How to Plan Kitchen Units for Small, Medium and Large Spaces

Key takeaways

• Start with the working triangle (hob, sink, fridge) and main walkways, then fit units around those rather than the other way round.
• Small kitchens usually work best with 3–5 base units, 2–4 wall units and a single tall unit; larger rooms can comfortably handle more tall storage without feeling boxed in.
• Use smart corner storage, such as a 270-degree corner carousel, to make awkward spaces accessible instead of dead zones.
• Always position dishwashers and bins near the sink and make sure appliance doors can open fully without clashing.
• To keep the room feeling open, balance tall units with stretches of worktop, shallower wall units and, in some cases, open shelving or a dresser.

Why this category matters

Your choice and placement of kitchen units directly affects how you cook, clean and socialise in the space. The same room size can feel either cramped or generous depending on how base, wall and tall units are distributed. Well-planned units provide enough storage for food, cookware and small appliances while keeping what you use most often within easy reach. Poorly planned units force you to dig through back corners, constantly shift items around and fight for every spare inch of worktop.

Kitchen units also control how open or enclosed a room feels. Continuous wall units around all four sides can make even a large kitchen feel tunnel-like, while a thoughtful mix of tall larders, wall cabinets and open stretches above worktops can make a compact galley feel lighter. This is particularly important in small and medium kitchens where visual space matters as much as physical storage.

From a budget perspective, units are usually one of the biggest costs in a kitchen project. It is worth spending time on the plan so you buy the right types and numbers from the outset. Understanding what each unit does – from corner carousels to deep pan drawers – allows you to spend where it genuinely improves day-to-day use and save where a simpler option will do the job just as well. Good planning can also reduce the number of complex fillers, infills and site modifications you need.

Finally, well-planned unit layouts help future-proof your kitchen. You may want to swap a freestanding fridge for an integrated one, add a microwave housing or upgrade worktops to something more premium such as an oak wood worktop. A sensible unit framework makes those changes easier without a full redesign.

How to choose

Before counting units, measure your room carefully, including doors, windows, radiators, alcoves and any structural nibs. Note where services such as gas, water and waste currently are and whether you are prepared to move them. Then decide on the broad layout type your room suits best: straight run, L-shaped, U-shaped, galley or a layout with an island or peninsula. That framework will dictate where your base and tall units can realistically go.

Next, map the working triangle: fridge, hob and sink. In a small galley this may become more of a working line, but the principle is the same – keep the main tasks within arm’s reach, with clear worktop either side of the hob and sink. Try to avoid putting the fridge at the far end of the room behind an island, or the oven in a corner where the door blocks the way. Once you have this triangle roughly in place, start blocking in base units to support it, followed by wall and tall units.

For storage planning, list what you need to house: food staples, pans, baking trays, small appliances, cleaning products and tableware. Deep drawers are excellent for pots, pans and Tupperware; standard base units with shelves work for lighter items and bulk food. Wall units are best for everyday crockery and glasses. Tall units can combine larder storage with appliance housing. Smart corner options such as a pull-out or corner carousel system can transform hard-to-reach spaces into practical, high-capacity storage.

It is also worth considering the visual balance of your units. In small kitchens, limit the number of solid wall units on long runs and consider a break with a shallower cabinet or a couple of open shelves, or even a dresser-style piece as discussed in more detail in the guide to alternatives to standard kitchen units. In larger kitchens, tall units can be grouped together to form a storage wall while leaving stretches of lower-level units and windows to keep things airy.

Planning units for small kitchens

In a compact kitchen (for example, a galley or a small L-shape), your aim is to maximise storage and worktop without blocking movement. A typical small layout might include 3–5 base units, 2–4 wall units and 1 tall unit. That could look like: a 600 mm oven housing, a 600 mm sink unit, one or two 600 mm drawer units and perhaps a 300–400 mm pull-out larder or bin unit. Above them, two double wall cabinets such as an 800 mm gloss wall cabinet can store crockery and food.

Small kitchens benefit enormously from corners that actually work. If you have an L-shape, using a carousel or swing-out fitting allows you to store heavier items like pans and mixers in the corner and still reach them easily. Galley kitchens, on the other hand, often work best if you avoid corners altogether and instead use straight runs of drawers and cupboards that are easy to access from a central walkway.

Try to keep tall units to one end or one wall so they do not visually narrow a tight room. A single full-height fridge-freezer or oven/larder stack is usually enough. Opposite that, run base units with wall cabinets or shelves only, ensuring at least 900–1,000 mm between facing runs so two people can pass without bumping into each other.

