Design & UX
UI Design
The visual layer of your product — typography, colour, spacing, components and states — designed as a system engineers can build from, not a set of pretty pictures nobody can reproduce.
Overview
UI design is the visual layer of a product: how it looks, not how it works. That distinction matters more than it sounds. UX design decides the structure — the flows, the information architecture, the order things happen in; you can read about that under our UX Design service. UI takes that structure and makes it real to look at: the typography that sets the tone and carries the hierarchy, the colour that guides the eye and signals state, the spacing and layout that give a screen rhythm instead of clutter, the icons, and the way every component behaves as it is hovered, focused, filled in, disabled or shown an error. It is the difference between a wireframe that proves the idea and a screen a person actually uses.
Done well, UI is largely invisible. The hierarchy tells you where to look without you noticing why, the buttons look pressable, the errors are legible, and the whole thing feels considered rather than assembled. Done badly, it is a product that looks fine in a single hero screenshot and falls apart the moment you try to build it — inconsistent spacing, a colour palette that fails contrast, six subtly different button styles because nobody wrote down the one that was meant to be used, and states that were never designed at all, so the engineer guesses and the guesses do not match.
The thing that separates a UI that scales from one that decays is a design system: a set of reusable tokens and components — the colours, type scale, spacing steps, radii and elevations named once and used everywhere, and the buttons, inputs, cards and navigation built from them. A design system is not decoration; it is the infrastructure that keeps a product visually consistent as it grows and makes it fast to build, because a screen becomes an arrangement of parts that already exist rather than a fresh painting every time. We design the visual layer as that system from the start, and we design it to be handed to engineers cleanly — because a design that cannot be built accurately is not finished, however good it looks in the file.
Who it’s for — Teams whose product looks inconsistent, dated or thrown-together, who are scaling a UI past what ad-hoc screen-by-screen design can hold, or who need a design system so a growing product stays coherent and fast to build.
What you get
- A visual language defined as tokens — colour, typography scale, spacing steps, corner radii, elevation and iconography — named once and applied consistently, not eyeballed screen by screen
- A component library covering the real building blocks of your product: buttons, inputs, forms, cards, tables, navigation and the rest, each built from the tokens rather than styled in isolation
- Every meaningful state designed, not just the happy one — hover, focus, active, disabled, loading, empty and error — so engineers build from a specification instead of guessing
- Key screens designed to production fidelity, showing the system doing real work rather than an abstract style guide nobody can apply
- Accessibility built into the visuals: contrast that passes WCAG, visible focus states, and meaning never carried by colour alone
- A responsive approach — how the layout, type and spacing behave from a narrow phone to a wide desktop — decided deliberately rather than left to break
- A clean handover engineers can build from: organised files, named tokens, documented components and the states and edge cases spelled out
What UI Design does for you
Credibility you can see before you read a word
People judge a product visually in the first second, before they have used a single feature. A considered interface — clear hierarchy, consistent spacing, typography that is set rather than dropped in — signals competence and earns trust. A cluttered or dated one undermines a good product before anyone gives it a fair try, and that first impression is expensive to overcome.
A design system that pays off across the product’s life
The upfront cost of defining tokens and components is real, but it is an investment, not an expense. Every screen built afterwards is faster because it composes existing parts; every new person is onboarded into a pattern instead of inventing one; and a rebrand becomes changing a set of named values rather than repainting the whole product by hand. The return compounds the longer the product lives.
Fewer arguments, faster shipping
When the button, the spacing scale and the error state are defined once and written down, design and engineering stop relitigating them on every screen. Decisions made once at the system level are decisions not remade a hundred times in review, which is where a surprising amount of a team’s time quietly goes.
Why teams choose us for UI Design
- We design the visual layer as a system from the start — tokens and components — so it stays consistent and fast to build, rather than a stack of one-off screens that drift apart
- Our UI is designed for implementation: component-based, tokenised and handed over cleanly, because we operate what we build and know what engineers actually need to reproduce a design faithfully
- Accessibility is part of the design, not a later audit — contrast, focus states and state-not-by-colour-alone are built in, so a good-looking screen is also a usable one
- We are honest about the line between UI and UX, and about the fact that a beautiful screen which ignores usability is a failure — we will not sell you visuals that photograph well and fall apart in use
What UI Design includes
The concrete pieces of work this covers — scoped to what your problem actually needs.
Visual hierarchy and layout
Deciding what the eye should reach first, second and third, and using size, weight, colour, contrast and spacing to make that happen without the user ever noticing the machinery. A screen with clear hierarchy feels calm and obvious; one without it feels busy even when the content is identical.
