ART & DECORATION
That wall torn down on a Saturday morning, the dust still hanging in the air, and suddenly — the light. That's often how it begins, an idea for an open kitchen to the living room that kicks off with a jackhammer and ends with a long question: now, how do we make it look like something? Because opening up the space is the easy part. What truly demands care is making two functionally opposite worlds coexist — one where you cook, the other where you unwind — without the result looking like a showroom apartment with no soul. This guide gives you concrete answers, from Scandinavian style to industrial loft, with a particular focus on what's too often overlooked: wall decor as a unifying element.
Why choose an open kitchen to the living room?
Before looking for inspiration, let's be honest about what you gain — and what you accept to manage.
The advantages of a unified living space
Natural light, first of all. When the two rooms communicate freely, it flows through the apartment unobstructed, turning even a modestly sized flat into something that breathes. The easy circulation also changes daily life: no more juggling doors when carrying a hot dish, no isolation for the person cooking while others watch a film. Conviviality isn't a marketing argument here — it's a physical reality. We talk, we share, we're together effortlessly.
Visually, the sense of volume is immediate. Two 15 m² rooms become a 30 m² space readable at a single glance. This is especially valuable in Parisian flats or townhouses where every square metre counts.
The constraints to anticipate before getting started
Let's be direct: cooking smells will circulate. A powerful extractor hood (minimum 600 m³/h for an open space) is not a luxury, it's an absolute necessity. Noise too — the hood, the dishwasher, the utensils — makes its way into the living room. And visible storage becomes a permanent aesthetic decision: open shelving, a cluttered island, crowded worktops, all of it is seen from the sofa.
Before knocking down a partition, check that it isn't load-bearing. If it is, a structural engineering study is mandatory. For a non-load-bearing partition, no administrative procedure is required in most cases — but check with your building management if you are in a co-ownership.
How to define the kitchen and living room without a partition?
The space is open, but that doesn't mean it should be undifferentiated. The invisible boundary between the two zones is precisely what gives the whole its structure.
The central island and the glass partition: trendy separators
The central island remains the most effective and elegant solution. It marks the boundary between the two spaces without ever closing them off. You sit there to have breakfast on the living room side, you prepare meals on the kitchen side. A Calacatta marble or oiled solid oak worktop acts as a functional sculpture at the heart of the room.
The interior glass partition, on the other hand, plays a more ambiguous role — it separates visually while letting light through. It's the ideal choice when you want to keep a slight distinction between the spaces (for acoustics, in particular) without sacrificing brightness. In matt black steel with clear glass panes, it brings an immediately recognisable industrial touch.
Changing the floor covering is another often underrated technique: large-format tiles on the kitchen side, oak parquet on the living room side. The transition reads naturally, with no physical obstacle at all.
Wall decor as a dividing line
This is where many people miss something important. A large painting placed on the side wall of the living room, at the junction of the two spaces, creates a powerful visual line. It says: here, this is the living room. No partition, no extra furniture, just the strength of the wall composition.
A well-chosen painting doesn't merely decorate a wall — it organises a space. In an open kitchen to the living room, it's what decides where one ends and the other begins.
The key is that they must be present enough to hold their own in the overall reading of the room.

Here are the combinations that really work — tested, coherent, and directly applicable.
Scandinavian style: light wood, white and nature paintings
The Scandinavian style is probably the most suited to open spaces, because it relies on a restricted colour palette that naturally unifies the zones. Ash or pine wood for the kitchen fronts, off-white walls, natural linen textiles on the living room side. Morning light caressing these pale surfaces creates something almost Japanese in its sobriety.
For the walls, favour botanical works — a blossoming cherry branch on an ivory background, a composition of fig leaves in fine line — or pared-back landscapes: a birch forest in the mist, a Norwegian coast in winter. These themes reinforce the connection to nature at the heart of Nordic aesthetics, and their soft palette (sage green, pale terracotta, grey blue) blends effortlessly into both spaces.
Industrial style: concrete, metal and urban art
The industrial style embraces its contradictions: the kitchen becomes a laboratory, the living room a workshop. Waxed concrete on the floors, kitchen fronts in brushed steel or anthracite-stained wood, aged brass pendant lights. It's a world with character — and it claims it.
The wall artworks that fit best are graphic, high-contrast, sometimes provocative. A large-format black and white urban photograph, a geometric screen print with hard lines, or a street art-inspired piece with blocks of vivid colour on a dark background. Exposed brick, if there is any, can itself become the painting.
In an industrial style, avoid artworks that are too "soft" or floral — they create a dissonance that weakens the whole. Stay within graphic, abstract or photographic registers with strong contrast.
For other styles — bohemian with its macramé, burnt ochres and textured artworks; minimalist with its large monochrome formats; modern with its abstract compositions in bold colours — the principle remains the same: choose artworks that speak the same chromatic language as the space, and position them where they structure as much as they decorate.

