Buildings are creatively converted or utterly demolished all the time to make room for highways and other large-scale civic problems, but the laws vary on what can be done when a single hold-out structure stands alone against a sea of fat-cat developers, builders and architects who all want nothing more but for them to move.

Sometimes they successfully force out residents or bribe them with offers that range up to 20 times the value of the home and real estate – but in many cases they simply have to give up and build around them, creating so-called ‘nail houses’ that stand apart from their surroundings.

In some cases, these incredible stand-alone structures have huge fan bases of individuals who applaud their willingness to stand up for their property.
