The Problem
Your Theme Fights Your Design Every Time You Change a Page
Bought themes promise every layout at once. The trouble shows when your brand needs something the demo didn't have, and each fix adds more CSS, another plugin, or a hack the next update erases.
01 · CSS patches
Brand tweaks pile up as custom CSS over the theme.
Brand styles live in theme.json, so blocks inherit them without override CSS.
02 · Unused bloat
Every page loads builder and slider code it doesn't use.
The theme loads only the styles and scripts each block on the page needs.
03 · Lost edits
A theme update erased changes made in the theme files.
Your theme is your own code in Git, so no vendor update overwrites it.
04 · Fragile pages
Editors avoid pages where one click breaks the layout.
Locked patterns keep the structure fixed while your team edits text and images.
You bought a multipurpose theme because the demo looked close enough. Two years later, your header is held together with custom CSS. The theme bundles a page builder and a slider plugin you don't use, and every page loads all of it. A theme update last spring wiped out changes someone made straight in the theme files. Your editors avoid certain pages because one wrong click breaks the layout. And you still pay a yearly license for code that works against your design.
We start with your design and your content, not a demo. With custom WordPress theme development, your colors, fonts, and spacing are set once in theme.json. Each content type gets its own template, and editors fill in patterns without touching the layout. Pages load only the CSS and scripts their blocks use. Your brand shapes the code, not the other way round.
Design tokens in theme.json
Colors, fonts, and spacing defined once, so every block and pattern stays on brand.
Templates for each content type
Pages, posts, services, and archives each get a template built for their content.
Layouts editors can't break
Locked patterns let your team change text and images while the structure holds.
Our Custom WordPress Theme Development Process
From Design Review to Live Theme in Five Clear Steps
You see the theme plan, a styled pattern library, and every template on staging before your live site switches over.
We look at your current theme, plugins, page types, and the design you want. You get an honest call on whether a child theme or a new theme fits, a template list, and a fixed quote.
What's Included
What You Get With WordPress Custom Theme Development
Every theme covers the plan, design tokens, templates, patterns, testing, and launch, sized to how many page types your site has and how much content needs converting.

What Our Clients Say
What Clients Say After Launch
Feedback from teams we have built brand websites and custom themes for.
We had a pretty specific idea of what we wanted our website to become, but I wasn’t sure how easily we could explain all of it to a development team. There were quite a few moving parts, and we were working toward a deadline, so I expected a few things to get lost along the way. That never really happened. They understood what we were trying to achieve, kept us updated throughout the process, and got everything ready within the agreed timeline. The final site feels much easier to navigate, works beautifully on mobile, and is noticeably smoother for our customers. It was a huge relief seeing the original idea actually turn into the website we had in mind.
The mobile experience is probably my favourite part of the new site. We had spent a lot of time making sure the desktop version looked right, and the team kept pushing us to think about how everything would actually feel on a phone too. They were right. The navigation is clean, the interactions feel natural, and everything we’ve tested so far works exactly as it should. They also went through the links, forms, integrations, and other details more than once before launch, which I really appreciated. And even after going live, we could still reach out when something came up. The whole process felt friendly, organised, and surprisingly straightforward.
What I appreciate most is that the website is actually easy for us to manage now. We can update content ourselves instead of sending a developer a message every time we need to change something small. They also paid attention to the technical SEO side, which mattered to us because we didn’t want a new website to create problems for the traffic we already had. I’ve probably asked more questions than I should have since launch, but every question has been handled patiently and without any fuss. The team is easy to work with, they explain things clearly, and when we need something changed, they focus on getting it done rather than making the process complicated.

Work Culture
Why Site Owners Hire Us for WordPress Theme Dev Work
A theme sits under every page you publish. These habits keep yours fast, on brand, and easy for the next developer to pick up.
Child theme first, when it fits
If your current theme only needs a few changes, a child theme may be enough, and we'll tell you before we quote. A rebuild only makes sense when the theme itself is the problem.
Every change in version control
Your theme lives in Git from the first commit, and changes are reviewed before they reach staging. You can see who changed what, and roll back when needed.
Page weight measured
We compare page weight and load time against your old theme on the same pages. You see the difference in numbers, not in a promise.
Accessible from the first template
Templates use proper headings, landmarks, focus styles, and contrast aimed at WCAG 2.1 AA. That work costs far less in the theme than patched in later.
Standards a new developer knows
As a custom WordPress theme developer, we follow the WordPress coding standards and core block conventions. Any WordPress developer you hire later can read the code without a manual.
Your theme, your accounts
The code, the repository, and every asset we create belong to you at handover. There's no yearly theme license and no dependency on us to keep it running.

