The top five elements in the outdoor design category are illustrated above.
Consumers prefer sustainable—yet tech-friendly—design elements for their outdoor living spaces, according to the 2017 Residential Landscape Architecture Trends Survey conducted by the American Society of Landscape Architects (ASLA). For the first time, wireless/internet connectivity entered the top 10 project types, suggesting that people want a backyard that allows them to enjoy both nature and connectivity.
Landscape architects were asked to rate the expected popularity of a variety of residential outdoor design elements in 2017. The survey was fielded in February and netted 817 responses.
The top landscape and garden elements include native plants (82 percent), low-maintenance landscapes (79 percent) and food/vegetable gardens (77 percent). Pergolas
(50 percent), decks (41 percent), fencing (40 percent) and arbors (39 percent) are expected to be the most popular outdoor structures.
