Codebase review
We review your site before writing new code.
Extend Existing Builds
Extend existing websites without a full rebuild. WordPress and Shopify feature work, design refresh, performance fixes, integrations and phased migration planning from Ace Web Development.
What we deliver
Incremental delivery
New features added with minimal disruption to live functionality.
Phased migration
Extension can be the first step before a platform migration.
Extending existing websites
We add features, refresh design and improve performance on websites you already run. Work starts with a codebase review on WordPress, Shopify, custom CMS and hybrid stacks.

Why extending existing websites protects investment
Extend existing builds add features, performance fixes and design refresh on the site you already run instead of discarding URLs, editor training and content built over years. Targeted extension often ships faster and costs less than a full replatform when the underlying CMS and architecture are still sound.
Preserving URL structure and canonical hierarchy protects search rankings and generative citations while you add CRM hooks, new service pages or checkout improvements. A codebase review first confirms extension is viable before you commit budget to incremental delivery or phased migration.
Adding capability to an existing site
Extension applies when your content, URLs and editor workflows still have value and the current platform can support the next set of features with targeted engineering rather than a full rebuild.
If code auditing shows a rebuild is more cost-effective than continued patching, we will say so in the report before extension work is scoped.
Part of custom development
Extend existing builds sits under custom development with integrations and extensions, managed web services, AI integration and code auditing. We work on sites we built and sites from other agencies.
Website extension services
We add features, fix performance and refresh design on existing WordPress, Shopify and custom CMS sites. A codebase review precedes production work.
What extend existing builds is
We add capability, fix performance and refresh design on sites you already run on WordPress, Shopify, custom CMS or hybrid stacks.

Extension is an option when a full enterprise website or small business website rebuild is not yet required by budget or timeline.
When extension applies
Extension is appropriate when:
- Content and URLs are valuable and a rebuild would risk SEO and training investment
- The CMS still fits the business but theme, plugins or apps need updating
- You need new features (portal area, booking, calculators, API sync) without migrating data
- Performance or security issues can be fixed on the current platform
- You plan a phased migration: improve the current site first, replatform later
Code auditing may show that rebuild is more viable than continued patching. We include that in the report.
Review before build
Before production code we review:
- Theme or template structure and dependency risk
- Plugin, app and custom code inventory
- Hosting, caching and Core Web Vitals baseline
- Security exposure (outdated PHP, vulnerable plugins, exposed endpoints)
- Integration map (CRM, payments, analytics)
- Editor workflow constraints
Findings define a fixed scope: what to extend, what to replace, what to defer.
Typical extension work
WordPress: custom blocks, ACF fields, new templates, WooCommerce features, plugin replacements, caching and hardening.
Shopify: new sections, collection templates, metafields, cart behaviour, app integrations.
Design: refresh within the existing theme using templated designs or custom tailored design for key templates via web design services.
Integrations: CRM, payments, marketing automation via integrations and extensions.
Performance: asset optimisation, lazy loading, CDN and cache configuration.
AI: chat, search or automation via AI integration on the existing CMS.
Phased migration
Extension is often the first phase of a longer plan: stabilise on the current stack, add landing pages for campaigns, then migrate section by section. Optimisation and CRO and A/B testing may run on live traffic during this period.
After extension
Managed web services can handle patches and monitoring. When extension is no longer sufficient, see websites and landing pages and platforms for net-new build options.
Search and AI visibility
URL stability, redirect maps and template hierarchy affect how search engines and crawlers read your site after changes. We document what changed and which pages remain canonical for service definitions.
Factual copy on updated templates helps generative tools summarise your offers accurately.
