About this programme

The architect returns for a festive special revisiting some of the series' small-build projects. He catches up with expert designer William to look back on his project to transform a 1970s caravan into a holiday retreat, and meets the couple who invested their life savings in the conversion of an old bus. Plus, the disused underground toilet turned into an apartment, the office inside a shipping container, and Christmas-themed builds including a gingerbread house and a beach-hut advent calendar.
