If a concrete home leaves us cold we'll often describe it disparagingly as a bunker. So what happens when that concrete home is actually a bunker? If it's this penthouse apartment atop a WWII above ground bunker in Hamburg, Germany what could have been sterile and oppressive is instead raw, warm and sophisticated. The loft-style space has four metre floor-to-ceiling windows, is filled with contemporary designer pieces and has two big balconies offering amazing views over the city. What makes this beautiful apartment even more exciting is that it is part of the luxury vacation accommodation offered through Welcome Beyond. It's available from March 2017. In the meantime we can daydream of a getaway to help us through the Friday grind.
