Dick, Angel, Arthur and Dorothy enjoy a magical festive adventure in this Christmas episode, with a family celebration inspired by a very special part of France - Colmar in the Alsace region, close to the German border. They discover an enchanting medieval town that makes Christmas feel more magical than ever. It's not long before they are taking part in a festive treasure hunt, sampling local baked delicacies, trying their hand at fondue, and discovering the ice and crémant wines that the region is synonymous with. Back at the chateau, the Strawbridge traditions are not forgotten. Angel, her mum Jenni and Dorothy head out into the chateau grounds to collect the fir and foliage to make the annual Christmas wreath.

The wooden double front door with its delicate metal tracery, the metal awnings over the windows, and the stone balustrade edging the front steps, are all in a state of disrepair. Angel's father, a former jeweller, steps in to try and make a copy of the huge 150-year-old key to the front door. The family goes to the beach to collect razor clams.

Angel sets about restoring the Chateau's walls to their original glory using computer mock-ups to try and match the existing colour. Part of a traditional device used for making cider is discovered while clearing out the piggery, so the hunt is soon on to locate the rest of it. Inspired by the ancient piece of machinery, the family collects apples to make their very own juice.

Angel discovers that the chateau has a vast attic space running the length of the building and rising to the ridge of the roof. While Dick is glad to have some more storage space, Angel has bigger plans - transforming it into a space-inspired bar complete with balconies from which they can watch the stars. The project will require skylights, a new staircase and unique use of insulation - but proves worth it when a cloudless night provides the perfect chance to look for shooting stars.

Arthur and Dorothy are now seven and eight, and growing up fast. They will soon need separate bedrooms - so Angel comes up with an ingenious plan to create a mezzanine. As the re-slating of the roof continues, Dick and Angel not only launch into knocking down walls and building new ones but preserving old wallpaper, creating memory furnishings from the kids' old clothes, as well as finding time to pick some strawberries in the garden.

With life a bit quieter than normal, Dick and Angel throw a Great British garden party for Arthur and Dorothy's friends, and work finally starts on re-slating the chateau roof

Dick and Angel start work on the biggest, messiest and most expensive job they've ever done at the Chateau - repairing, re-tiling and re-insulating the whole of the original roof. They also transform the preserves cupboard and go hunting in the walled garden for ingredients to make home-grown mint tea and rainbow sweetcorn relish.

Dick, Angel, Arthur and Dorothy share more enchanting tales from the Chateau, as they continue the renovation of their 19th-century fairytale home and grounds. With weddings and events on hold for the second year, Dick and Angel bite the bullet and make the big decision to tackle the exterior of the Chateau. The roof and outside walls are their biggest project to date and the Chateau quickly becomes a building site.
