Custom WordPress theme development, hand-coded for speed

Stop fighting page-builder overhead. I build lightweight, on-brand WordPress themes from scratch using clean PHP, custom Gutenberg block patterns, and ACF custom fields — so your site loads in under 2 seconds, passes WCAG 2.1 AA accessibility requirements, meets Core Web Vitals thresholds (LCP under 2.5s, INP under 200ms, CLS under 0.1), and gives your team genuine editing control without a developer on call.

In short

Custom WordPress theme development means building a bespoke theme in code rather than buying a multipurpose theme or assembling one in Elementor or Divi. The result is a lighter, faster site containing only the code your design needs — no unused CSS libraries, no builder overhead, no plugin conflicts. I build in modern WordPress full-site editing (FSE) with Gutenberg block patterns, or classic PHP themes with ACF custom fields, depending on your team's editing preferences. Most custom themes are delivered in two to four weeks on a fixed price.

Who it's for

Brands outgrowing a multipurpose or generic stock theme Businesses moving off Elementor, Divi or WPBakery for performance Companies with a Figma or Adobe XD design ready to build Sites failing Core Web Vitals because of builder overhead Teams who need clean editor access without developer dependency

What's included

Custom FSE block theme or classic PHP theme — your choice
Pixel-accurate build from Figma, Adobe XD, or Sketch files
Reusable custom Gutenberg block patterns for your content types
ACF custom fields for structured, brand-safe editing
Responsive mobile-first layouts across all breakpoints
WCAG 2.1 AA accessibility compliance built in from the start
Clean, documented, version-controlled code on GitHub or Bitbucket
Editor training walkthrough and handover documentation

How the process works

1

Design & scope

We agree on templates, block components and content types, then I turn your Figma or XD design into a coded component library before any WordPress work begins. No scope surprises.

2

Theme build

I hand-code the theme on a staging site, building reusable block patterns and ACF field groups so your team can edit every section without touching code.

3

Review & refine

You review on staging with real content while I refine spacing, responsiveness and browser compatibility across Chrome, Firefox, Safari and Edge — including iOS and Android mobile.

4

Launch & train

Careful go-live with full backup, plus a documented handover and a short walkthrough so your team can use the block editor and ACF fields confidently from day one.

Common questions

Both, depending on what your site needs. For performance-critical sites, WooCommerce stores, or complex custom designs, I write clean custom code — no builder overhead means faster load times, better Core Web Vitals and easier long-term maintenance. Where a builder fits your team's editing workflow and budget, I build cleanly in Elementor or the native block editor. The right choice depends on your LCP and CLS targets, your team's technical comfort, and whether the design is template-friendly or genuinely bespoke — I'll give you an honest recommendation before quoting.

Yes. I build using custom Gutenberg block patterns and ACF custom fields so your team can update text, images, repeating content sections and entire page layouts from the WordPress block editor — no code knowledge needed. Every build includes handover documentation covering which blocks do what and a walkthrough session on Loom or video call. If your team needs to make more structural changes in future, I can add that capability via targeted block patterns rather than handing the whole site to a page builder.

Yes. I build pixel-accurate themes directly from Figma, Adobe XD, Sketch, or Photoshop (PSD) design files — matching typography, spacing, hover states, and responsive breakpoints to the designer's intent, not an approximation. Before build starts I review the design files for any ambiguity (missing mobile states, undefined interactions) and flag them with questions so there are no mid-build surprises. If you have a design ready and want it converted to WordPress, see also my design-to-WordPress conversion service for straightforward static-to-WordPress builds.

Premium themes like Astra, GeneratePress, or Kadence are well-coded and perform better than page-builder bundles — but they still carry CSS for features your site doesn't use, and their Customizer-based settings become limiting for genuinely bespoke designs. A hand-coded custom theme ships only the CSS and PHP your design needs: that's typically 20–40 KB of CSS vs 150–300 KB for a multipurpose theme plus its companion plugin. The performance difference shows in Core Web Vitals — particularly LCP and CLS. Custom themes also have no update conflict risk, since you own every line of code. The trade-off is cost and timeline: custom themes take 2–4 weeks vs a day to configure a premium theme. For straightforward sites where a premium theme fits cleanly, I'll say so and use one.

Yes, and this is where custom themes have a compounding advantage. Because all CSS is written specifically for your design, there's no unused code waiting to become a liability as content grows. I also configure caching, image optimisation and CDN as part of the launch checklist, so baseline performance is locked in from go-live. Your team adding content via the block editor won't degrade load times the way installing additional page-builder widgets does.