Planning units for medium kitchens

In a medium-sized kitchen, you have more flexibility to separate zones and include features like a small island or peninsula. A typical plan might include 6–9 base units, 4–6 wall units and 2–3 tall units. For example, you might build an L-shape around two walls with a tall fridge and oven housing at one end, then add a peninsula with base units and an overhang for stools.

This is the scale where grouping tall units together into a ‘bank’ works very well. You might place a tall larder, oven housing and integrated fridge-freezer side by side on a short wall, keeping the rest of the room to base and wall units with plenty of worktop. Corner solutions become more of a choice than a necessity – you can use a carousel or ‘magic corner’ if you want maximum capacity, or simply block off the corner internally if you already have generous storage elsewhere.

Medium kitchens are also more forgiving of wall units, but it is still worth leaving at least one stretch – often above a sink or hob – with either a single row of cabinets or a combination of a cupboard and open shelves, to keep the room from feeling boxy. Your worktop choice becomes more noticeable at this size too; a continuous run of wood, stone or laminate can visually tie the units together and make the kitchen feel broader than it is.

Planning units for large kitchens

In a large space, the main challenge is preventing the kitchen from feeling scattered or echoey. Instead of simply adding more of everything, think in terms of zones: cooking, prep, washing-up, breakfast or drinks, and possibly a baking area. Each zone needs an appropriate mix of base, wall and tall units. You may end up with 10–16 base units, 6–10 wall units and 3–6 tall units depending on the architecture and whether you include a sizeable island.

Many large kitchens suit a long run of tall units along one wall, forming a ‘storage and appliances’ zone: tall larders, fridge-freezer, oven and microwave housings, possibly even a concealed utility cupboard. On the opposite wall or forming a U-shape, you can then have mainly base units, with carefully chosen wall cabinets or open shelves above. The island usually hosts either the hob or the sink with dishwashers and bins nearby, backed up by deep drawer units for pans and utensils.

Despite the extra space, you still need to respect the working triangle. It is surprisingly easy to create a plan where the fridge and ovens are on one side of a huge island and the sink and hob are on the other, forcing you to walk long distances for every task. Instead, build the triangle within a smaller part of the room and let secondary storage and display units sit further away.

Planning a galley kitchen

Galley kitchens – long, narrow rooms with two parallel runs – need especially careful unit planning. You will usually have 3–4 base units on each side, with or without matching wall units above. Aim to keep at least one side slightly ‘lighter’: perhaps base units with shelves above rather than full-height wall cabinets, or tall units only at one end rather than along the full length.

Place the sink and hob on the same side if possible, with the fridge at one end where it will not interrupt the main worktop. A dishwasher works well next to the sink but avoid placing it directly opposite another appliance; open doors facing each other can completely block the walkway. You can use slimline units (300–400 mm wide) at pinch points near doors to ease circulation while still gaining storage.

Before committing to a galley layout, mark out base unit depths and walkways on the floor with tape or cardboard. Stand in the ‘aisle’ and pretend to cook; you will quickly feel whether the space between runs is comfortable for your household.

Common mistakes

One of the most common mistakes is planning around the walls instead of around how you use the kitchen. Filling every bit of wall space with units may seem efficient, but it often leads to cluttered worktops and awkward access. For example, putting a tall unit immediately next to a corner can make both that corner and the tall cupboard hard to use. Instead, leave room for countertops near key appliances and keep corners either properly equipped with a carousel or completely avoided.

Another frequent error is ignoring appliance clearances. Ovens, dishwashers and fridge doors all need space to open without hitting other doors or handles. A dishwasher that blocks a doorway or a fridge that cannot open fully will be a daily irritation. Similarly, placing a hob hard against a tall unit or wall leaves no safe landing space for hot pans and may violate manufacturer guidelines.

People also underestimate the impact of tall units in small rooms. While a full bank of tall cupboards offers huge storage, it can overpower a compact kitchen if used on both sides or around every corner. The key is to concentrate tall units in one area and balance them with lower units and lighter wall storage elsewhere so the room still feels open. Open shelving or a dresser-style unit can help soften a tall run without sacrificing too much capacity.

Finally, corners are often treated as an afterthought, resulting in awkward dead spaces. Either commit to a proper corner solution – such as a carousel, swing-out shelves or a ‘magic corner’ system – or design your plan to avoid corners where possible, especially in tight galley kitchens. Half-used corner units quickly become graveyards for rarely used items, so it is worth investing thought – and sometimes a little extra budget – into making them truly functional.

