Wix and Squarespace are capable platforms. For a sole trader or a new practice with three projects to show, they may be entirely sufficient. The question is whether they'll still be sufficient in two years.

The limitation isn't design. Both platforms have improved significantly and can produce clean, professional-looking results. The limitation is structure. When a practice grows to fifteen, thirty, fifty projects, the absence of a proper CMS becomes a real problem. There is no way to build a filtering system that lets a visitor find schemes by programme type, scale or planning authority. Project pages are built one by one, manually, with no shared field logic. Adding a new team member or updating a service description means editing multiple pages individually. The site becomes harder to maintain precisely as the practice grows and needs it most.

Squarespace in particular is difficult to migrate away from. The content is locked into proprietary templates in a way that makes moving to a more flexible platform time-consuming and occasionally expensive. Practices that build on Squarespace early often find themselves rebuilding from scratch when they outgrow it, rather than evolving what they have.

Webflow sits in a different position. It offers the design flexibility of a custom build with a CMS that non-technical team members can manage independently. For practices with genuine portfolio depth and a need to filter, segment and present work with precision, it is the platform that grows with you rather than constraining you.
