A couple exploring their new home were shocked to find a hidden room at the back of a kitchen cupboard that is complete with a window.
The secret space has left the two new unnamed renters wondering why it is there and they have taken to social media to share their surprise.
There is, however, no door to access the room normally. It has no flooring, and still appears to have some wiring and building materials left inside, reported the Daily Star.
According to Yahoo News Australia, an unnamed woman from the UK posted the incredible find on a Facebook group called Things Found in Walls - And Other Hidden Findings.
Sharing her surprise, she wrote: "Just rented a flat with my boyfriend and found a room inside our kitchen cupboard.
"Definitely gonna leave something weird in it for the next tenants when we move out."
Fellow members of the group commented in astonishment, and offered some theories on what the room might be for.
One mum posted: “I would turn it into a hide out to study or hide and eat my kids' fave snacks so I wouldn’t have to share with my kids.”
Another aggrieved mother wrote: “I would totally make that into a comfy little hiding spot. Husband getting on your nerves? Run to the hiding spot.”
Others were more outlandish with their guesses. One joked it could be the potential work of a serial killer, saying: “Perfect place to hide the bodies.”
Alternatively, some took a scathing look on those who built the property, calling it a "waste of good, natural light."
Last year, a pair of new homeowners discovered a secret hidden room under their staircase which turned out to be an amazing "treasure trove".
The family, thought to be from America, got more for their money after they discovered it contained bottles of wine - some of which were more than 50 years old.
