THIS ordinary 1950s home may seem basic if you're looking from the street but it holds an incredible secret inside its walls.
Mike Parrish has called the spot his home since 1994 - and has kept its wartime panic links alive ever since.
The owner says he has been offered £30,000 just to be a host - and now even shows people around the vast building, and what lies beneath.
hides a secret nuclear bunker built during the Cold War to house up to 600 people, including the Prime Minister.
Those lucky enough to cop an invite to the Essex bunker bash would be tasked with reconstructing civilisation in the fallout of a cataclysmic bombing by a foreign force.
Originally built in 1952 by the Air Ministry, the "Kelvedon Hatch" is guarded by a bungalow, which conceals a 120m tunnel leading to the underground shelter.

Generators stand to the left of the bungalow, offering up to three months of continuous power.
The bungalow and tunnel boast thick reinforcement designed to protect the shelter from the initial blast and consequent radiation.
The government kept the bunker on standby until 1992, when the Cold War fizzled out.
It had been spending £3million a year just to maintain it.

Mike bought the property in 1994, now running it as a museum.
Mike, a farmer, previously revealed he received extraordinary offers of up to £30,000 for places in the bunker following 9/11.
He claims he keeps water, tinned food and a sewage system under there in case of a new global conflict.
Russia's war on Ukraine has renewed interest in the shelter, but Mike in 2023 said he would drive a hard bargain.
He told The Express: "Of course, I've learned that I say 'well, if you've got £500,000 in liquid assets, we will talk to you'.
“On 9/11, I had over 200 people… part of the deal was that in those days, we said for £30,000, we will guarantee your space, down in the bunker here for 10 years
"You are going to be down here for 10-15 years, you're going to want lots of food.
Four-bed house hides incredible secret behind closed doors
By Owen Leonard
THIS historic £300,000 home boasts its own mystery feature that many could see as the perfect escape.
Located in Fowlmere, Cambridgeshire this four bedroom cottage has one bathroom and 1,356 square feet of living space.
It also claims a chalk-etched tunnel used as a hiding place during the reign of Henry VIII.
The Grade II-listed cottage was built over the secret passage, which links up with several historic properties in the village.
It's said to play host to a small central meeting room, too.
The tunnel was likely built when Henry VIII created the Church of England, vendors say.
This could be the last remaining access point to the tunnel, with others having been sealed off.
The passage stretches for 100 feet and its only access point is through a trap door in the cellar of the four-bedroom house.
According to historical records, the tunnel, which is 5 foot 9 inches at its deepest and just under a yard at its narrowest points, extends under the road towards Fowlmere's war memorial.
There it changes direction towards the Old Manor House on the other side of the High Street.
The house has been Grade II-listed since the 1960s by Historic England, which cites that "from the cellar a tunnel cut into the natural chalk leads to the Old Manor House".
"People are superficial, you know, they still think you go down underground, come up (the) next morning and carry on working – you won’t.
"If there is that sort of thing (a nuclear strike), you're going to be underground, and you're going to be down there for as long as it takes."
Mike added that his wife had already decided against moving to the underground refuge in the event of a major conflict.
It's not the only home across the country to hide secrets within its walls.
A homeowner found an entire room so well hidden that not even the previous tenants knew.
Posting his discovery to TikTok, owner Daniel pulled off a mysterious wooden panel and broke through insulation to find the secret space.
