The amount of work needed to build even a basic website theme in WordPress is quite large, but as most sites require similar things they all start in much the same way.
This website is built by our partnership business Seja Design and utilises their framework. A ready-built WordPress theme is often not suitable as they can be very generic and may not customise well; this is where using the framework helps.
For all intents and purposes, the site is custom built, but the scaffolding needed to build the site is already in place, we just add in the graphical elements.
