Triangle in the kitchen = important rule. It is an ideal distance between space, which is used for storage of good (fridge), space used for washing (sink), and cooking space (cooker).
These points represent the most important centers in the kitchen. To have the kitchenette ergonomically designed, it is needed to take into account the availability, clarity and also the details and sharp edges.
If you plan the reconstruction of your current kitchenette, or if you plan to buy the new one, respect the layout based on the triangle. You will ensure effective usage of the space without unnecessary moving. The triangle in the kitchen is not a new trend and it is not a whim of the designers. It is a timeless ergonomic lesson, which was firstly used by Henry Ford in his factory, so that the workers could work as effective as possible.
