Designing with Trees: Integrating Architecture and Arboriculture

Trees are among the most valuable assets within the built environment, contributing to biodiversity, climate resilience, visual amenity, and occupant wellbeing. However, within the development process they are often viewed primarily through the lens of planning constraints, root protection areas, and regulatory compliance. This can result in missed opportunities to integrate existing trees into the design process in ways that enhance both architectural quality and long-term environmental outcomes.

Successful development near trees requires a deeper understanding of the relationship between architecture and arboriculture. Decisions relating to site layout, foundations, drainage, levels, building form, and construction methodology can significantly influence both tree health and building performance. When these considerations are addressed early in the design process, it is often possible to achieve outcomes that protect mature trees while maximising development potential and design quality.

This session explores how architects can move beyond compliance-led approaches and adopt more integrated design strategies when working with existing trees. Participants will examine the technical, planning, and design challenges associated with tree retention and development, while gaining practical insight into creating projects where buildings and trees can successfully coexist. Drawing on architectural and arboricultural perspectives, the webinar highlights how thoughtful design can transform trees from perceived constraints into valuable design assets.
