Abstract:A small but growing number of design firms are pursuing research activities that extend beyond project-based work, and even large and established firms are seeking new ways to integrate research more formally, and more meaningfully, into their practice. Now experiencing a moment of particular momentum, the complex relationship between research and professional practice in landscape architecture, and the role of research in professional design offices, has increasingly figured in discussions in academic literature and popular forums. This article contributes to this dialogue and body of knowledge by several means: first, through impassioned, personal statements from the authors about the purpose and importance of research in practice; second, through interviews and surveys with 21 design firms about their approaches, accompanied by practical advice for firms seeking to enhance their research efforts; and finally, through a proposition and practical orientation, extracts theories and design rationales through comprehensive analyses of projects. The discussion suggests that the three pathways are not isolated from one another in actual operation, but overlap across project-based research, methodological innovation, and experience synthesis, and require open and collaborative platform-building to continuously advance disciplinary knowledge production. call to action from the authors addressed to the discipline of landscape architecture. Collectively, these contributions confirm and shed further light on how professional landscape architecture firms are utilizing creative and diverse models for research, from significant resource commitments and dedicated staff to decentralized models and oneoff, opportunistic efforts. Two new primary motivations and two new models for research in practice are described, along with new drivers, mechanisms, approaches, and outcomes. The article concludes with the authors' proposition for what is needed to expand research in practice and strengthen its connections to academia, extending an invitation for further dialogue and community-building around practice-based research.
