Squarespace Development in Derry
Custom work on Squarespace for Derry organisations, where anything beyond the built-in options is code injected into a template you do not control. That works well and it means the platform can change the markup underneath your customisations — so the more you add, the more there is to check whenever something is updated.
Why this comes up
The problem
Custom styling targets elements the template generates, an update changed them, and half the customisation stopped applying.
What you get
What we deliver
- Customisation kept to what the built-in options genuinely cannot achieve
- Injected code written defensively, so a markup change degrades rather than breaks
- Everything customised documented, since it is invisible in the editor
- Third-party embeds assessed for their effect on performance
- Commerce configuration completed properly where the site sells
- A record kept of what was changed and why, for whoever inherits it

Squarespace Development in Derry — common questions
- Why is injected code fragile?
- Because it targets markup the platform produces and can change. Styling that depends on a particular class name or structure works until an update alters it, and there is no warning — the site simply looks wrong one morning for no reason anyone can see.
- How much customisation is sensible?
- As little as achieves the requirement. The platform's built-in options survive updates and custom code does not, so anything achievable natively should be, and the customisation budget spent on the few things that genuinely need it.
- Why document it?
- Because custom code is invisible from the editor. Someone maintaining the site later sees a design that does not match the template settings and no indication why, so a short record of what was injected and what it does saves considerable puzzling.
- Is it suitable for a business site?
- For content-led sites with a strong visual requirement, frequently yes. The constraint is that you are working within someone else's system, so the honest test is whether your requirements fit the platform rather than requiring it to become something else.
- Do you work with businesses across County Londonderry?
- Yes. We are based in Leicester, United Kingdom and work with clients throughout Northern Ireland, including Derry and the surrounding County Londonderry area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
- What kind of Derry businesses do you usually work with?
- Cross-border trading systems for businesses working into Donegal, and manufacturing tooling for the north west. Beyond that we work across Manufacturing, Healthcare, Higher Education, Digital and Tourism.
- Do you cover the areas around Derry?
- Yes — we work throughout Northern Ireland, including Belfast, Lisburn. Derry is an urban area of roughly 85,000+, and we take on work across the wider County Londonderry region rather than the city boundary alone.
