Web Design

Custom web design for businesses that know their website needs to do more than just look good. Design that conveys your brand and inspires your visitors to take action.

Web Design Agency

Good web design doesn't happen in a vacuum. It stems from your content, your goals, and the expectations of your target audience. We design websites where form and function go hand in hand, rather than working against each other.

Design follows
the content

Web design built for your content

In the design process, we develop a unique layout for each page type and content format. The form follows the content—not the other way around. Your visitors come to the website with a specific question, a need, or a decision to make. Good web design meets them exactly where they are and guides them to the next step. The end result is a design that works toward your goals, rather than merely serving as decoration.

Relaunch or Redesign?

Not every website needs a complete overhaul. Sometimes a visual update is enough; other times, the entire structure needs to be reimagined. We’ll take a look at your current site and give you an honest assessment: What still works, what doesn’t, and where is the greatest potential for improvement? Based on this, you can decide whether a redesign is sufficient or if a relaunch makes more sense.

Good web design is evident in many details that must work together. Here are the areas we focus on in our design work. Each of these plays a role in determining whether a website actually works or merely exists.

Visual Concept and Brand Identity

Your corporate identity is the starting point for every design decision. We translate colors, typography, and visual language into a digital design that makes your brand recognizable and sets it apart from the competition.

Responsive Design

Every page is designed for all screen sizes—not just scaled down. We develop distinct layouts for mobile, tablet, and desktop, each providing the best viewing experience for that device. Not just a single version that’s scaled down.

Layout and Page Structure

Before we design a single pixel, we define the structure: What pages do you need, how are they connected, and where do your visitors start? A clear information architecture ensures that visitors find what they're looking for.

From Concept to Layout

Before we begin the visual design, we develop wireframes and prototypes. This allows you to test the website’s user experience early on, before colors and images are added. Changes at this stage cost a fraction of the price.

Design Grid

For more complex projects, we build a design system: a library of components, colors, typography, and guidelines. This library ensures that your website remains consistent even as it expands.

Accessible Design

The BFSG has been in effect since June 2025. Accessibility doesn't start with development—it starts with design: contrasts, font sizes, color coding, and user interfaces that work for everyone.

These companies know how we work

Good design doesn’t start with aesthetics, but with the question: What do your visitors need? We analyze target audiences, usage scenarios, and typical entry points before we begin designing. This results in layouts that guide visitors rather than overwhelming them. Every page has a goal: to inform, persuade, or convert. We develop navigation patterns, page hierarchies, and visual anchors so that visitors can intuitively find the next step. In doing so, we take into account the different ways visitors arrive at your website: via Google, social media, or a direct link. The result is a website that feels right, even if you can’t quite explain why. Good user guidance goes unnoticed; bad user guidance doesn’t. As a web design agency, we therefore start by mapping out the paths through the site.

Briefing and Analysis

We start with a conversation: What are your goals, who is your target audience, and what works—and what doesn’t—on your current website? We analyze the current state of your website, take a look at the competition, and work with you to define what the new website needs to achieve. This results in a clear brief that serves as the foundation for everything that follows.

Concept and Wireframes

Before we start designing, we define the structure: site architecture, navigation concept, and wireframes for the most important page types. You’ll see early on how the website is structured and how visitors navigate through the content. During this phase, we also determine which page types you need and how the content will be prioritized. Changes can be implemented quickly and cost-effectively at this stage.

Design and Prototype

Based on the approved wireframes, we develop the visual concept: colors, typography, visual language, and components. Interactive prototypes in Figma show you how the website will feel on different devices before a single line of code is written. We work iteratively and regularly review progress with you. Requests for changes are incorporated immediately until the design is finalized and approved by you.

Implementation and Launch

Once the design is approved, our development team takes over the technical implementation. At our company, design and development work together as part of the same team, which means streamlined processes and no loss of information. Before the site goes live, we test it on real devices and check loading times and responsive behavior. Then the website goes live, and we support the launch. We remain available even after that, whether for adjustments or new sections of the site.