Choosing the right wall art to unify kitchen and living room
The question isn't "which painting is beautiful?" but "which painting does the job?".
What size painting for a large kitchen-living room wall?
Basic rule: in an open space, small formats get lost. A 40×50 cm painting on a 3-metre-wide wall is a timid vignette in a large void. For a main living room wall, aim for at least 80×100 cm.
It works particularly well in open spaces where you want to occupy the wall without overwhelming it.
Harmonising colours between the kitchen and living room
This is the most technical and decisive point. An artwork that picks up two or three shades present in each of the spaces automatically becomes a visual bridge between them. If your kitchen has sage green fronts and your living room a terracotta velvet sofa, look for an artwork containing both colours — even in different proportions, even abstractly.
The artwork's colour palette must respond to both spaces, not just one. That's what turns a decorative painting into an architecturally coherent element.

2025 trends: the open kitchen to the living room reinvented
The all-white look of the 2010s is definitively behind us. In 2025, open spaces are warming up: terracotta, ochre, bottle green, midnight blue. Natural materials are making a strong comeback — travertine, rattan, hammered brass, untreated solid wood. Wall art becomes a statement: no more timid small compositions, but works that truly occupy the space and assert their presence.
Architectural lighting also plays a growing role in delineating zones: adjustable spotlights above the island, a low pendant over the dining table, wall sconces on the living room side. Each zone has its own luminous signature, creating a subtle distinction without any partition.
Bohemian decor is enjoying a notable comeback, with its layering of textures, warm-toned artworks and mixed wall compositions (painting + plant + object). It's a style that forgives imperfections and ages well — two precious qualities in a space that is really used.

How to avoid cooking smells in the living room in an open space?
An extractor hood with a flow rate of at least 600 m³/h is essential — and it must be properly vented outside, not recirculating. Complement it with a few air-purifying plants (pothos, chlorophytum) and good cross-ventilation. Cooking smells in an open space are mostly a problem of an undersized hood.
What wall decor to choose for a small kitchen open to the living room?
Counterintuitively, a single large format is often more effective than several small ones. It visually enlarges the space by creating a strong focal point. Favour clear compositions with distant horizons (seascape, forest in perspective) that give the wall depth.
Do you need a building permit to open your kitchen onto the living room?
If the partition wall is not load-bearing: no, no procedure is required in a detached house. In a co-ownership building, check the building's rules — some management committees require a work declaration. If the wall is load-bearing, a structural engineering study is mandatory before any work, and a preliminary declaration may be required.
How do you create a cohesive atmosphere between a kitchen and a living room with different styles?
Three levers work well together: a shared color palette (even two or three common tones are enough), a material repeated in both spaces (oak wood flooring in the living room and on the kitchen facades, for example), and a central artwork whose composition brings both worlds together. This last point is often the quickest to implement.
An open-plan space deserves carefully chosen decor
We always come back to the same observation: knocking down a wall takes ten minutes of work (well, a few hours). Making sure the resulting space is coherent, lively, and truly beautiful is the real project. The success of an open-plan kitchen idea depends as much on functional choices (the island, the flooring, the lighting) as on overall decorative coherence. And in this equation, the wall painting is the unifying element that is almost always underestimated, until the moment it is hung and the entire space suddenly falls into place.
If you are looking for the artwork that will do this job in your space, the Walensky-shop.fr collection offers paintings designed for contemporary interiors, in formats suited to large living room walls and open-plan spaces. The empty wall that has been taunting you since you moved in deserves better.
