One of the biggest considerations in a galley kitchen is guarding your sense of space. Being a typically long and skinny room, it can quickly become too heavy and the last thing you want is to feel like the walls are closing in.
In some galley kitchens, wall cabinetry definitely has a place – used sparingly. But the point is to not take it as a given and to be open-minded about keeping the walls and counter tops free. Yes, it means doing away with some storage space, but that can encourage you to have a bit of a clear-out and to be more disciplined with the things you really need to keep. It’s also an invitation to get a bit more creative with storage beneath the countertop – it needs to work as hard as it possibly can, especially if you only have enough square meterage for one run of cabinetry rather than two parallel lines.
When the walls are kept clean, the room opens up considerably, so much so that even a galley can end up feeling like one of the airiest rooms in the whole house.