Typography and type systems
A type scale — sizes, weights, line heights and spacing — chosen to carry hierarchy and set the product’s tone, then defined as tokens so headings, body and labels stay consistent everywhere. Typography does more of the work of a good interface than almost anything else, and it is where thin design shows first.
Colour and theming
A palette built as tokens — primary, neutral, semantic colours for success, warning and error, and the surfaces and text that sit on them — with contrast checked and, where you need it, light and dark themes derived from the same named values rather than maintained as two separate paint jobs.
Component and interaction states
Every component designed across the states it actually has — default, hover, focus, active, disabled, loading, empty and error — because these are what a mockup omits and an engineer then has to invent. Designing them is the difference between a specification and a suggestion.
Iconography, spacing and motion
A consistent icon style and grid, a spacing scale that gives layouts rhythm instead of arbitrary gaps, and motion used with restraint — transitions that clarify what changed and where something came from, rather than animation for its own sake that slows the interface down.
Design systems and tokens
The whole of the above pulled together into a reusable system: tokens as the single source of truth for the visual language, and a component library composed from them. This is the capability that turns a set of screens into something a team can build on, extend and keep consistent for years.
Where it fits
Building a design system for a scaling product
A product that grew screen by screen and now has five button styles, three spacing conventions and no shared source of truth. We define the tokens and component library, reconcile the drift into one coherent system, and give the team something new features can be built from consistently instead of freshly reinvented.
A visual refresh of a dated interface
A product whose function is solid but whose look has aged and is costing it credibility. We rework the visual layer — typography, colour, spacing, components — over the existing structure, modernising how it looks without gambling on a redesign of how it works.
Turning UX structure into buildable screens
You have flows and wireframes — the UX is settled — and now need the visual layer that makes them real and hands to engineering cleanly. We apply the visual system to the structure, design the states, and produce a handover that engineers can build faithfully rather than approximate.
Bringing consistency across a product suite
Several products or modules that should feel like one family but do not, because each was designed in isolation. We build a shared system — tokens and components with room for per-product variation — so they read as a coherent whole while still allowing each its own character where it needs one.
How we approach UI Design
We start from the structure, not a mood board. UI is the visual layer on top of a UX foundation, so before we choose a typeface or a palette we need to know what the screens have to do and how they are organised — either from your existing UX work or from ours. Designing the surface before the structure is settled is how you end up with beautiful screens that solve the wrong problem, and we would rather get the order right.
From there we build the system before the screens, or at least alongside them. Rather than designing thirty pages and then trying to reverse-engineer a pattern out of them, we define the tokens and the core components early, then compose screens from those parts. That is what keeps the product consistent, makes the design fast to extend, and — because the components map to the components engineers actually build — makes the handover clean. Throughout, accessibility and the full set of states are treated as part of the design, not a pass someone does at the end, because those are exactly the things a good-looking mockup quietly omits.
How we deliver UI design
We begin by making sure the structure underneath is settled, because UI is a layer on top of UX and designing the surface before the flows are decided wastes both. Working from your existing UX artefacts or ours, we confirm what the key screens have to do and how they are organised. Then we establish the visual direction — typography, colour, the overall feel — as a small set of decisions applied to real screens, not an abstract mood board, so you are reacting to your product rather than to inspiration.
Once the direction is agreed, we build the system: tokens for colour, type, spacing, radius and elevation, and the core components composed from them, each designed across all its states. Screens are then assembled from those parts, which is both faster and the thing that keeps everything consistent. We check contrast and accessibility as we go rather than at the end, and we decide responsive behaviour deliberately so the layout does not simply break at the edges.
We finish with a handover built for the people who have to build it: organised files, named tokens that can map to code variables, documented components, and the states and edge cases written down. Because we operate what we build, we know that the gap between a design and its implementation is where quality quietly leaks out — so we close it on purpose rather than hoping it holds.
Design systems and tokens
A design system has two layers, and keeping them separate is what makes it durable. Tokens are the foundation: named values for every visual decision — this colour, this text size, this spacing step, this corner radius, this shadow. Nothing in the interface uses a raw value; everything references a token. That indirection is the whole point. When the token changes, everything built on it changes with it, which is why a rebrand or a theme becomes editing a set of names rather than hunting down every hard-coded colour by hand.
