Just like the compact galley on ships, for which the layout is named, galley designs optimize space by packing in an abundance of storage and work area, making them ideal for small kitchens. If you're considering a galley layout or revamping one you have, here's what you need to know.
Enhance a closed-off kitchen wall. A galley kitchen closed off at one end can be a safer layout, because there's only one entrance, giving the cook greater awareness of others coming and going.
The clever use of the mirror in this compact kitchen is also worth noting; it creates the impression of a bigger space.
As already mentioned, losing the continuity of tall units in favor of wall units or shelving will help open up the space.