Top kitchen unit planning options

While most of your units will come as part of a kitchen range, a few key components can dramatically improve how your layout works day to day. Below are three types of products that can help you maximise space, particularly in small and medium kitchens, while creating a more practical working environment.

These examples show how specialist corner storage, solid worktops and well-sized wall cabinets can slot into typical kitchen plans. They are not a complete list of everything you need, but they highlight features worth looking for when choosing units and fittings from any supplier.

Three-Quarter Corner Carousel

Corner units are notoriously difficult to access, especially in L-shaped kitchens. A three-quarter 270-degree carousel fitting turns that deep, dark corner into easily reachable storage. The rotating shelves bring items out towards you, so heavy pans, mixers or stacks of bowls can live in the corner without being lost at the back. This is particularly useful in small kitchens where every cupboard must earn its keep.

A quality corner carousel, such as the type used in a 270-degree corner unit system, usually offers a decent load capacity and smooth rotation. The main advantages are much improved access and the ability to keep the front of the kitchen looking clean and continuous, rather than having to break an L-shape into two short runs. The downside is that these mechanisms cost more than simple shelves and they slightly reduce the usable width of the cabinet compared with a plain box. However, for many layouts the gain in convenience outweighs the small loss in raw volume.

If your plan includes one or two corners and you are tight on space, allowing for a carousel in the design phase is wise. Check the diameter and hinge clearance so the doors can open without clashing with adjacent handles. You can then choose a compatible fitting such as a three-quarter corner carousel arrangement once the base unit size is confirmed.

Solid Oak Wood Worktop

Worktops are not units, but they have a huge impact on how your kitchen layout feels and functions. A solid oak worktop provides a continuous, warm surface that can visually tie together base units of varying sizes and help a small or medium kitchen feel more cohesive. The natural grain also softens the look of tall banks of units, especially in otherwise modern schemes.

A sized option like a solid oak wood worktop section can be useful when planning straight runs or compact peninsulas. The pros include the ability to cut and join pieces on site, repair light damage by sanding, and enjoy a surface that gains character over time. However, wood does require regular oiling and care around sinks and hobs to prevent water or heat damage. It is usually best for layouts where the main sink is well sealed and hot pans have a dedicated trivet or hob surround.

When planning unit positions, remember that wooden worktops are often around 620 mm deep, giving a little overhang beyond typical 560 mm-deep base units. This can be handy in slightly uneven rooms. If your design includes an island, you may opt for a wider piece to allow for breakfast seating on one side. A consistent material across different runs will help even a more complex combination of base and drawer units feel unified.

800 mm Gloss Wall Cabinet

Wall units are key to getting the right storage balance, particularly in small and medium kitchens where floor space is limited. An 800 mm-wide double wall cabinet offers a generous amount of storage without needing multiple narrow units, which can lead to a busier look. It is a practical size above a standard 600 mm base unit with a little extra overhang, or centred over a pair of narrower bases.

A unit similar to an 800 mm gloss wall cupboard is large enough to hold everyday plates, bowls and glasses while keeping them within easy reach above a dishwasher or sink. The gloss finish helps reflect light, which can be helpful in narrower galley layouts or north-facing rooms. On the downside, a solid block of glossy wall units can feel dominating if you use too many; it is often better to mix them with a shorter run, a glass-fronted cabinet or some open shelves.

When planning your unit layout, think about how many 800 mm wall cabinets you genuinely need and which walls can handle their visual weight. For example, two units over a 1.6 m stretch of worktop create a clean, symmetrical run in a small kitchen, while a row of three might be more appropriate over a longer prep area in a medium space. Because wall units are fixed relative to the base units below, finalise base positions first, then map wall cabinet sizes and heights to suit.

Conclusion

Planning kitchen units for small, medium and large spaces comes down to the same core principles: respect the working triangle, protect your walkways, and choose a mix of base, wall and tall units that supports how you actually cook and live. In a small kitchen, that may mean prioritising deep drawers and a single tall larder, aided by a smart corner carousel. In a larger room, it can mean zoning with a tall storage wall, an island and carefully placed wall cabinets that keep the room feeling open.

By thinking through what you need to store, how many people will use the kitchen and how you like to cook, you can create a layout that feels tailored rather than generic. Details like corner mechanisms, well-sized wall cabinets and continuous worktops – perhaps in a warm timber such as a solid oak work surface – help make everyday tasks smoother and the space more enjoyable.

Take time to sketch a few versions, test clearances and consider how you might adapt the layout in future. With a solid plan in place, choosing the specific units, finishes and fittings – from your base cabinets to a suitable corner carousel solution – becomes a far more confident and enjoyable process.
