Getting the kitchen layout right matters more than any worktop or paint colour, because layout is what you live with every time you cook. It decides how far you walk between the sink, hob and fridge, how many people can work in the room at once, and whether the space feels generous or cramped. Before choosing units or appliances, it pays to settle the shape of the room, and the five layouts below (galley, L-shaped, U-shaped, island and open-plan) cover almost every UK kitchen. This guide explains how each one works, where it suits and the pitfalls to avoid.
The kitchen work triangle
Most good layouts still start from the work triangle: the path between the three points you use most, the sink, the hob and the fridge. Keep those three within easy reach of one another, without a walkway or an island cutting across the route, and the kitchen feels efficient. As a rough guide, no leg of the triangle should be so short that the space feels tight or so long that you are trekking between tasks. In larger open-plan rooms, designers increasingly think in zones (prep, cooking, washing) rather than a strict triangle, but the principle is the same: keep the things you use together close together.
Galley kitchen layout
A galley has two runs of units facing each other along a corridor. It is the most space-efficient layout and a favourite for narrow rooms and terraced houses. With the sink and hob on one run and the fridge on the other, the work triangle is tight and quick. Leave at least around 1.2 metres between the two runs so drawers and appliance doors can open and two people can pass. The main downside is that a galley with a through route at both ends becomes a thoroughfare, so where possible keep one end closed to protect the working zone.
L-shaped kitchen layout
An L-shape runs units along two adjoining walls, leaving the rest of the room open. It is one of the most flexible layouts, works in small and large rooms alike, and leaves space for a table or, in a bigger room, an island. The corner is the one detail to plan carefully: a carousel, a magic-corner pull-out or a diagonal unit stops that space becoming a dead zone. L-shapes suit open-plan living because the working kitchen sits neatly in a corner while the rest of the room stays free.
U-shaped kitchen layout
A U-shape wraps units around three walls, giving the most worktop and storage of any layout and an excellent work triangle. It suits medium to large square rooms and keen cooks who want everything within reach. The risk is that it can feel enclosed, so in a smaller room consider leaving one upper run as open shelving or a window wall to keep it light. Allow enough clear floor in the middle, ideally around 1.2 metres or more, so more than one person can work without collisions.
Island and peninsula layouts
An island is a freestanding run of units in the middle of the room, and it is the layout most people aspire to. It adds worktop, storage and often a hob or sink, and it gives a natural spot to sit and socialise while someone cooks. Islands need space, though: allow roughly a metre of clear floor all around so doors and drawers open and people can pass. If the room is too narrow for an island, a peninsula, an island attached at one end, delivers much of the benefit in less space. Running services such as water, waste or electrics to an island adds cost, so plan those early.
Single-wall and broken-plan layouts
Two more layouts are worth knowing. A single-wall (or one-wall) kitchen puts everything along one run, which suits studios, small flats and narrow open-plan rooms where a second run would crowd the space. The trade-off is a stretched work triangle, so keep the run tight and consider a slim island opposite for extra worktop. Broken-plan is the current alternative to fully open-plan: instead of one big room, the kitchen is loosely separated from living space by a half-height wall, a change in floor level, glazed partitions or a run of shelving. It keeps the light and sociability of open-plan while giving some separation from cooking noise and smells, which many households now prefer to a single undivided room.
Open-plan kitchen diner
Knocking the kitchen through into a dining or living space is one of the most popular home improvements in the UK, creating a single sociable room. It usually combines an L-shape or island with a dining and seating zone. Two things need planning from the outset. First, removing an internal or load-bearing wall is structural work that needs a steel beam and building regulations approval; the Planning Portal guidance on removing internal walls explains when approval is required. Second, cooking smells and noise travel in an open-plan room, so a good extractor and some acoustic thought make the difference between a room that works and one you regret opening up.
Choosing the right layout for your space
Start with the room you have, not the layout you have seen online. Measure the space, mark the positions of windows, doors, the boiler and existing services, and note where natural light falls. A narrow room points to a galley or single run; a square room suits a U-shape; an open-plan extension is made for an island. Think about how many people cook at once and whether you want to seat guests while you do. If the project involves moving walls, plumbing or electrics, it is worth getting a designer or builder involved early.

Frequently asked questions
What is the most efficient kitchen layout?
The galley is usually the most space-efficient because two facing runs keep the sink, hob and fridge close together. For larger rooms, a U-shape offers the best balance of storage and an efficient work triangle.
How much space do you need for a kitchen island?
Allow about a metre of clear floor on every side of an island so drawers and appliance doors open freely and people can move past. As a rough minimum, the room usually needs to be at least 3.5 to 4 metres wide before an island works comfortably.
Do I need planning permission to change my kitchen layout?
Refitting a kitchen in the same room does not need planning permission. Removing a load-bearing wall to open the space up needs building regulations approval and a structural beam, and an extension to enlarge the kitchen may need planning permission.
What is the ideal gap between kitchen units?
Leave at least around 1.2 metres of clear floor between facing runs of units or between an island and the surrounding cabinets. That lets doors and drawers open fully and allows two people to work or pass at the same time.
Which kitchen layout is best for a small kitchen?
A galley or a single-run (one-wall) layout makes the most of a small or narrow room. An L-shape also works well and frees a corner for a compact table, keeping the space feeling open.
