Proving you can never have too many 'house reveals', Kevin McCloud follows the conversion of a large, Grade II-listed timber-framed barn in Essex into a family home and work-space for oooortists. Freddie Robins and Ben Coode-Adams (indeed) are leaving their modest urban flat to create a massive 'free-form contemporary space' (of course) with very few walls, to display their ever expanding collection of toys and ephemera (... sure). But at seven times the size of an average three-bedroom house, turning this 500-year-old building into any kind of home is a challenge. As Freddie and Ben grapple with the scale of this project they begin to question whether their quirky ideas are workable. For this young family, this conversion will transform their lives, but is there such a thing as too much space? And can a cavernous barn like this ever make a cosy and comfortable home?
