Planners have pretty much seen it all, but occasionally an application lands on their desk that takes them by surprise. In this episode, one young couple wants permission to set up a dog hydrotherapy centre,and another couple wants to build where no-one else would dare.Both applications have significant financial repercussions. The dog hydrotherapy centre is an investment that could yield real returns, and the couple building their dream house could end up with a million-pound finished property. There are problems in the form of a great crested newt and a lapsed application, but both couples prove that when it comes to planning, persistence pays.
