How can you bring light and order to a dark, split-level dysfunctional kitchen? How can you bring together indoors and outdoors when the two don’t quite join up? Tucked behind a brick wall, our glass-topped ‘black box’ extension does everything at once, lifting the spirits, bringing order to the kitchen, and leading you through from the house to the garden. And a little lantern by the back door lights the way. It’s a mini version of the door itself, and a clever finishing touch.
