It's a home designed for the more adventurous explorers who are willing to leave planet earth and colonise another world.
The building is a mock-up of a facility that would-be colonisers could use to survive on Mars.
It was built with the help of the writer Stephen Petranek, who wrote 'How We'll Live On Mars'. His book was also part of the inspiration for the upcoming miniseries 'Mars'.
"This is a typical Mars home if you want to call it that but it's really a survival centre. It will make oxygen for people to breathe and it will supply it's own water by sucking in the martian atmosphere which is 100% humid most nights."
Colonisers will find room to grow plants, exercise and communicate with earth inside the pod. Petranek also said there are a number of reasons to leave earth and head for the red planet.
"Well, it's possibly the greatest adventure of anyone's lifetime to go that far and see something so unusual and to live in an environment that is so unusual but there will be a camaraderie about living on Mars that will be very attractive. Salaries on Mars will likely be higher than they are on earth. There will be jobs on Mars galore."
The show home is due to be on display at the Royal Observatory in London until Wednesday (Nov 16).
