. We use Castellex air ventilation systems as they’re the best.

"There are standards in the UK, US and Japan. I have made them better than that.

"I have imported the best nuclear, biological, chemical system possible, so when the standards say 7cm thickness for the doors, we make it 8cm."

On it’s website, Castellex says its ventilation system is prepared for any nuclear fall out, stating: "A panic room, bunker, or bomb shelter only goes part of the way to protecting your family and possessions.

"In the event of a nuclear, biological, or chemical attack, you need to be able to control the environment inside your protected space. Castellex fallout shelter ventilation systems are built to give maximum peace of mind.

"They will operate efficiently in critical situations, and provide permanent protection for everyday installations such as homes in areas with a high allergen or pollution count."

Castellex spokesperson Valdys Macys adds: "Our systems are compact, easy to install and maintain, really user friendly and, very importantly, they are reasonably priced.

"It means it’s affordable for most people. Companies like Chumdan Bunker System usually do big research before taking products onboard.

"At the moment we truly believe we have the best air filtration systems in the market for small domestic bunkers."