On top of the tokens sits the component library — buttons, inputs, cards, tables, navigation — each composed from tokens rather than styled in isolation. A component is defined once, with all its states, and reused everywhere, so consistency is the default rather than something enforced through vigilance in review. Adding a screen becomes arranging existing components, which is faster and inherently on-pattern. This is the same mental model engineers use when they build a component-based front end, and that is deliberate: when the design system and the code system share a structure, the handover is clean and the built product actually matches the design.
We build the system to fit the product’s real scale — a small product does not need the ceremony a large one does, and over-engineering a design system is as much a mistake as having none. We size it to what you are actually building, and we structure the tokens so they can map directly to the variables in your codebase, so the design system and the front end reference the same source of truth rather than drifting apart the moment both start to change.
Accessible visual design
Accessibility is not a separate concern from UI — it is largely decided by the visual choices themselves, which is why we treat it as part of the design rather than an audit bolted on afterwards. The most common failures are visual ones: text that does not have enough contrast against its background to be read, focus states that were designed away because they looked untidy, and information conveyed only by colour so it disappears for anyone who cannot distinguish it. Each of those is a visual decision, and each is cheap to get right at design time and expensive to retrofit.
We check colour contrast against the WCAG thresholds as we choose the palette, not after — for body text, for interface elements, and for the text that sits on coloured surfaces, which is where contrast quietly fails. We design visible, deliberate focus states for everything interactive, because a keyboard user who cannot see where they are on the screen cannot use the product at all, and a faint or missing focus ring is one of the most common accessibility defects in otherwise-polished interfaces.
And we make sure meaning never rests on colour alone. An error is a colour and an icon and a message; a required field is marked, not merely tinted; a status is labelled, not just shaded. This is the point in the memory’s honesty principle applied to visuals — a beautiful screen that a portion of your users cannot actually use is not a success, and we will say so rather than ship it and let the contrast failures surface in a later audit or a complaint.
Signs it’s time
- Your product looks inconsistent — spacing, colours and button styles vary screen to screen because there was never a single defined pattern to follow
- The interface looks dated or thrown-together next to competitors, and it is costing you credibility even where the underlying product is strong
- You are scaling — more screens, more features, more people building — and designing each page from scratch no longer holds together or keeps up
- You need a design system: a reusable set of tokens and components so the product stays coherent as it grows and engineers stop rebuilding the same button five ways
How UI and UX fit together
It is worth being precise about the split, because the two words get used interchangeably and the work is genuinely different. UX is how a product works: the structure, the flows, the information architecture, the sequence of steps, what happens when. UI is how it looks: the visual layer laid over that structure — the typography, colour, spacing, components and states that turn a wireframe into a screen. You can have good UX and poor UI (a well-organised product that looks amateurish and dated) or good UI and poor UX (a beautiful product that is confusing to actually use). Neither is a success on its own.
This service is the visual layer specifically. It assumes there is a structure to sit on — either UX work you already have, or the UX Design service where we do that structural work first. We are explicit about this ordering because designing the visual surface before the structure is settled is one of the most common and expensive mistakes in product design: you polish screens that solve the wrong problem, then have to redo the polish once the structure moves. Getting the sequence right — structure, then surface — saves that waste.
Where a project needs both, we do both, in order. But we keep the distinction clear in how we talk about the work, because conflating them is how teams end up asking for a UI refresh when the real problem is a UX one, or vice versa. Naming the actual problem is the first step to fixing the right thing, and we would rather tell you which layer needs the work than sell you the layer we were asked about.

Runbooks & SLOs
What changes
A product that looks considered
A coherent visual language — type, colour, spacing and components working together — so the interface reads as deliberate and trustworthy rather than assembled from parts that never met.
Consistency that survives growth
A design system of tokens and components that keeps every new screen on-brand and on-pattern, so the product stays coherent as it scales instead of drifting.
Design engineers can actually build
A tokenised, component-based, fully-stated handover that maps to how the interface gets built — so what ships matches what was designed, without a guessing game.
Industries we serve
Domain knowledge changes what gets built. A few of the sectors we know before the first meeting.
How pricing works
- The single biggest driver is whether you need a design system or a set of screens. Defining tokens and a component library is more work upfront than styling a handful of pages, but it is what makes everything afterwards faster and consistent — so for anything that will grow, the system is the more economical route across the product’s life, not just at the outset.
- The number of distinct components and screens matters more than raw page count. Ten screens built from a shared set of components is far less work than ten genuinely different layouts, because most of the cost is in designing each unique component and all its states, not in arranging parts that already exist.
