Kitchen with island or peninsula: which one fits best in your open-plan space

An island or a peninsula are, in many cases, the same need met in two different ways: more work surface, a meeting point between the kitchen and the living room, and an element that gives structure to an open plan without closing it off.

The question isn't which is better. It's which best suits the space and how you live in it.

Island or peninsula: what each one solves and how they differ

An islandis a free-standing unit in the center of the kitchen, accessible from all sides. It allows you to work facing the living room, makes it easier for several people to be in the kitchen at the same time, and acts as a visual element that anchors the open space without dividing it.

A peninsulais connected to a wall or the existing furniture line on one of its sides. It offers extra surface area, defines the transition between the kitchen and living room, and can function as a bar, a breakfast area, or a second workspace, with less space and without the technical installation requirements that an island may entail.

Both add surface and connection. The difference lies in how much space they need and which problems they solve best.

When does an island make sense

An island works well when space truly allows for it, not when it technically fits, but when it allows for comfortable movement.

The minimum free passage on all sides is 90–100 cm. The comfortable standard is 120 cm, enough for two people to move around at the same time without getting in each other's way. Below 90 cm, an island stops being an improvement and becomes an obstacle: drawers don't open fully, the passage narrows, and the space feels smaller than before.

Beyond space, an island makes sense when it responds to a real use pattern. When people are habitually in the kitchen while cooking. When work surface is needed without wanting to expand the perimeter. When the kitchen needs to serve multiple purposes at once—cooking, working, having breakfast—and you want to be connected to the living room instead of turning your back.

If the island is going to include a sink, hob, or electrical outlets, installations must be planned in the floor before laying the pavement, and the island must be anchored to the floor. These decisions cannot be left for later.

A peninsula provides many of the same benefits as an island – surface area, visual separation, and a meeting point – but with less space and technical complexity.

Being connected to the wall on one side, it only needs free passage on three sides instead of four. This makes it viable in layouts where an island would not allow for sufficient circulation. And since it's not freestanding, it avoids the requirements for floor anchoring and simplifies installations if it doesn't include a cooktop or sink.

It works especially well in L-shaped kitchens where one arm extends into the living room, creating a natural transition between the two spaces. Also, in linear kitchens where there isn't enough space to circulate around a central element, but there is room to add an overhang at the end of the cabinet run.

What a peninsula doesn't provide is access from all sides; there's always one closed side. In kitchens where two people cook at the same time and need to move freely around the central element, that difference is noticeable.

How to decide between island and peninsula before discussing distribution

How to decide between island and peninsula before discussing distribution

There are two questions that help guide the decision before speaking with anyone from distribution.

The first: how much free space is left after placing the central element? If an island leaves less than 100 cm of clearance anywhere, a peninsula is the most sensible option, or even an extended countertop with an overhang, which achieves some of the same effect without taking up central space.

The second: what does that element need to do? If the answer is primarily to add workspace and create a visual boundary between the kitchen and living room, a peninsula solves this well. If the answer includes allowing several people to move around, cook from different sides, or have an integrated hob or sink, an island makes more sense, provided there is truly enough space.
