Typically, web development is separated from web ‘design’ in that design focuses on the visual impact of a site as well as the usability, and ‘development’ tends to be more the nut and bolts of the technical architecture and coding.
This is an oversimplification, but for the purpose of separating our services so they can be explained, we’ll talk about web development here as what we might call building a website that needs some level of customisation but not quite as in depth as our bespoke software development service.
