THIS tiny concrete "shed" is on sale for £283,000 but it comes with a mind-blowing secret hidden beneath the ground.
The 6,900 square feet bunker is home to a set of stairs which lead down into a decommissioned US missile silo complex.
Located in the heart of Kansas and built on 11 acres of land, the hidden concrete structure was designed to withstand a nuclear strike, according to real estate website Zillow.
It has everything a modern family would need to survive the apocalypse including running water, electricity and a forced sewage system to the ground surface.
It even has an upper two levels that are 1,200 feet in size and is only accessible via an eerie above ground entry.
The old launch site was home to an Atlas F missile silo complex which housed Intercontinental Ballistic Missiles (ICBM) between 1961 and 1966.
When it was active, the silo was manned by a five-person crew and has a underground tunnel connecting it to a launch control room some 170 feet underground.
The sites later used in the US space programme and helped launch the first four American astronauts to orbit the Earth in the early 1960s.

Hirsch Real Estate is trying to flog the property which it describes as a "one room building for office or storage".
"This facility has lots of potential in whatever way you choose to go," the online advert goes.
"A home, apartments or a Bed and Breakfast are just some ideas.
"If you want something offering security and uniqueness, then this property is for you."
The F series of Atlas missile silo complexes were the last of the ICBMs bases to be built and cost £11million each in the 1960s, according to atlasmissilesilo.com.
According to the website, there were 72 Atlas F launch sites across the US – with Kansas being home to 12 of them.
This bunker was located in Abilene and was the Schilling AFB site.
The agent said: "Built on 11 acres of land, this property is home to a decommissioned Atlas F missile silo complex.
"The underground complex was designed to withstand a nuclear strike and has water, electricity and a forced sewage system to the ground surface.
"There is 6,900 square feet in the complex with the upper two levels consisting of approximately 1,200 feet of space.
"This area was used for the Launch control center and living quarters for the crew. The main missile silo is located at a depth of 170 feet."
The silo would have been once home to an SM-65 Atlas – the first operational ICBM developed by the US.
Standing 75ft high and weighing 260,000lbs, the one stage rocket was a key part of Washington's arsenal during the Cold War.
The weapons could be launched from the underground silos or from coffin-like bunkers.
Atlas missiles were equipped with a W38 thermonuclear warhead which had a yield of around 3.75 megatons.
