Chair | Katja Stille  Tibbalds Planning and Urban Design

As an experienced urban designer with a sound basis in architecture, planning and engineering I work collaboratively across professional boundaries to deliver high quality places. My objective is to push the placemaking agenda and ensure we are building people-friendly places. Professionally, I work across a broad spectrum from policy formulation to delivery, including strategic masterplanning, the creation of new communities, regeneration projects and design advice.

Through the UDG, I seek to work with others to unlock the issues that prevent us from delivering good urban design, influence government policy and improve day-to-day practice.
