Our Approach

Our Team

Led by Hans Hesselein, Apiary Studio is a landscape architecture firm based in Philadelphia, PA, established in 2015. We provide the full suite of landscape architectural services from site inventory & analysis, schematic design, visualization and rendering, construction documentation and administration as well as master planning and horticultural consulting. We believe in the principles of value-based design that improves the physical environment and contributes to the greater culture around us. We also have an ongoing research project in the form of a small urban nursery in Philadelphia that grows underutilized native and urban-adaptive plant material. We are specialists in successive planting design and thoughtful small-scale design-build landscape projects.
