It's not unusual to see couples struggling with their relationships while appearing on Grand Designs. After all - the pressure is high: expensive project, inevitable overspend, and Kevin McCloud beadily assessing your work. It's extremely hard to do it without a camera being shoved in your face - and thousands of viewers judging you for going over your budget.
For some couples, the pressure ends up being too much - as it did for Edward and Hazel Short, the pair behind one of the most well-known properties to appear on Grand Designs.
Dubbed one of the saddest-ever episodes, Kevin McCloud will tonight revisit the infamous build in a special episode airing tonight.
