Kirstie Allsopp and Phil Spencer look back at favourite editions featuring homes full of collections and clutter. In Somersham, Kris and Emily have a £50,000 budget for a first-floor extension to add a fourth bedroom, which Kris thinks will sway Emily back to loving it. But Kirstie is convinced they already have the space they need and embarks on her biggest-ever declutter. They also travel to the Edinburgh suburb of Portobello, where Gary and Bill are at loggerheads over their 19th-century home which is full of Bill's music memorabilia.
