Kitchen Layouts Explained: Galley, L-Shaped, U-Shaped and Island

Every great kitchen starts with the layout. It’s the decision that shapes how the room feels to cook in, where everyone gathers and, more than anything else, what the finished kitchen costs.

The right choice depends on the shape of your room, how many people cook at once and what else the space needs to do. In a narrow room, a galley is usually the most efficient. An L-shape suits most medium-sized and open-plan kitchens. A U-shape gives you the most worktop and storage in a squarer room. And an island works when there’s enough space to walk comfortably all the way around it.

Here’s how each one works, the space it needs and the kind of home it tends to suit.

Start With How You Use the Room

Before you choose a shape, it’s worth answering a few practical questions:

• Who cooks, and how often do two people cook at the same time?
• Does the kitchen need to seat people, and is that for everyday meals or the occasional drink?
• Is it a closed room, or open to a dining or living area?
• Where are the doors, windows and existing plumbing?
• How much storage do you need, and is there a larder or utility room elsewhere?

You’ll often find your answers rule out some layouts straight away.

The Working Triangle

Most kitchen planning still starts with the three busiest points in the room: the sink, the hob and the fridge. Keep them reasonably close together, without anyone having to walk around an obstacle to get between them, and the kitchen feels effortless to work in.

A widely used rule of thumb is that each side of this triangle should be roughly 1.2 to 2.7 metres long, with the total no more than about 8 metres. It’s a guide rather than a law. Larger open-plan kitchens often work better as a series of zones, for preparation, cooking, washing up and serving, but the principle of keeping the busiest tasks close together still holds.

The Simple Single-Wall Kitchen

Everything sits along one wall: units, appliances, sink and hob.

Works best in: studio flats, compact homes, and open-plan rooms where the kitchen needs to take up as little floor space as possible.

Why you’ll love it: it’s the simplest and usually the most affordable layout, and it leaves the rest of the room free.

Watch out for: limited worktop. A run of at least three metres makes a single-wall kitchen far more practical, and tall units add storage without taking floor space.

The Efficient Galley Kitchen

Two parallel runs of units facing each other, with a walkway between.

Works best in: narrow rooms, which is why galleys are so common in Victorian and Edwardian terraces and in many flats.

Why you’ll love it: there’s a reason professional kitchens use galleys. Everything is within a step or two, there’s plenty of worktop for the footprint, and not an inch of floor goes to waste.

Watch out for: the gap between the runs. Around 1.2 metres between the fronts of the units lets you open dishwasher and oven doors and still squeeze past. Much less and the room feels cramped; much more and you lose the very efficiency that makes a galley worthwhile. Putting the sink and hob on opposite runs means two people can work without bumping into each other.

The Versatile L-Shaped Kitchen

Units run along two adjoining walls, forming an L.

Works best in: medium-sized kitchens and kitchen-diners, especially where the open side of the room is used for a table or seating.

Why you’ll love it: it’s the most flexible layout of all. It creates a natural working triangle in the corner, keeps traffic away from the cooking zone and leaves floor space for dining. It also pairs beautifully with an island or a breakfast bar.

Watch out for: the corner. Without a good corner storage solution, the cupboard where the two runs meet becomes a black hole. Pull-out and swing-out mechanisms make that space genuinely usable.

The Generous U-Shaped Kitchen

Units run along three walls.

Works best in: squarer rooms where the kitchen is a dedicated space rather than part of an open-plan area.

Why you’ll love it: you get the most worktop and storage of any layout, with everything close at hand. It’s a favourite with keen cooks.

Watch out for: the width of the room. The space between the facing runs needs to be generous, ideally 1.2 to 1.5 metres, or the room starts to feel enclosed. Two corners means two corner solutions, and in a small room a U-shape can feel boxed in. Keeping one side lower, or opening it up as a breakfast bar, helps a great deal.

The Sociable Island Kitchen

A freestanding block of units in the middle of the room, usually combined with an L-shape or a single run.

Works best in: larger kitchens and open-plan kitchen-diners, where the island becomes the social centre of the room.

Why you’ll love it: extra worktop and storage, somewhere for people to sit and chat to whoever’s cooking, and a natural divide between the kitchen and living areas.

Watch out for: clearance. An island needs space to walk all the way around it. Around one metre on every side is a comfortable minimum, rising towards 1.2 metres where two people cook or where an oven or dishwasher door opens opposite. A cramped island is worse than no island at all. We cover the numbers in detail in our guide to how big a kitchen island should be.

The Space-Saving Peninsula

Like an island, but attached to a wall or the end of a run on one side.

Works best in: kitchens that aren’t quite big enough for a full island, or where the room needs a partial divide from a dining area.

Why you’ll love it: most of the benefits of an island, including seating and extra worktop, in less floor space.

Watch out for: creating a dead end. A peninsula should never block the route through the room.

The Rise of Broken-Plan Living

This newer approach sits somewhere between a closed kitchen and fully open-plan living. The main kitchen stays open to the living space, while the messier jobs move out of sight into a pantry, a scullery or a utility room next door. Partial walls, glazed screens, shelving and changes in floor level create zones without closing rooms off.

It’s ideal if you love the sociable feel of open-plan, but not the clutter and noise that come with it.

Matching the Layout to Your Home

The homes in our part of the country give some useful starting points:

• Victorian and Edwardian terraces, common around Bedford, Hitchin and St Albans, usually suit a galley or, with a side-return extension, an L-shape with an island.
• 1930s semis often gain a great deal by knocking the kitchen through to the old dining room and creating an L-shape with a breakfast bar.
• Newer homes on estates across Bedfordshire and Milton Keynes often have open-plan kitchen-diners that suit an island or peninsula.
• Period cottages and farmhouses, from the villages around Ashwell to the Chilterns, often call for a layout that works with chimney breasts, low ceilings and uneven walls rather than against them.

How Layout Shapes the Budget

Layout also has the biggest single effect on cost, because it decides how many units, how much worktop and how much plumbing and electrical work your kitchen needs. As a guide, our published ranges are £7,000 to £12,000 for a single-wall kitchen, £12,000 to £18,000 for an L-shape with a breakfast bar, and from £18,000 for an L-shape with an island and range cooker. Our kitchen price guide explains what’s included and what moves the figure.

Frequently Asked Questions

What is the most efficient kitchen layout?

For a single cook, a galley is usually the most efficient because everything is within a step or two. For most households, though, an L-shape offers the best balance of efficiency, flexibility and space for dining.

What is the smallest kitchen that can have an island?

As a rough guide, you need space for the island itself, at least around 600mm deep and 1,200mm long, plus about one metre of clear walkway on every side. If your room can’t give you that, a peninsula is usually the better option.

Is a galley kitchen better than an L-shaped kitchen?

Neither is better in itself. A galley is ideal for a narrow room and makes excellent use of the space, while an L-shape suits a wider room and leaves space for a table or island. In most cases, the shape of the room decides it for you.

Are U-shaped kitchens outdated?

Not at all. They remain one of the most practical layouts for a dedicated kitchen with plenty of storage. They’ve simply become less common because more homes now have open-plan kitchen-diners, which suit L-shapes and islands.

Can I change my kitchen layout?

Usually, yes. Moving the sink, hob or appliances is very common, although it adds plumbing, electrical and sometimes gas work. Removing a wall to create a bigger kitchen involves structural work and building control approval. A designer can tell you what’s practical for your room.
