The goal for each project is to simply design beautiful, well-proportioned, and edited places that just feel right. Our response is to look beyond the site to the external influences that can connect a place to its larger environment.  An understanding of scale and context is paramount to delivering a sense of calm and permanence, while an appreciation of tactile experience and execution of details bring satisfaction and delight.

Richard Arentz

Richard carries his design and observation skills forward as lead designer and Principal at Arentz. “My goal is to find the most fitted relationship between our clients and the landscapes that they choose to live in.”

Richard’s agrarian roots formed his connection to the landscape at a very early age. “You understand the seasons, the impacts of weather, and the interconnectedness of man to nature, growing up on a farm”. He was given the freedom to explore, study and sketch the natural and cultivated landscape. His skills of observation were further enhanced by opportunities to work in 14 different countries, working on environmental, cultural, historical, and economic issues of landscape. After graduating from the Pennsylvania State University with a B. S. in Landscape Architecture, his first day of work was in Heidelberg, Germany. This first experience led to other firms and opportunities with incredible mentors. Projects ranged from resort development in Tunisia, to NATO facilities in Iceland, Embassies in Uganda and Peru, to spending a year living and working on a new government center in Tokyo, Japan.

Richard’s work is frequently published and has been recognized with many awards from professional groups and publications. Richard received the 2014 Distinguished Alumni Award from the Pennsylvania State University, College of Arts and Architecture. He has served on design juries and lectured at Penn State and Garden Clubs throughout the metropolitan area and in England.
