THE PRINCIPAL
DAVID LASHLEY BLA, OALA, CSLA
PRINCIPAL AND SENIOR LANDSCAPE ARCHITECT

“I love life; love my wife and all my seven kids; love being a landscape architect and a hockey goalie. What more could I ask from life.”
“I have a broad range of interests that drives everyone in my family wild because I’m always doing something; helping my kids with school, piano practices, and skating, hockey, skiing at Calabogie and Jay Peak, camping, walking in Europe, Christmas, fly fishing in NY, climbing in the Adirondacks, travelling to Newfoundland and to BC to visit family, off-roading my Land Rover, canoeing in Algonquin, watching live football, the odd beer, good wine, great food keep me busy after hours, and working with a terrific staff at our office studio on a wide range of interesting projects keeps me more than busy”.
Growing up on an Ottawa Valley farm, in a small town coupled with extensive travel and camping in Eastern Canada and the United States, generated Dave’s interest in the different natural and cultural landscapes of North America. Dave believes that understanding the intertwined relationships of people and nature is key to the design of various landscapes that address people’s needs while respecting the need to protect natural systems and create a truly sustainable world environment.
As a high school student he thought he would be an architect because he loved to draw and build things, but his love of being in natural settings continued to lead him to look for something else. One day in his guidance office, flipping through university courses, he noticed the term “landscape architecture”. “I had no idea what the profession was, but it seemed to be the right fit”, says Dave. After a couple of years at university and some “real soul searching”, Dave realized that the profession really did fit him.
Dave notes that he was lucky in his early career to work with Provincial Parks in both Alberta and Prince Edward Island developing a clear understanding of human influence on nature and a sustainable design philosophy. His PEI experience allowed him to broaden his knowledge of design to include architecture, engineering, and landscape architecture while he was the Supervisor of Design for Parks and Tourism. “Entering the world of private practice in an urban environment in Charlottetown and then Ottawa proved to be exciting as the range of projects ensured that I would never have a dull day at the office”, says Dave. In November 1986, the decision to start Lashley + Associates was an exciting period for Dave. Despite a number of recession periods and personal challenges over the past quarter century, Dave has enjoyed building this firm into one of Eastern Ontario’s premier LA practices. “Today, the firm is both experienced and youthful with an exciting future in landscape architecture”, says Dave. “Thank you to my family, friends, staff, colleagues and competitors who have helped shape me, and my practice as a landscape architect”.
