What Is the Best Fireplace for an Open-Plan Kitchen-Living Room?

Open-plan living has become the default layout for new-build and renovated UK homes — and it's easy to see why. Knocking through walls creates space, light, and a sense of togetherness that separate rooms simply can't match. But it also creates a design challenge that catches many homeowners off guard: where does the fireplace go? In a traditional living room, the chimney breast or a feature wall provides an obvious focal point. In an open-plan kitchen-living room, that natural focal point is often missing entirely. Choosing the right fireplace for this kind of space means thinking differently about placement, fuel type, and the role the fire actually plays in the room.

Why Open-Plan Spaces Need a Different Approach

A conventional living room is essentially a contained box. The fireplace sits on one wall, the furniture faces it, and the layout more or less arranges itself. An open-plan kitchen-diner changes that equation. The space is larger, the sight-lines are longer, and there may be no single wall that dominates. Cooking, dining, and relaxing all happen in one continuous area, and a fireplace that works beautifully in a 4 × 5 metre room can look lost in a space twice that size.

The trick is to think of the fireplace less as something that goes on a wall and more as something that defines where the living area begins. A well-chosen fire can ground the lounge zone, give your eye somewhere to rest, and create a sense of warmth — both literal and psychological — in a space that might otherwise feel flat or overly functional.

Placement Options Worth Considering

In an open-plan layout, you generally have three choices for where to position a fireplace:

A feature wall or media wall. This is the most common approach and the easiest to execute. A long, linear fire set into a dedicated wall — often alongside a television — creates a clear focal point for the living area. It works especially well if the wall separates the kitchen from the lounge visually, even without dividing the space physically.

A dividing wall or peninsula. If you have a half-height or structural wall between zones, a see-through or double-sided fireplace can turn it into a genuine design feature. The fire becomes visible from both the kitchen and the living area, creating a shared focal point that subtly defines each zone. This approach is increasingly popular in UK renovations where load-bearing walls can't be fully removed.

A freestanding or island installation. Less common but striking when done well. A freestanding fire positioned centrally can become the visual heart of the room. This works best in larger open-plan spaces where there's enough floor area to let the fire breathe without cluttering the layout.

Choosing the Right Fuel Type

The fuel type matters more in an open-plan space than in a closed room, because the fireplace has to work within a multifunctional environment — somewhere you cook, eat, and relax. Here's how the main options compare.

Electric Fireplaces

Electric fires are the simplest option to install and the most flexible in terms of placement. They don't produce combustion byproducts, so there's no need for ventilation — a significant advantage in a kitchen-living space where air quality matters. Modern LED flame effects have improved enormously, and wide-format electric fires suit the proportions of a large open-plan wall particularly well. If you're after visual impact without the commitment of a fuel-burning installation, browse our built-in electric fires to see how a recessed design can anchor a feature wall.

Bioethanol Fireplaces

Bioethanol fires produce a real flame with no chimney or flue required — which makes them a strong option for open-plan spaces where running a flue would be impractical or prohibitively expensive. Standard manual bioethanol burners are straightforward and relatively affordable, but for open-plan living, the smart bioethanol category is where things get interesting.

Smart bioethanol fireplaces — like the Neverdark and SF Eco-Luxe range available through LUXERGY — use vapour combustion technology. Rather than burning liquid fuel directly, they heat bioethanol to the point where it releases a vapour, and the vapour is what ignites. The result is a clean, controllable flame with no smoke, no soot, and no lingering smell. In a kitchen-living room, that last point matters: nobody wants their sofa absorbing cooking odours and fireplace fumes at the same time.

The Neverdark built-in models also come with fully insulated Thermobox enclosures, which means the fire can be installed safely into standard walls, cabinetry, or even directly beneath a mounted television. For a see-through installation in a dividing wall, a Thermobox with glass on both sides turns a structural partition into a striking architectural feature.

Water Vapour Fireplaces

Water vapour fires produce a flame effect using ultrasonic mist and LED light — no real combustion at all. They're completely safe, produce no heat, and can be installed almost anywhere. They're an excellent choice if you want the visual warmth of a fire in a space where actual heat output isn't needed — for example, in an already well-heated kitchen-diner where you simply want ambience.

Creating a Sense of Hearth in a Large Space

One of the underrated challenges of open-plan living is that the space can feel too open — comfortable enough for daily life but lacking the sense of intimacy that a cosy evening calls for. A fireplace solves this in a way that furniture arrangement alone cannot. It creates a gravitational pull: somewhere the eye is drawn, somewhere people naturally gather.

A few principles help make this work:

Scale matters. A small fire on a large wall looks like an afterthought. In open-plan spaces, wider formats — 90 cm, 120 cm, or longer — tend to feel right because they match the proportions of the room. Linear fires, which run horizontally rather than presenting a traditional square flame bed, suit contemporary open-plan interiors particularly well.

Height and position. In a kitchen-living room, the fire is often viewed from a standing position in the kitchen as well as a seated position on the sofa. Mounting the fire slightly lower than you might in a dedicated lounge — roughly 40 to 60 cm from floor level — ensures it works from both vantage points.

Surrounding materials. The area around the fire does as much work as the fire itself. A recessed fire set into a smooth, floor-to-ceiling panel in stone, concrete, or dark-toned plaster creates a visual anchor that holds its own against the activity of a busy kitchen on the other side of the room.

Which Fireplace Suits Your Space?

There's no single right answer — it depends on your layout, your budget, and how much installation work you're prepared to take on. As a practical starting point:

If you want ease of installation and no ongoing fuel costs, an electric fire is the path of least resistance. If you want a real flame with the flexibility to install anywhere — including inside custom joinery or a media wall — a smart bioethanol fire with an insulated enclosure gives you that freedom. And if you want pure visual atmosphere with zero heat output, a water vapour fire is hard to beat.

At LUXERGY, every fireplace is selected with exactly these kinds of decisions in mind — fires that work in real homes, not just in showroom settings.
