Turku.fi renewed – A digital leap built on trust and courage

Turku is Finland’s sixth-largest municipality and one of the country’s most significant urban areas. The city’s main communication channel, turku.fi, serves around 200,000 residents and other stakeholders by providing easy access to city services, up-to-date information, and opportunities for civic participation. The website plays a vital role in the city’s daily life – making Turku’s operations more transparent, efficient, and resident-oriented.

Wunder has been the City of Turku’s trusted digital partner for over a decade, working together on numerous initiatives – from earlier website redesigns to continuous development, maintenance, and the “Digikannustin” project.

This story focuses on the most recent complete renewal of turku.fi, one of the most significant joint projects to date. The goal was to create a user-centric, accessible, and future-proof municipal website that offers a first-class experience for both residents and city employees. The renewal was also a technical necessity: the Drupal 7 platform had reached the end of its lifecycle, requiring a modern foundation for the city’s digital presence.

“The starting point for the renewal was to design and implement a new kind of website for the City of Turku – one aligned with the city’s strategy, new management model, and digital and data strategy. The key principle was to ensure customer and user orientation.” 
— Mira Koivumäki-Lindholm, Project Manager, City of Turku

The new site had to serve diverse user groups and a large community of content creators. Equally important was a unified, easily scalable brand identity that could be applied across all city services. To support this, the project also included the design and implementation of the Turku Design System. 

A beta version was released in fall 2024, and user feedback was utilized in the finalization phase before the official launch. This ensured the end result truly met the needs of both residents and content creators.

Key objectives included:

• Designing for diverse user groups
• Creating and implementing the Turku Design System
• Integrating systems to streamline data flow and efficiency
• Ensuring accessibility and usability at WCAG 2.1 AA level
• Building an information architecture that supports intuitive navigation and discoverability
• Strengthening the city’s visual and content identity

The scope and complexity of Turku’s digital ecosystem required a project model that combined the best of waterfall and agile methods.

This hybrid model proved to be the perfect choice – allowing adjustments and reprioritizations along the way without compromising schedule or quality.

“During the project, the focus was redirected or refined several times. Without mutual flexibility and open communication, the project could not have been completed on time and with such excellent results.”
— Mira Koivumäki-Lindholm

Wunder’s extensive experience in developing large-scale municipal digital services was evident throughout the project. The team combined proven solutions with tailored development exactly where they brought the most value.

The renewal was completed on time and within budget, meeting – and in many aspects exceeding – the set goals. This success was made possible by Turku’s courage and trust, combined with Wunder’s diverse expertise.

For many Wundereres, the project was personally meaningful: a large part of the team comes from Turku, which showed in their exceptional commitment and pride in the work.

“Thanks to Wunder’s diverse professionals, we’ve also gained fresh perspectives on current trends like AI utilization. Wunder has outstanding expertise in service design, user-centeredness, and usability – topics we’ve actively explored together.”
— Mira Koivumäki-Lindholm
