Laura Hansplant RLA, ASLA, LEED AP
Laura integrates social spaces, rainwater systems and plant communities to create meaningful places where each element mutually supports the whole site. Born in Canada, Laura studied at the University of Toronto and the Pennsylvania State University, where she received a Master’s in Landscape Architecture with a minor in ecology. She volunteers on the US Green Building Council’s Sustainable Sites Technical Advisory Board, where she participates in discussions advancing sustainable design. Through speaking engagements Laura has found a passion for inspiring professionals and students on innovative design. Outside the office, she spends her afternoons exploring the natural patterns of meadows and woodlands, searching for inspiration for her designs. In her test garden, Laura grows native plants, taking note of their character and durability to inform resilient landscape designs. When she can get away, Laura enjoys wilderness canoeing, camping, and hiking with her family.

Civil Designer
Corey Hospes
Corey has four years of experience in land development and site design, covering a variety of project scales form small sites to highways. He discovered a love for the city of Philadelphia after moving here in 2020. Corey found himself both inspired and limited by the grid design of one of the oldest cities in America. The constraints of William Penn’s city layout offer an interesting challenge for site design. To address these challenges, he has developed a passion for green stormwater infrastructure and green space design to manage the aging stormwater system. These spaces can be used effectively not only to manage water, but as urban traffic calming measures to increase pedestrian safety and aesthetically improve the neighborhood. When he’s not in the office Corey enjoys bouldering, board games, video games, and movies.
