Sketching Isn’t a Nice-to-Have: Why It’s Essential in Commercial Kitchen Design

Commercial kitchen design has never had more technology at its disposal. CAD, 3D modelling, photorealistic visualisation, and now AI tools that can spit out a layout in seconds.

So why do we still start so many of our projects with a pencil and a roll of tracing paper?

Because sketching isn’t about producing a pretty drawing. It is part of the problem-solving itself, and there’s a decent body of design research that backs that up.

Before a commercial kitchen layout becomes a CAD drawing, there are dozens, sometimes hundreds, of decisions to work through. How do chefs move through the space? Where does food come in, and where does waste go out? How do prep, cooking, storage and wash-up interact with each other? What does the menu actually demand of the equipment? Where are the pinch points, and what happens when service hits its busiest ten minutes?

Here’s why we think sketching still earns its place on every project.

1. It gets the problem out of your head

A commercial kitchen is a genuinely complicated operational system. At any one time you’re holding workflow, equipment, staff movement, food safety, storage, deliveries, waste, customer flow, services and the physical constraints of the building. All at once and all interacting.

Trying to manipulate that entirely in your head is hard going. Sketching gives it somewhere else to live. Instead of juggling every relationship simultaneously, we put it on paper, move the pieces around, and watch how they behave.

This isn’t just designer folklore, either. Research into design cognition and how designers think has looked closely at how external representations like sketches support problem-solving, and found that designers use them to develop ideas, not just record ones they’ve already had. The paper becomes a second workspace, doing some of the thinking alongside you.

2. It lets you see movement, not just placement

A kitchen layout is as much about what happens between the equipment as it is about where the equipment sits.

Where does a chef travel between the fridge, the prep bench and the cookline? How many times does someone cross the kitchen mid-service? Do clean and dirty routes cross paths they shouldn’t? Does the route from prep to cooking to pass make sense, or does someone spend half the shift walking back and forth?

Some consultants trace this quite literally, laying string or thread over a plan to map staff, food and waste journeys through the room. The resulting tangle can expose unnecessary travel and congestion almost instantly. We tend to do the same thing with a pencil and tracing paper: routes, arrows, relationships drawn straight over the layout as it develops.

There’s a real principle behind what looks like a fairly simple exercise. Once movement is visible, it becomes something you can examine, compare and change. A piece of equipment can look entirely sensible on a plan. Draw the journey someone has to make to reach it fifty times in a service, and it often stops looking sensible at all.

This sits within what’s sometimes called distributed, or external, cognition; the idea that string, tracing paper, post-its, physical models and sketches all function as tools that let a designer manipulate a complex problem outside their own head, rather than purely within it. So this isn’t really an argument for “hand-drawing over CAD.” It’s closer to: good designers reach for different representations depending on what kind of thinking the moment calls for. That’s a harder claim to write off as nostalgia.

3. You find solutions through sketching

This is probably the most important point, and the one that surprises people most.

There’s an assumption that a designer thinks of a solution, then draws it. In practice it runs both ways. You draw something, look at it, and notice something you hadn’t considered. You draw over it. That opens up another possibility, and before long you’re looking at a solution that didn’t exist when the pencil first touched the paper. The page gives the idea a visual form you can properly look at, not just hold as a vague picture in your head.

The architecture researcher Gabriela Goldschmidt has studied this closely, describing sketching as a form of visual reasoning. Her work with practising architects found that designers don’t only draw from mental images they already hold, but sketches also generate new mental images and ideas as they’re being made. The drawing isn’t simply the output of the thinking. It’s part of the thinking.

There is something more immersive about that process, too. Sketching asks you to look, adjust, compare and respond to a problem. It gives you a different mental gear from simply reading a list of requirements or moving precise objects on screen. Not because one side of the brain switches on and the other off – it isn’t that simple – but because visual, spatial thinking puts the question in a different form. Often, that is enough to reveal what wasn’t visible before.

4. Sketches are allowed to be wrong

One of the most useful things about an early design sketch is that nobody expects it to be right first time.

Lines move. Equipment disappears. Whole sections get crossed out, and a fresh sheet of tracing paper goes over the top so you can start again. That’s genuinely valuable in the early stages of kitchen planning, because early design isn’t about proving the first idea works but finding out which ideas don’t, as cheaply as possible.

