Custom Website Development & WordPress Design | SdV

Website creation & custom development

Custom website development, designed, built and maintained by one team.

Custom website development or bespoke WordPress sites: our team scopes, designs and builds your project, then stays responsible for its search visibility (SEO) and its evolution after launch, on infrastructure we run ourselves, in France.

No obligation. A first conversation to scope your needs, before any commercial proposal.

Icône design UX/UI pour la création de site internet

UX before UI: we understand your users and your goals before we draw anything. That’s what saves you from starting over six months after launch.

  • User journeys, personas, site structure
  • Visual mock-ups approved with you before development
Icône développement de site WordPress

A custom theme built around your brand and your content, not a generic theme barely adapted and soon outdated.

  • Theme development and integration
  • Carefully chosen plugins, kept up to date, with no pile-up of unmaintained plugins that weaken the site
Icône développement web sur mesure

Business applications, client portals, extranets, or integration with your existing tools, when your needs go beyond what a CMS can handle.

  • Bespoke development
  • Integration with your systems (CRM, ERP, APIs)

A well-built website that nobody finds won’t convert. We structure the site architecture, content and markup for search from the design stage, so there’s no catching up once the site is live.

  • Technical SEO audit and optimisation
  • Content and tag structure for organic search
  • Ranking tracking
Icône refonte et migration de site internet

Dated usability, an ageing design, pages getting slower to load: we redesign your site without losing your history or your search rankings.

  • Audit of your current site
  • Content and redirect migration plan
Icône maintenance de site internet

Maintenance is part of our commitment, not just delivery: we stay responsible for your site long after launch.

  • Corrective: bugs, broken forms, display issues
  • Adaptive: updates to WordPress core, theme and plugins
  • Evolutive: new features on request
  • Security: we keep track of security updates

A good website depends as much on the quality of its design as on the strength of what keeps it running afterwards.
Here’s what, in practice, makes that happen with us.

The same team designs, builds, hosts and evolves your site, with no loss of context and no responsibilities split across several providers.

Design is your brand’s first impression: we build it to inspire trust and turn a visit into an enquiry, not just to look attractive.

Site structure, markup, performance: these decisions are made when the site is designed, so it’s ready to rank from launch, with no corrective audit needed six months later.

Four steps, from scoping to maintenance, with the same point of contact throughout.

Step 01

Scoping & mock-ups

Analysis of your needs, functional scope, UX/UI mock-ups approved with you before any development.

Step 02

Development

Development of the site or application, on WordPress or fully custom depending on the scope agreed at the scoping stage, with regular progress updates rather than a black box until delivery.

Step 03

Acceptance testing & go-live

You approve every page before it goes live, which then happens on our infrastructure.

Step 04

Ongoing maintenance

Security updates, fixes and improvements on request: we stay responsible for the site after launch.

Your questions about website design and custom development

Both, depending on your needs: WordPress for brochure sites, corporate sites or standard web applications; custom development when your needs go beyond what a CMS can handle, such as a business application, a portal or an integration with your existing tools.

Yes. The same team that designs the site also plans its structure, markup and performance for search. It isn’t an add-on bolted on at the end.

You’re free to do so: the code belongs to you and remains reusable if you want to take it back in-house or switch provider.

Yes. We stay responsible for your site after launch: security updates, fixes and improvements on request.

We start by understanding your users and your goals (that’s UX) before moving on to visual mock-ups (UI). This is the stage that builds visitors’ trust from the first few seconds, and saves you from starting over six months after launch.

It depends on how complex the project is: a brochure site is quicker to build than a business application with integrations. We give you an estimated timeline at the initial scoping stage, before you commit to anything.
