Claire and David Lynch in Rainham, Kent convert the loft in their 1960s family home to create a master bedroom and ensuite shower room and demolish the chimney stack to create more space in their narrow sitting room. Before the builders descend, Amanda Lamb takes them to visit neighbours who have already revamped their homes to get advice about making the most of space in a loft conversion, choosing colour schemes to maximize light, and fitting a new fireplace.