Good fit
Businesses on a bought multipurpose theme
Your site runs on a marketplace theme loaded with features you don't use, and every brand change means more override CSS.
Teams with a finished design to build
You have an approved Figma design and need a custom WordPress theme developer to turn it into templates your editors can use.
Sites where editors keep breaking pages
Your editors avoid certain pages because one wrong click shifts the layout, and you want patterns that hold their structure.
Owners of a heavily edited old theme
Your theme was edited directly years ago, so updates are switched off, and you need a clean rebuild before the next security issue.
Agencies needing theme help
Your agency sold a custom design and needs WP theme development handled by a team that ships tested code under your name.
Not a fit
No design decided yet
You don't have a design yet and want help deciding how the site should look. Our WordPress Website Design Services page starts with content structure and design first.
Drag-and-drop editing
Your team wants to drag and drop every section freely. Our Elementor Expert for WordPress Sites page covers builder-based sites, which suit that way of working better.
A Shopify store theme
You need a theme for a Shopify store, not a WordPress site. Our Custom Shopify Theme Development page covers Liquid themes and Online Store 2.0 sections.
Budget under $950
Your budget is under $950 for the whole theme. A well-chosen block theme from the WordPress.org directory, with a few style changes, is a better fit for now.

A custom theme from DeveloperLook starts at $950 for a starter block theme with up to 5 templates. A full custom block theme with 12 templates and locked patterns starts at $2,700, and a live-site theme rebuild starts at $5,900. You get a fixed quote after the free theme review.
A starter theme takes 2 to 3 weeks, and a full theme or rebuild takes 4 to 10 weeks. Most of that time depends on how many templates you need and how much old content has to move from shortcodes or a page builder into blocks. Design changes during the build add time, so we settle them early on staging.
Hire a WordPress developer who reviews your theme before quoting and asks whether changes belong in a child theme or a new theme. Ask how they'll keep edits safe from theme updates, whether the code goes into Git, and who owns it afterward. Our free theme review answers those questions in writing, and small customizations get their own quote.
Customize your current theme when the changes are small and the theme is still maintained. Choose a custom WordPress design built as its own theme when overrides keep piling up, pages load slowly, or updates are switched off. A child theme keeps small changes update-safe, and we'll recommend one when it's enough.
We build a custom WordPress theme in five stages: review, plan, build, test, and launch. The plan maps your design to theme.json settings and a template list. The build adds templates, header and footer parts, and patterns in Git. Then we test on staging, run Theme Check, and switch themes on your live site in a planned window.
To create a WordPress block theme from scratch, start with a style.css file holding the theme header and a templates/index.html file. Add a theme.json file for colors, fonts, and spacing, then more templates, template parts, and patterns as the site grows. The free Create Block Theme plugin can export a theme from the Site Editor as a starting point.
You need a local WordPress install, a code editor, and working knowledge of HTML, CSS, PHP, and the block editor. For WP theme development at a professional level, add Git, the WordPress coding standards, and testing on real devices. Making a theme is approachable. Making one that stays fast, accessible, and easy to edit is where experience shows.
Most new custom WordPress themes should be block themes, because the Site Editor, theme.json, and patterns are where WordPress core is heading. A classic theme still makes sense when a key plugin depends on PHP templates or your team works in a classic workflow. We check your plugins during the review and recommend one before any code is written.
No, a theme covers how your site looks and how content is laid out, not features like booking, custom data, or integrations. That WordPress custom development belongs in a plugin, so it keeps working if you change themes later. Our WordPress Plugin Development Services page covers it, and we scope both together when you need them.
You own all of it: the theme code, the Git repository, and every design asset we create. There's no yearly theme license to renew. Your plan includes 30 to 90 days of post-launch support for fixes, and any WordPress developer can maintain the theme afterward because it follows core conventions.
