An open-plan kitchen can completely transform a flat: it brings in light, opens up the view and turns meal preparation into a shared activity. But knowing how to design a functional open-plan kitchen is not simply a matter of knocking down a partition wall. The difference between a light-filled space and an uncomfortable room lies in carefully planning circulation routes, installations, storage, acoustics and visual boundaries.

In renovations of city flats, penthouses and lofts, one idea keeps coming up: the kitchen must be part of social life without imposing its more technical aspects. It must be able to accommodate a casual dinner, a hectic morning and intensive daily use without the living room looking like a cluttered extension of the worktop.

An open-plan kitchen begins before a single partition wall is moved

Opening up the kitchen requires a thorough analysis of the existing floor plan. The location of the drainage pipes, how light enters, which walls are load-bearing, and the flow of movement all shape the project from the outset. Forcing an island into the centre of a small room, for example, may leave less usable space than a well-designed separate kitchen.

The first decision is not about aesthetics, but about practical use. It is important to establish who does the cooking, how often, how many people use the space at once, and what relationship you want with the dining room and living room. A couple who cook every day need a different workflow to that of a home intended for frequent gatherings or an investment flat.

The degree of openness also matters. Not all kitchens need to be completely open-plan. A partially open layout, a glazed front or a peninsula can maintain visual connection and natural light whilst controlling odours, noise and views into the work area. The best approach depends on the property itself, not on a trend.

How to design a functional open-plan kitchen based on circulation

A kitchen works well when movements are short, clear and do not interfere with those sitting or chatting. The route between the fridge, washing-up area, hob and preparation surface should be fluid. Rather than applying a rigid formula, the aim is to avoid unnecessary crossings: it is not ideal for someone to have to cross the main passageway to open the dishwasher or access the larder.

In a linear layout, the usual sequence can be: storing, washing, preparing and cooking. This is a very effective solution for narrow flats, particularly when accompanied by a table or a light-weight island that connects to the living room. In more spacious kitchens, an L-shaped layout allows you to maximise worktop space and concentrate work on two sides without cluttering the space.

The island deserves special attention. It can be used for cooking, eating, storage or defining different areas, but it does not necessarily have to fulfil all these functions at once. An island with a hob requires a well-planned extractor fan and sufficient worktop space on both sides. If it incorporates a sink, you’ll need to allow for the necessary plumbing and a more carefully considered layout. When the main focus is on socialising, a peninsula with stools may be more proportionate and leave more space for moving around.

The space around an island must allow you to open drawers, load the dishwasher and move about without obstruction. In a compact home, sacrificing a few centimetres of worktop space to gain more comfortable passage is usually a wise decision. A sense of spaciousness comes not only from the square metres but also from the absence of obstacles.

Tackling the technical aspects without compromising on aesthetics

Odours are one of the most common arguments against open-plan kitchens, and rightly so. A good extractor hood alone cannot compensate for an incorrectly sized extraction system or poorly routed ductwork. The design must take into account, right from the start, the available flue outlet, the required power and the noise level of the equipment. A recirculation system may be a viable option in certain cases, but it requires suitable filters and regular maintenance.

Noise is also a design consideration. Dishwashers, fridges, cooker hoods and small appliances are all visible from the living area. Choosing quiet appliances and incorporating built-in panelling improves the day-to-day experience. In projects where the kitchen shares space with a TV room or a heavily used dining area, this consideration carries as much weight as the finish of the cupboard doors.

Installations must be co-ordinated before ceilings and wall cladding are fitted. Electrical sockets for small appliances, task lighting, charging points and water connections require precise positioning. A visually uncluttered kitchen is not one with fewer requirements, but one that has planned for where these needs arise.

Defining spaces without disrupting continuity

An open-plan kitchen needs its own identity, but it must interact with the rest of the home. Materials help to strike that balance. A mineral worktop, natural wood or steel can lend character to the kitchen area, whilst continuous flooring extends the sense of space into the living room. There is no one-size-fits-all combination: the key lies in deciding which elements unify the space and which mark the transition.

The size of the wall units is another key consideration. In compact spaces, a full wall of tall units can accommodate a fridge, oven and larder, but may also create an overly imposing presence. Blending them with the wall colour, setting them back or combining them with base units helps maintain order without visually closing off the room.

In several of FFWD’s residential projects, bespoke furniture is conceived as interior architecture. A panel can conceal a larder, extend to form a bookcase or incorporate a bench next to the dining area. This continuity avoids the feeling of having placed a kitchen in the living room and gives the whole space a more serene feel.

Lighting helps to define the boundaries. The worktop requires direct, even lighting, free from shadows cast by the person cooking. The dining area benefits from warmer, focused lighting, whilst indirect lighting on shelves, skirting boards or ceilings can enhance evening use. Separating the lighting circuits allows each area to have its own atmosphere without fragmenting the space.

Storage: organisation must be built in

In a closed-off kitchen, certain items can be kept out of sight. In an open-plan kitchen, every object on display affects the perception of the living room. That is why storage cannot be an afterthought or merely a matter of adding cupboards wherever there is space.

Storage capacity must be tailored to real-life habits: everyday crockery, bulky kitchenware, recycling, food supplies and small appliances. A well-organised larder unit can free up worktop space; a dedicated unit for the coffee machine and toaster prevents these appliances from becoming a permanent fixture. Deep drawers are usually more practical than base units with shelves, especially for heavy pots and utensils.

It’s also a good idea to plan a prep area next to the fridge, the oven and the hob. These are small touches, but they make all the difference to day-to-day convenience. A clutter-free worktop isn’t maintained through sheer willpower: it stays that way when every item has its own designated place.

Choosing materials for shared use

Visual continuity should not lead to the choice of materials that lack durability. An open-plan kitchen is more exposed to stains, knocks and changes in light, as it shares space with the living areas. Worktops made of sintered stone, quartz or natural stone offer different performance characteristics and aesthetic qualities. The choice depends on the intended use, the level of maintenance required and the overall character of the project.

Very matt surfaces conceal certain fingerprints, but may show grease marks more clearly if not cleaned regularly. Wood brings warmth and depth, although it should be reserved for suitable areas or properly protected. In family homes, edging, handles and fittings warrant a particularly practical approach. Sophistication is not at odds with durability.

Flooring presents a similar decision. Using the same flooring in the kitchen and living room enhances the sense of space, whilst a different floor covering can help define the work area. In both cases, the priority is that it withstands water, frequent cleaning and heavy footfall. A change of material only works if it serves a functional purpose; it should not be used merely as a decorative feature.

When an open-plan kitchen isn’t the best solution

An open-plan kitchen is not essential for creating a contemporary home. If the homeowner cooks frequently, if ventilation is limited, or if the living room is used as a space for relaxation and work, a separate or semi-open kitchen may offer better results. A sliding glass door, for example, allows the space to be closed off when necessary without losing light or the sense of connection.

In the restaurant and hospitality sectors, this issue takes on a whole new dimension. An open-plan kitchen can reinforce a brand experience, but it demands flawless operations, sound control and a consistently polished working environment. The lesson also applies to the domestic sphere: opening up a space means revealing how it functions.

A good open-plan kitchen does not seek to appear larger at any cost. It seeks to adapt the space to a specific way of living. When layout, technology and materials are considered as a single decision, the kitchen ceases to be a mere backdrop and becomes the place where the home is organised, shared and enjoyed every day.
