Trains addiction has pushed Vanessa Stallbaum and Marco Stepniak to use two old mail cars in the design of their new house.

They have bought these two second-hand mail cars via an online store for just $ 29,000, though transporting them from Switzerland to Germany actually cost more than the cars themselves – $37,600.
After the two mail cars were cleaned and repaintedhired, the couple hired an architect to make a house plan according to their drawings. Converting the cars was much tougher then they have expected, but they somehow got it done.
