PAIN POINTS

W3 AG's existing website no longer reflected the quality and professionalism of their engineering work. The design felt outdated, the service structure was unclear, and visitors had no intuitive way to understand what the company offered or how to get in touch. The overall experience was leaving potential clients without confidence.

SOLUTIONS

We approached this as a full digital transformation, starting from brand identity and moving through UX strategy, UI design, and development. The new website gives W3 AG a clean, modern presence that clearly communicates their services, builds trust with prospective clients, and guides users naturally toward a consultation.

OVERVIEW

W3 AG is a Swiss engineering firm specializing in sustainable building technology systems, including heating, cooling, ventilation, and sanitary solutions for residential and commercial properties. Despite their strong technical expertise and solid project portfolio, their digital presence did not match the standard of their work. We were brought in to redesign and rebuild the website from the ground up, working with the client's existing brand assets to create a structured, modern, and fully developed web presence from UX design through to cloud deployment.

OUR DECISION

15 days. That sounds short for a complete website project. It was possible because we made one decision early: W3 AG's brand identity is good. It doesn't need reinventing, it needs presenting better. No rebranding process, no scope creep, no lost time. Straight into UX strategy and development. The key architectural decision was the two-tier navigation separating industries from services. It solves the core problem with technical services: for non-engineers they're hard to grasp. Splitting them creates access without sacrificing depth.

UX/UI Design

Every screen across W3 AG's website was designed in Figma following a structured UX process, from user flow mapping and wireframing to high-fidelity UI.

UI Components

Desktop View

The desktop layout feels structured and confident, with a strong hero, logical service flow, and clear calls to action throughout. Clean typography and quality project imagery give the site a professional tone that matches W3 AG's engineering standards.

Main Pages

Industries

The Industries page helps visitors quickly identify whether W3 AG serves their sector, from residential buildings to hotels and healthcare facilities, making it easier to find relevant information fast.

Industries

Services

Each service page was structured with a clear scope, planning methodology, and expected outcomes, technical enough to build credibility while remaining accessible to non-engineering clients.

Services

Work

The Work section presents completed projects with measurable results front and center, turning the portfolio into a genuine credibility-building tool rather than a simple image gallery.

Blog

The Blog supports W3 AG's long-term visibility, covering topics like energy efficiency and building standards to attract organic traffic and position the company as a knowledgeable industry voice.

Every section was built to adapt naturally to smaller screens. Navigation, content layout, and CTAs all respond cleanly to mobile, giving users the same quality experience regardless of device.

We built the site using custom WordPress theme development with hand-written PHP, HTML, and CSS to implement the Figma designs precisely. JavaScript was used selectively to keep the site fast and focused.

Key Development Challenges & Solutions

01Challenge: Complex Service Structure into Clear Navigation

02Challenge: Bilingual Content Management

03Challenge: Building a CMS the Client Could Manage Independently

Problem: Organizing technically detailed services into a simple, intuitive website was a core challenge.

Solution: We created a two-tier navigation separating Industries and Services, giving users a relevant entry point from either angle.

01

Problem: The website needed to serve both German and English-speaking audiences consistently

Solution: We implemented a clean language-switching system in WordPress maintaining the same structure and experience across both languages.

02

Problem: The previous website was hard to update, leaving content outdated over time.

Solution: We structured the WordPress backend with clearly labeled editable blocks, giving the W3 AG team full control over content without any technical dependency.

Conclusion

Many Swiss SMEs sit with the same problem as W3 AG: strong performance, a solid client base, and a website that doesn't show it. The design ages, the structure grows organically and at some point the digital presence no longer communicates what the company truly is.

The solution wasn't a cosmetic refresh, it was a structural realignment: clear user guidance, bilingual infrastructure, a CMS W3 AG manages on its own. Delivered in 15 days. W3 AG shows that digital transformation doesn't need months-long projects or endless rebrands. Sometimes it just needs one clear decision. And someone to execute it.
