In the second episode, George Clarke is joined by leading architects to help transform a house belonging to Nick and Sonia, an appallingly designed flat spread over three dysfunctional car parking spaces. George charges award-winning architects Abigail Ashton and Andrew Porter with creating something beautiful from this monstrosity. But working with a budget of £75,000, can they transform this foul flat into a proper home with two floors? And what will the pair's neighbours make of the drastic changes?
