Kirstie Allsopp and Phil Spencer look back at loft conversions, remembering two families who wanted to transform their dark and dingy attics in the race for space. In Walthamstow and Preston, two couples are looking at starting families, but lack of space is an issue - and while one would prefer to move on, the other is keen on a loft conversion. As ever, Kirstie brings in the builders, while Phil sees what other properties are available.
