Dom Chinea and his wife Maria (plus their dog Wendy) are moving to Cornwall, having bought an old rundown stone farmhouse, a two-acre field, including a large agricultural barn that Dom is going to turn into his Cornish Workshop. The new series follows Dom as he carves out a new life in the far west of Cornwall. He carries out automotive, engineering and build work, as well as helping neighbours and his new community with their projects.

From buying and fixing an ancient four-wheel drive to enable year-round access to his new workshop, to helping his local church with their bells, to creating a bespoke ice cream vehicle for his neighbour, every episode packs big and little stories alongside the narrative of creating his new workshop from an ancient barn. Throughout the series, Dom enlists the aid of Sam Lovegrove for general engineering assistance, plus a cast of charismatic, local trades people who collectively help Dom to achieve his ambitious plans.
