This proposal is based on the landscape architecture practice Dermot Foley Landscape Architects. The first phase of the research will investigate practice using an adaptation of Friedrich von Schiller’s On Naïve and Sentimental Poetry, in order to better understand two types of practitioners, the naïve and the sentimental. The research will then focus on practice work using ‘live’ projects to demonstrate findings as they emerge. It is not intended to use von Schiller’s theory to impose a framework on the practice. Rather, the theory is proposed to be used as a lens through which to understand the practice and the research will focus on the design process within the practice as the PhD progresses.
