Overview

What you get.

Tailored to your goals
SEO-first architecture
Conversion optimized

A custom website starts with a business outcome — more qualified leads, more bookings, more sales — and works backwards. We map user journeys, define the information architecture, and design every page around a clear conversion path.

Everything is built component-first in TypeScript, server-rendered for speed and SEO, and deployed to a global edge network. You own the code, the content and the roadmap.

Off-the-shelf templates are fine for a hobby project, but they carry the same layout, the same plugin overhead and the same limits as thousands of other sites. A custom build lets us shape structure, copy hierarchy and performance around the way your customers actually decide.

We also treat the website as a living product. Analytics, content workflows and component architecture are planned so the site keeps improving after launch instead of needing a rebuild every two years.

Why it matters

The problem we solve.

Your site is your first impression

Most buyers research online before they ever contact you. A slow, generic or confusing site quietly ends the conversation before it starts.

Templates cap your growth

Page builders and themes make custom features, integrations and performance tuning expensive or impossible as your needs grow.

Search visibility is architectural

Rankings depend on crawlable structure, fast rendering and clean markup — decisions made at build time, not bolted on later.

Ownership lowers long-term cost

Clean, documented code you own means no vendor lock-in and any competent developer can extend it.

Scope of work

What’s included.

Discovery & strategy

Stakeholder workshops, competitor audit, KPI definition and a scoped roadmap.

Information architecture

Sitemap, user flows and wireframes validated before any pixel is designed.

Bespoke UI design

A brand-led design system with responsive layouts, tokens and interaction states.

Headless CMS integration

Editor-friendly content modelling so your team publishes without a developer.

Technical SEO

Semantic HTML, schema.org markup, sitemaps, canonical tags and metadata.

Analytics & CRO setup

GA4, event tracking, heatmaps and A/B-test-ready page structure.

Ideal clients

Who this is for.

Service businesses

Agencies, clinics, consultancies and professional firms that win clients through trust and clear positioning.

Growing startups

Teams that have outgrown a no-code site and need a credible, scalable marketing presence.

Established brands

Companies relaunching to fix performance, rebrand or consolidate several old sites into one.

Product companies

Teams needing marketing pages, docs and a blog that share one design system with their app.

Transparent milestones, weekly demos and one point of contact from kickoff to launch.

Goals, audience personas, success metrics and technical constraints are agreed in writing.
02
Wireframes & IA
Low-fidelity layouts and user flows tested for clarity and friction.
03
UI design
High-fidelity mockups in Figma with a reusable design system and responsive breakpoints.
04
Development
Component-driven build with SSR/SSG, CI pipelines and preview deployments for every pull request.
05
QA & hardening
Cross-browser/device testing, WCAG accessibility checks and Lighthouse audits.
06
Launch & handover
DNS cut-over, 301 redirect map, monitoring, training and documentation.

Quality bar

Standards we hold.

Semantic, accessible HTML

Landmarks, headings, labels and focus states built to WCAG 2.2 AA so everyone can use the site.

Mobile-first responsive

Designed and tested from small screens up across a real device matrix, not just resized in a browser.

Performance budgets

Page weight and Core Web Vitals targets set at the start and checked on every deployment.

Security by default

HTTPS, security headers, input validation and secrets kept out of the codebase.

Tooling

Technology stack.

Glossary

Terms we use.

SSR / SSG: Server-side rendering / static site generation — pages are built on the server or at build time so they load instantly and are fully crawlable.
Information architecture: How content is structured and labelled so users find things quickly.
Conversion rate (CRO): The share of visitors who complete a goal action; CRO is the practice of raising it.
Design tokens: Named values for colour, spacing and type that keep design and code in sync.
Schema markup: Structured data that helps search engines show rich results.
CI/CD: Automated testing and deployment on every code change.
Above the fold: The part of a page visible without scrolling — it should state what you do and the next step.
Responsive design: Layouts that adapt fluidly to any screen size.

FAQ

Common questions.

How long does a custom website take?

Most marketing sites ship in 4–8 weeks; larger platforms with custom features take 10–16 weeks. You get a dated milestone plan after discovery.

Will I be able to edit content myself?

Yes. We model your content in a CMS so your team can edit pages, blog posts and media without touching code.

Do I own the code?

Yes — full source ownership and repository access are handed over at launch.

What do you need from us to start?

A short brief, brand assets if you have them, examples of sites you like, and a decision-maker available for weekly feedback. We guide you through the rest.

How do revisions work?

Each design and build milestone includes structured review rounds. Feedback is collected in one place and resolved before moving to the next stage.

Can you write the copy and handle SEO content?

We can shape page structure and messaging with you, and set up the technical SEO foundations. Long-form content writing can be added as a separate scope.