There’s very little cost to abandoning a pencil line. There’s an enormous cost to discovering a kitchen doesn’t work after the equipment has been specified, the services coordinated, and the build already underway. Good design needs cheap ways of being wrong. Sketching is exactly that.

5. One sketch creates the next

Very few good kitchen layouts arrive fully formed. They evolve, sketch by sketch.

Goldschmidt has also written about what she terms serial sketching – design as a sequence of small transformations, where each sketch feeds forward into the next. That’s a close match for what actually happens on the page. Move the cookline, and prep needs rethinking. Adjust prep, and refrigeration needs reconsidering. Move refrigeration, and suddenly the delivery route makes more sense…  except now circulation has a problem, so another line moves.

The solution develops through iteration, not revelation. A clean, resolved CAD layout has often started life as several layers of tracing paper covered in arrows, notes, crossings-out and dead ends. Those messy drawings aren’t what happened before the design work. They’re where a good deal of it actually happened.

6. Sketching keeps a design open to challenge

Technology, specifically CAD in commercial kitchen design, is indispensable. We use it for accurate layouts, equipment coordination, dimensions, services information, and giving the wider project team something solid to build from.

But accuracy carries something else along with it: authority. A perfectly straight CAD line looks intentional, even decided. A fully populated layout can look resolved long before the underlying idea has actually been tested. A pencil sketch says something different. It says: this can still change.

That’s precisely what you want at an early stage. You want chefs to challenge it, clients to question it, architects to draw over it, someone to ask “what happens if we move this here?” The point of the drawing at that stage isn’t to defend itself. It’s to help find the best answer.

7. It makes the process collaborative

Some of our most useful conversations happen standing around a sketch, not a finished layout. A chef can point to the cookline and explain how their team actually works, in practice, not in theory. An operator can flag a service problem before it’s built in. A client can ask why something needs to sit where it does, and we can draw the alternative there and then, in the room.

That changes the relationship between designer and client. Rather than presenting a supposedly finished layout for sign-off, a sketch lets us explore the operation together. Our job was never just to fit equipment into the available square metres. It’s to understand how a catering operation actually needs to function, and translate that into a space that supports it. Sketching gets that conversation happening before decisions become expensive to unpick.

This isn’t only a kitchen thing

Strip away the equipment schedules and the cookline, and the underlying principle isn’t specific to commercial kitchens at all. It’s the same reason some novelists draft by hand before typing, why an interior designer works up a room in loose thumbnails before opening a CAD model, why a painter does studies before the canvas, why a fashion designer works a silhouette on a croquis before it ever reaches a pattern – and why a chef doesn’t arrive at a finished dish in one go either. A new dish gets tasted, adjusted, plated wrong, replated, pushed too far one way and pulled back, long before it’s stable enough to put on a menu. Nobody expects the first version off the pass to be the version that ships. It’s a sketch you eat.

Donald Schön described this kind of thinking as a “conversation with the materials”. The basic idea is that when you make something (a sketch, a model, a draft, a dish) it gives you something to react to. You notice things, change things, and the thing you’re making starts to influence what you do next. Although Schön developed the idea through studying architects and other professionals, the principle applies much more widely. We don’t always think our way to a finished answer and then make it. Quite often, we work out what the answer is by making something first.

What all of these have in common with a kitchen layout is the same trade: a rough, cheap, disposable version of the thing, made before the expensive, precise, hard-to-undo version. A discarded page of prose costs a writer nothing. A wasted test batch costs far less than an unsuccessful menu launch. A discarded floor plan costs a kitchen client rather more, if it isn’t discarded until after the tiling’s gone in. The pencil sketch, the terrible first draft, and the dish that gets sent back to the pass three times are all doing the same job. Giving the idea somewhere safe to be wrong before anyone’s committed to it.

We just happen to do ours on tracing paper, over a kitchen.

So where does technology fit in?

Everywhere. Once it’s doing the right job.

This isn’t an argument against CAD, BIM, 3D visualisation or AI. They’re powerful tools, and their role in commercial kitchen design will only keep growing. But better technology doesn’t make sketching redundant, because sketching and CAD were never doing the same job in the first place.

We sketch to explore. We use technology to resolve.
