Railways in Ireland have been around for almost 180 years, and when they first arrived they brought Ireland to the forefront of technological change. Having once enjoyed a golden age, railways were to enter a long period of decline - but today their revival is being championed once again.

In this episode, Paul and Blanka and their two children attempt to construct an eco-home on Plot 6 of the street.

However, the project ends up costing the family more than they bargained for, and not just financially.
