Goodbye, paper maze! We developed the Gebouwenpas, a single digital platform that brings together all real estate data
The Flemish government (public sector) faced fragmented real estate data spread across multiple agencies, making it difficult for citizens and stakeholders to access certificates, permits, and reports. ACA Group developed the Gebouwenpas, a scalable digital platform built on Liferay DXP with Spring Boot and Angular, centralising all building data into a single digital passport. Using an agile Scrum and Kanban approach, the solution delivers clear insights, secure access, and a future-proof system for both residential and non-residential properties.
