Kirstie and Phil look back on two sets of couples who struggled to decide whether to stick to their roots or move on to pastures new. In Wandsworth, south London Rachel and Tim debated over city or country. While they both agreed their 1930s semi was too small for their family of four, how to move forward was their issue. In Lincoln, Carly and Eric had a similar situation with their two-bed bungalow being too small for them and their family and while Eric thought their only choice was to move, Carly was adamant she wouldn't leave her close family support network behind.
