Kasboekje van Nederland
Uncovering the financial history of The Netherlands.

A growing database of Dutch financial history.
In collaboration with Dutch TV channel NTR, Utrecht University, and De Ruimte Ontwerpers we created the website for the series Kasboekje van Nederland. Kasboekje van Nederland is a multi-faceted project that explores how the Dutch organized their finances throughout time.

We were brought in to create an online platform where people could get in contact with researchers and send their documents for review. Additionally, this website grew out to become the platform for all the uncovered research, a database of articles, and go-to source for (re)watching or reading more behind the scenes information about the episodes that aired on Dutch national television.

Visualizing financial research
with engaging illustrations.

We worked alongside illustrator Welmoet de Graaf to bring the digital experience to life. Each page features beautifully detailed imagery which tells the story of that episode or section.

The homepage is completely responsive, working across all devices and screens to ensure a high quality viewing experience for all.


The illustrative style is colorful and simplistic which translates well throughout the rest of the website through bold use of block colors. The illustrations draw you to key pages and information about each of the episodes.

The homepage

The entire project
on one page.

The homepage is built around the idea of a hallway. All its sections lead to different pages that contain more information on that part of the research. The user experience is revolved around an older target audience. Our choice of type and high contrast colors are both to improve their experience of the website.

  • Visualizing the past through engaging illustration
  • Homepage is a gateway to other parts of the website
  • Encourages active engagement to submit documents
  • Research articles and shared experiences
Visual components

From illustrations,
to user interface.

The entire website is built with a component system, that is organized by color and structure. The episodes each have an individual combination of colors that set them apart. The thumbnail cards make for easy navigation and are built with user interface components which are customizable to fit any of the episode's colors.

Style elements.

We based our creation of style elements on the bright illustrative style, giving us room to be playful with colour and loose elements.

All of Kasboekje's research and aired episodes are still available online. If you speak Dutch, we highly advise you to watch them and read the research. It's a fascinating topic and we are very excited to have worked on this project. The end result is a diverse and colorful project, much like the dedicated team of researchers, tv-makers, illustrators, and designers that were involved.
