課題
The existing pre-built WordPress theme created limitations:
- Customization Constraints — Pre-built theme restricted design modifications and feature additions
- Performance Overhead — Bloated theme code with unused features impacted page load times
- Maintenance Difficulty — Theme updates risked breaking customizations, creating ongoing maintenance burden
- Code Quality — Pre-built theme's codebase made it difficult to extend or debug
- Content Migration — All existing content and media assets needed to be preserved during the transition
私たちのソリューション
We rebuilt the entire website using a custom WordPress theme developed from scratch with semantic HTML, modern CSS, JavaScript, and PHP — replicating the original design while optimizing the backend for clean, efficient, and scalable code.
Architecture
- CMS: WordPress with custom theme following template hierarchy and coding standards
- Frontend: Semantic HTML5, modern CSS, and JavaScript for interactive components
- Backend: PHP with WordPress template hierarchy (header, footer, page templates, custom post types)
- Content Management: Full WordPress admin panel compatibility for seamless content updates
Key Features
- Custom Theme from Scratch — Fully custom WordPress theme built with HTML, CSS, JavaScript, and PHP
- Design Replication — Original user experience faithfully maintained while improving code quality
- Content Migration — All content and media assets exported from existing installation and preserved
- WordPress Template Hierarchy — Proper use of WordPress template standards for maintainability

よくある質問
MicrocosmWorks recommends WordPress theme redevelopment when the client has significant existing content, trained staff, and plugin integrations that would be costly to migrate. A custom theme built on modern block editor (Gutenberg) APIs and optimized PHP delivers Core Web Vitals performance comparable to headless setups while preserving the client's existing editorial workflow.
MicrocosmWorks follows a performance-first development approach that includes critical CSS inlining, lazy-loaded images with WebP/AVIF format delivery, minimal JavaScript with deferred loading, and server-side caching through object cache and page cache layers. The result is typically LCP under 1.5 seconds and CLS under 0.05 on mobile devices.
Yes, MicrocosmWorks audits all existing plugins during the discovery phase and designs the theme to maintain compatibility with essential plugins like WooCommerce, Yoast SEO, ACF, and Gravity Forms. The theme uses WordPress hooks and filters correctly so plugin functionality continues working without requiring plugin modifications or replacements.
MicrocosmWorks typically delivers a complete WordPress theme redevelopment in 6-10 weeks depending on the number of unique page templates and custom block types required. The process includes a 1-week discovery phase, 2-3 weeks of design in Figma, 3-5 weeks of development, and 1 week of QA and content migration support.
MicrocosmWorks develops custom WordPress themes at rates of $15-$35/hr, with a full theme redevelopment including custom Gutenberg blocks, WooCommerce integration, and performance optimization typically requiring 200-400 development hours. This is significantly more cost-effective than agencies charging $15,000-$50,000 for comparable scope.
