Amanda and Alan face their final challenge as they join forces to renovate the last two rooms. Their dream of creating an open-plan living and dining room is dented when they discover the main structural wall dividing the two spaces requires a much smaller arch than they anticipated. For this final space, they agree to put their design differences to one side, but a disagreement over the shape of the arch threatens to divide them. Wanting to make the rooms feel as authentic as possible, Amanda and Alan take a boat trip along the stunning Zingaro nature reserve to get inspiration from the Sicilian landscape, and they enjoy sunset on horseback in the ancient Greek city of Selinunte.
