CMS & framework selection
Choosing WordPress, headless CMS (e.g. content-API driven) or a fully custom stack based on your content workflow and technical requirements.
Website Development
Custom Website Development, Engineered to Perform
We build the website itself — the CMS, the codebase, the integrations — with performance, accessibility and search-friendly markup treated as build requirements, not afterthoughts.
Sites that were designed well but built poorly
We regularly inherit sites with strong design that underperform because of how they were coded — bloated JavaScript, unoptimised images, no caching strategy, and markup that gives search engines nothing to work with.
- Heavy page weight from unoptimised images and unnecessary third-party scripts
- CMS chosen for developer convenience rather than the client's actual content workflow
- No structured data, so search results show plain blue links instead of rich snippets
- Integrations (CRM, payment, booking) bolted on with fragile, unmaintained code
Architecture decisions made against a performance budget
Before we write code, we agree on a CMS or framework fit for your team's workflow, a page-weight and load-time budget, and which integrations need to be reliable on day one. Every technical decision during the build is checked against those constraints.
What's included
Service components
Front-end and content integration
Semantic, accessible markup with performance-optimised images, fonts, copy and video placed to match the approved design and brand voice.
Back-end & integrations
CRM, payment gateway, booking system and third-party API integrations built with error handling and monitoring.
Structured data implementation
Schema markup for organisation, breadcrumbs, articles or products, aligned with technical SEO requirements.
Performance engineering
Caching, image compression, lazy loading and script deferral aimed at Core Web Vitals targets.
Migration & redirects
URL mapping and 301 redirects when moving from an existing site so ranking pages don't lose equity.
Process
How we deliver it
- Step 01
Technical scoping
Defining CMS/framework choice, integrations, hosting and performance budgets before development starts.
- Step 02
Environment & architecture setup
Development, staging and production environments with version control from day one.
- Step 03
Build sprints
Iterative development with regular reviews against the agreed design and performance targets.
- Step 04
QA & performance testing
Cross-browser, cross-device testing plus Core Web Vitals and accessibility checks before launch.
- Step 05
Launch & post-launch monitoring
Deployment with rollback plan, followed by monitoring of real-world performance and error logs.
Outcomes
What you get out of it
Faster load times
Performance budgets baked into build decisions, not chased after launch.
Fewer post-launch bugs
Structured QA against defined browsers, devices and integrations before go-live.
An always-on business channel
A reliable, mobile-ready website makes your services, proof and enquiry paths available whenever prospects are researching.
Maintainable codebase
Documented code and version control so future developers aren't starting from scratch.

FAQ
Frequently asked questions
01Which CMS do you recommend?
It depends on who manages content and how often it changes. WordPress suits frequent editorial updates by non-technical teams; headless setups suit teams needing more control over front-end performance or multiple content channels.
02Can you integrate our existing CRM or ERP?
Yes, we've integrated common CRM, payment and booking systems via their APIs; we'll confirm feasibility during technical scoping for anything more specific.
03Do you migrate content from our old site?
Yes, including URL mapping and redirects so pages that currently rank don't lose their search visibility.
04How do you approach Core Web Vitals?
We set LCP, INP and CLS targets during scoping and make rendering, image and script-loading decisions against those targets throughout the build.
05Will the site be easy for our team to update?
Yes, we choose and configure the CMS around your team's actual editing workflow and provide documentation or training as needed.
