A doting dad has transformed his staircase into an incredible adventure course so his son can practice his love of rock climbing at home.

Michael Mason, 37, created the £700 structure for ten-year-old Leo, who has Tourettes and aspires to be a professional rock climber when he's older.

He uses the wall a couple of times a week and an incredible video shows him going upstairs in the three-bedroom terraced house by climbing the DIY rock face.
