Precedent analysis is the systematic analysis of plans that enables comparison between plan types as well as within a plan type. The goal is generic design knowledge that can be of use in day-to-day practice and theory development. The core issue in this paper is how the successful approach of precedent analysis in architecture developed by Guney, can be reworked to make it also applicable for landscape architecture. One of the first issues to be addressed, is how the dynamics of landscape architectural form and design can be integrated into the approach of precedent analysis. Design in landscape architecture being process oriented and at different levels of intervention, was the basis for an analytical framework. This analytical framework relates perception, analysis and intervention. One of the conclusions is that precedent analysis can form the bases for theory development as a body of coherent, generic and explicit design knowledge.
