Klaudiush
Interactive 3D civic budget map for GZM Metropolitan Area. Jury-recognized prototype built in 48 hours at AEC Hackathon Copenhagen 2026.
About the project
Klaudiush is a 3D visualization platform that brings civic budget proposals onto an interactive city map, allowing residents to explore investment proposals in their spatial context. The platform aggregates all project information in one place and tracks each project's status — from submission through voting to completion. It works as an overlay on the existing civic budget system, increasing transparency without replacing current tools.
Live Demo
AEC Hackathon Copenhagen 2026
The AEC Hackathon is one of the most important international events connecting architecture, engineering, and construction with technology. The Copenhagen edition brought together architects, urban planners, programmers, and smart city specialists from across Europe.
Our team designed and built the Klaudiush prototype in under 48 hours. The concept was recognized by the jury and sparked discussions about civic budgets among hackathon participants and industry experts from companies like Henning Larsen, confirming that the need for digital inclusivity and transparency in participatory processes is universal, and that 3D visualization is a direction that resonates with industry leaders.
Pitch Deck
Problem
Based on the evaluation of Gliwice Civic Budget 2024, four key barriers limit citizen participation:
- Scattered information — project details are hidden in technical documents and PDFs published across many different sites. Residents often don't know where to find data on project status.
- No spatial context — proposals use geodetic reference numbers instead of clear map visualizations. Residents struggle to assess whether an investment affects their neighborhood.
- Poor project monitoring — there is no single, transparent place where residents can track current progress, costs, and responsible entities.
- Low visibility of completed projects — many completed investments remain "anonymous" — residents use infrastructure without knowing it was built through the civic budget.
Solution
Klaudiush directly addresses each of the four problems identified in the GBO evaluation:
- One place for all information — all project data (description, budget, location, status, 3D visualization) collected in a single view. No more searching through multiple websites and PDFs.
- 3D visualization instead of geodetic codes — each project is placed on an interactive 3D city map. Residents immediately see where the investment will be built and how it will change their surroundings.
- Transparent project lifecycle monitoring — the platform tracks every stage: from submission through voting to completion. Residents can check progress, costs, and responsible entities at any time.
- Visibility of completed investments — completed projects remain visible on the map with a "Completed via GBO" label, building trust and inspiring participation in future editions.
Additional value
Comments, discussions, and voting patterns collected on the platform create a qualitative picture of resident preferences across districts. The city gains not just vote counts, but real justification for why certain initiatives are popular — a solid foundation for validating ideas, making better investment decisions, and building trust in the participatory process.
