Moin Europa!
Europa-Union Hamburg combines several digital offerings under one organizational umbrella together with Info-Point Europa and the Young European Federalists. GSWE developed a shared multi-site and multi-domain platform that technically connects different websites without forcing them to lose their own editorial focus, domain, and identity. The value for the client lay in a solution that combines shared technical foundations, an intelligent design system, UI/UX design, and lower maintenance effort with the necessary independence of the individual presences.
Challenge
Europa-Union Hamburg needed to bring several organizationally related but independently presented websites into one shared technical solution. With europa-union-hamburg.de, infopoint-europa.de and jef-hamburg.de, there were multiple offerings with their own target groups, domains and editorial direction. For the client, it was crucial that this would not become a rigid unified website, but a structure in which independence, shared technology and consistent design could work together.
Requirements for the shared platform
What was needed was a solution that enables central maintenance and cross-domain usability without sacrificing the identity of the individual presences. Especially in a non-profit context, it was important that additional effort and technical complexity would not grow disproportionately with every further website.
- multiple websites with their own identity in one shared application
- need for central maintenance and shared design logic
- economically viable structure for future extensions
The three sites illustrate the difference between shared infrastructure and shared editorial responsibility. Bringing websites onto one technical platform must not automatically force identical content or a single public identity. The challenge was therefore to enable reuse where it reduces maintenance while retaining differences that matter to each audience. This distinction also provides a useful starting point for associations that operate several independently positioned public services.
Solution
GSWE implemented a multi-domain and multi-site platform based on Symfony and Sulu. What mattered was not just technical consolidation, but a structure in which shared components, central content management and individual delivery work together in a meaningful way. This allowed multiple websites to run on a common foundation without losing their editorial independence and visual character.
How GSWE built the platform
The solution was designed so that content can be maintained centrally and reused across domains when needed. At the same time, a shared design system was created that generates synergy while still leaving enough room for different appearances. In this way, several isolated solutions became one sustainable shared platform that connects editorial work and technology more effectively. That made everyday maintenance and future growth easier to control.
- multi-domain and multi-site architecture with Symfony and Sulu
- central content management with targeted delivery
- shared design system while preserving independence
Symfony and Sulu provided the shared technical foundation, while the design system connected reusable presentation with distinct websites. Maintaining content centrally and selecting where it appears are different responsibilities: not every item automatically belongs on every domain. That separation explains how the platform supports shared work without collapsing the Europa-Union, Info-Point Europa and Young European Federalists into one undifferentiated website.
Result
With the new platform, Europa-Union Hamburg now has a sustainable technical foundation for its digital information and participation offerings. Multiple websites can be operated more efficiently, maintained more consistently and further developed on a shared basis without losing their independence. This created not only a technical solution, but a structure that noticeably reduces organizational and economic effort for the client.
Result from the client's perspective
GSWE created a shared platform that combines central maintenance, consistent design and targeted publishing. The lasting value appears in better manageability, less friction and a reliable basis for new digital offerings. This is exactly what makes further development across several presences much more predictable. It also supports a clearer editorial and organizational setup for the future.
- more efficient operation of multiple websites
- clearer editorial processes and consistent publishing
- sustainable basis for future extensions
The reference demonstrates a concrete architectural principle: independent domains and audiences do not rule out a shared software foundation. The project outcome is a working combination of these requirements, not a promise that other organisations will achieve identical savings. A comparable platform should be scoped by examining existing websites, content suitable for reuse and the visual differences that need to remain, before deciding the implementation and introduction plan.
Benefit
For Europa-Union Hamburg, the value came from combining efficiency and flexibility. Content can be maintained more efficiently, reused across multiple websites and published in a targeted way without causing the individual presences to lose their own role. At the same time, maintenance effort and duplicated technical structures are reduced, which creates noticeable operational relief for an organization running several public offerings.
Practical value for the client
GSWE created a solution in which synergies across multiple websites become usable and editorial work can be organized more easily. In everyday operation, the effect becomes visible through less friction, more consistency and a stronger basis for future digital expansion. That makes the platform not only more efficient, but also more sustainable over time. It also improves editorial coordination across connected presences.
- lower maintenance effort across multiple websites
- valuable synergies in content, design and operations
The benefit can therefore be understood across two areas of work. Technical foundations do not have to be maintained separately for each website, while editorial decisions can still reflect the purpose of the individual service. This balance matters in comparable projects. A shared platform makes sense when components, content or operational responsibilities can genuinely be reused; belonging to the same organisation is not, by itself, a sufficient reason to consolidate websites.
