PlaceChangers — Planning software built around real project delivery
PlaceChangers provides practical software and support for planning, urban design and development teams to run clearer community consultations online, use place-based evidence to understand local need, and move projects forward with confidence. We combine built environment expertise, spatial and built environment software design, and hands-on delivery support to help teams de-risk projects and deliver better outcomes across the built environment.
Agile delivery for complex planning strategies and masterplans
We work in partnership with planning consultants, architects, developers and multidisciplinary teams to deliver visual, interactive engagement and practical insight into local community needs, creating a better experience for all involved while saving time on project setup and reporting.
Based in Newcastle upon Tyne, PlaceChangers has supported 120+ projects across the UK, Ireland and New Zealand.
Founder-led delivery with specialist support where it matters
PlaceChangers operates with a focused core team and a trusted network of specialist collaborators. Clients get a clear point of accountability, while projects still benefit from the right blend of planning, technical and engagement expertise.
This approach keeps delivery close to the work. It also gives us the flexibility to bring in added capability where a brief calls for it, whether that is digital engagement, place analysis, mapping or communications support around consultation and regeneration.
