Design systems and brand in code

The tokens, components, and rules that make everything you ship look like it came from the same place, delivered as working code.

  • Scoped per project
  • UK based
  • Founder-led delivery

A design system is the set of decisions you only want to make once. Colour, type scale, spacing, corner radius, motion, how a button behaves when it is loading, what an empty state looks like. Made once and encoded, they stop being reopened on every screen.

We deliver design systems as code, not as a slide deck. A PDF of brand guidelines does not stop the fourth shade of grey from appearing in your product. Tokens and components in the codebase do, because the wrong choice stops being the convenient one.

This is usually the least glamorous line on a proposal and the one that pays for itself fastest. It is the difference between the tenth screen taking a day and taking a week.

Included

What you get

Every engagement includes all of this. None of it turns up later as an extra.

01

Design tokens

Colour, type, spacing, radius, elevation, and motion defined once as variables and consumed everywhere. Change the token, change the product.

02

A component library

The real components you ship: buttons, inputs, selects, modals, tables, empty states, and loading states, built with their edge cases handled rather than their happy path.

03

Accessibility as a default

Focus states, keyboard navigation, contrast ratios, and semantics built into the components, so accessibility is inherited by every screen instead of audited after the fact.

04

Dark, light, and reduced motion

Themes and motion preferences handled at the token layer, which is the only place they are cheap to handle.

05

Documentation people will read

Short, practical guidance on when to use what, written for the developer who joins in eight months.

06

Adoption, not just delivery

We migrate real screens onto the system as part of the work. A design system nobody has adopted is a folder, not a system.

In detail

How we approach it

Why systems fail

Most design systems die the same way. They are built in isolation, launched with an announcement, and then not used, because using them is more work than not using them. The team keeps shipping the old way and the system rots into a museum.

The fix is not enthusiasm, it is ergonomics. If the system component is the fastest way to build the screen, adoption happens without a mandate. We build for that, and we migrate real screens as part of the engagement so the system launches with proof that it works.

Tokens are the whole trick

Almost everything valuable about a design system comes from having one source of truth for the primitive values. Dark mode, a rebrand, a density change, an accessibility fix for contrast: each of those is a small change at the token layer and an unbounded amount of work without it.

We define tokens in layers: primitives, then semantic roles, then component-level values. It sounds like over-engineering on a small product and it is the reason a redesign eighteen months later takes days rather than a quarter.

How this fits alongside a build

For new products, the system is built as part of the product rather than before it. Extracting patterns from three real screens produces a better system than designing one in the abstract.

For existing products, we typically start with an audit: every colour, type size, and spacing value currently in use. That list is usually longer than anyone expects and it makes the case on its own.

Process

How it runs

Four steps from first call to launch. No surprises, no disappearing acts.

01

Call

One focused call to understand what you need, who it is for, and what success looks like. You leave with a clear, written scope and a proposal.

02

Prototype

You are clicking through a working prototype with most of the core features live, early in the project. Real screens in the browser, not static mockups.

03

Refine

We shape the prototype into the finished product, folding in every amendment you ask for. Nothing ships until you have confirmed the final build.

04

Deploy

We take it live on the hosting provider and domain of your choosing, fully wired up, and stay close after launch to keep it running smoothly.

FAQ

Design Systems questions

What exactly do I get?

Design tokens, a component library in your codebase, documentation, and real screens migrated onto the system. It is working code in your repository, not a design file or a PDF of guidelines.

Do I need a design system for a small product?

If you have fewer than about ten screens and one person building them, probably not yet. The value appears when more than one person is shipping interface, or when you expect to. We would rather tell you to wait than sell you something that will sit unused.

Can you work with our existing brand?

Yes. That is the common case. We take existing brand guidelines and turn them into tokens and components, which is usually the first time the brand has actually reached the product rather than the marketing site.

Do you use Tailwind, or something else?

We generally use Tailwind with CSS variables as the token layer, because it is fast, widely understood, and easy for another team to pick up. If your codebase uses something else we will work in that rather than force a migration.

Does this include accessibility compliance?

The components are built with focus management, keyboard navigation, semantics, and contrast handled by default, which gets you most of the way to WCAG 2.2 AA. Full compliance also depends on your content and your specific flows, so we scope a proper audit separately if you need to certify it.