- Whether the UX structure already exists changes the scope. Applying a visual layer to settled flows and wireframes is a contained piece of work; if the structure is not yet decided, that is UX work which comes first and is scoped separately — we will tell you plainly which of the two you actually need rather than quietly folding one into the other.
- Depth of states, theming and responsiveness adds real effort where it is genuinely required. A product that needs light and dark themes, a full set of interaction states across many components, and carefully-designed responsive behaviour from phone to desktop is more work than one with a single theme and simpler layouts — and we scope to what the product needs rather than gold-plating states nobody will use.
Typical timeline
- 01
Direction and foundations
We confirm the underlying structure, then establish the visual direction — typography, colour and overall feel — as decisions applied to real screens rather than an abstract mood board, so you are steering off your actual product.
- 02
Tokens and core components
We define the tokens and build the core component library from them, each component designed across all its states — the foundation everything else composes from and the part that keeps the product consistent.
- 03
Screens and responsive behaviour
Key screens assembled from the components to production fidelity, with responsive behaviour and accessibility — contrast and focus states — decided deliberately as we go, not left to break at the edges.
- 04
Handover and support
A clean, documented handover engineers can build from — organised files, named tokens mappable to code, documented components and states — with support through implementation so what ships matches what was designed.
Why teams choose us for UI Design
We design for the engineers who have to build it
Because we operate what we build, we know exactly what an engineer needs to reproduce a design faithfully — named tokens, defined components, every state spelled out — and we design to that standard. A file that looks impressive but cannot be built accurately is a failure we have seen too often to repeat.
We treat the design system as infrastructure, not decoration
Tokens and components are the part of UI that determines whether a product stays coherent as it grows or decays into inconsistency. We build that layer deliberately and size it to your product, so the visual language is something the team can build on for years rather than a snapshot that dates the moment the next feature ships.
We build accessibility in, and are honest when it is missing
Contrast, focus states and meaning-not-by-colour are part of how we design, not a later audit. And if a direction we are asked for would fail those, we say so — a beautiful screen a portion of your users cannot use is not something we will ship and call done.

Common questions
What is the difference between UI design and UX design?
UX is how a product works — the structure, the flows, the information architecture, the order things happen in. UI is how it looks — the visual layer laid over that structure: typography, colour, spacing, components and states. This service is the visual layer specifically. It assumes there is a settled structure to sit on, either UX work you already have or our UX Design service, where we do that structural work first. The two are genuinely different disciplines, and we keep the distinction clear because conflating them is how teams end up asking for a UI refresh when the real problem is a UX one, or the reverse.
Do we need a design system, or just some screens designed?
It depends on scale. If you have a small, stable product with a handful of screens, a full design system can be more ceremony than it is worth, and we will tell you so. But if the product is going to grow — more screens, more features, more people building — then designing each page in isolation stops holding together quickly, and a system of reusable tokens and components is what keeps it consistent and fast to build. The upfront cost is real, but for anything that will live and grow it pays back across the product’s life. We size the system to what you are actually building rather than over-engineering it.
Why do the interaction states matter so much?
Because they are exactly what a good-looking mockup leaves out, and what an engineer then has to invent. A button is not one design; it is default, hover, focus, active, disabled and often loading. An input has empty, filled, focused, disabled and error states. If those are not designed, the engineer guesses, and the guesses will not match your intent or each other. Designing every state is the difference between handing over a specification and handing over a suggestion — and it is a large part of why a built product ends up looking less polished than the design it came from.
Can a design be beautiful and still be a failure?
Yes, and it is a common one. A screen that photographs well for a single hero shot but ignores usability and accessibility is a failure however good it looks: text that fails contrast and cannot be read, focus states designed away because they looked untidy, meaning carried by colour alone so it disappears for some users, or a layout that breaks the moment there is real content in it. We treat accessibility and the full set of states as part of the design, not a later pass, precisely so that a good-looking screen is also a usable one. We would rather tell you a direction fails those tests than ship it and let the problems surface in an audit.
How do you hand the design over so engineers build it accurately?
We design for implementation from the start, which makes the handover clean rather than a translation exercise. The visual language is defined as named tokens that can map directly to the variables in your codebase; the components are built the way engineers build components, each with its states documented; and the edge cases — empty, error, long content, small screens — are spelled out rather than left to interpretation. Because we operate what we build, we know the gap between a design file and the shipped product is where quality quietly leaks out, so we close it deliberately: organised files, documented components, and support through implementation so what ships matches what was designed.
