Cherrywood Planning Explorer

A map-first tool for exploring planning applications in the Cherrywood Strategic Development Zone (SDZ) in Dún Laoghaire–Rathdown, south County Dublin. Browse, search, and map every planning application in the area — seeing at a glance what has been applied for, whether it was granted or refused, and where it sits on the ground.

Cherrywood is one of Ireland's largest urban regeneration projects — a new town of around 24,000 homes being built on former agricultural land and golf courses. Thousands of planning applications have been filed over the years, and keeping track of them through the council's own system is... not easy. This fixes that.

Where does the data come from?

All planning data is publicly available information published by Dún Laoghaire–Rathdown County Council via their ArcGIS REST services. The data is fetched live and cached — it reflects the council's records as closely as possible.

This site is not affiliated with or endorsed by the council. For official records, to check the status of a specific application, or to submit observations on a live application, use the DLR Planning Portal.

Who built this?

Built by Dan Stuart, a Cherrywood resident frustrated by how hard it is to track what's being built nearby. A side project that grew into something more polished. Find him on LinkedIn.
