Open-plan kitchen: everything you need to decide before knocking down that wall

Opening the kitchen to the living room is not just a renovation decision. It's a decision about how you want to live in your home.

When it works well, the kitchen ceases to be a separate space and becomes part of the daily rhythm; you cook without disappearing, you are with those in the living room, and light flows through the space from one end to the other. When not well-planned, the result is a cluttered space where smells and noise invade the living room, and storage is never enough.

The difference between the two almost always lies in what is decided before knocking down the wall.

Not all kitchens benefit from opening up to the living room, and it's worth asking yourself this question before starting.

An open kitchen works well when there is enough space for both uses to coexist without getting in each other's way, when the orientation allows natural light to circulate, and when the person living in the house cooks in a way that doesn't generate too much visible mess.

There are cases where a partial opening, a window between the kitchen and living room, a peninsula that separates without enclosing, a tall piece of furniture that defines without blocking, provides more than a total opening. The question is not whether to open or not. It's how much to open and how.

Once you've decided that opening up the space makes sense, the layout is the first structural decision.

L-shapedis the most versatile for open-plan kitchens. It utilizes corners to gain worktop space and storage, and keeps the central axis clear for movement. It works well when you want a clear visual separation between the kitchen and living room without closing anything off.

With a peninsulasolves several issues at once: it defines areas, adds worktop space, and creates an informal gathering point. It can function as a breakfast bar, a second desk, or a spot where someone can sit while another person cooks. It requires less space than an island and doesn't need water or electrical installations in the floor, which significantly simplifies the construction.

With an islandoffers more flexibility and encourages interaction; you cook facing the space, connected to whoever is on the other side. It requires more square footage for movement: a minimum of 90–100 cm of clear passage on all sides, ideally 120 cm so that two people can move at the same time. If the island is going to include a sink or hob, water and electrical installations in the floor must be planned before construction begins.

An open kitchen with poorly resolved movement becomes a bottleneck.

The work triangle, the distance between the sink, hob, and refrigerator, must allow for comfortable movement between the three points without crossing paths with those entering or exiting. In L-shaped kitchens, the three points are usually distributed between the two walls. In kitchens with a peninsula or island, one of them can be integrated into the central element.

What to avoid: the walkway to the living room coinciding with the main work area. When someone enters to get something from the refrigerator and another person is cooking on the hob, the two cannot be in the same place without getting in each other's way.

Appliances: integration or contrast

Appliances: integration or contrast

In an open-plan kitchen, appliances are visible from the living room. This changes how we need to think about them.

Integration—paneled dishwashers, refrigerators with matching fronts, extractor hoods integrated into wall cabinets—maintains visual continuity and makes the kitchen feel like a piece of furniture, not just a collection of appliances. This option contributes the most to a natural transition between the kitchen and the living room.

The extractor hood deserves special attention. A powerful extractor reduces odors that spread to the living room. An integrated or ceiling-mounted hood can do this without becoming the most visible element in the space.

Small appliances—toasters, blenders, air fryers—are another point to address. In an open-plan kitchen, what's on the countertop is visible from the living room. Storing them when not in use, or reserving a specific spot for the appliance used multiple times a day, significantly changes the overall perception.

Storage: enough without overfilling

One of the most common concerns in open-plan kitchens is how to have enough storage without making the space feel cluttered.

Concentrating tall units on a single wall frees up the view and expands the perception of space. What is lost in tall units can be compensated for with well-organized deep drawers in the lower part, with storage in the island or peninsula, and with internal systems that utilize every centimeter without needing to add more modules.

There's a practical rule that works well in open-plan kitchens: always leave more surface area clear than occupied. A clear countertop not only looks tidier, but it's also more comfortable for cooking and easier to clean. An empty sink immediately conveys cleanliness from the living room. An island without accumulated items makes the whole space seem larger.

The storage that works in an open-plan kitchen is one that has a place for everything, and makes hiding it when guests arrive a matter of seconds, not minutes.

What needs to be settled before starting the work

Opening a kitchen to the living room involves decisions that cannot be made once construction has begun.

If the island or peninsula will have a sink, hob, or electrical outlets, the installations in the floor must be planned before laying the flooring. If the kitchen is to be visually integrated with the living room, the finish of the fronts must be considered along with the rest of the space, not afterwards. If appliances are to be integrated, you need to know which models before designing the furniture that will house them.
