Landscape Architecture, Ecological Restoration, and Planning

Learn About Our Landscape Architecture Company

Based in Blue Bell, PA, SED Design has been providing top-notch landscape planning and design services for more than 18 years. We were one of the first firms to take an ecological approach towards landscaping.

The study and evaluation of environmental conditions, cultural influences, historical impacts, and user needs are the stepping stones of our design strategy. We use research and analysis to reveal the inherent and unique qualities of sites so they may be utilized and enhanced. This approach establishes a scientific basis for the restoration of natural systems and is also a vital design component.

We believe that landscape design should integrate creative and scientific processes to produce exceptional work. This approach contributes to environmental health by restoring life and sustaining the balance of our planet's fragile ecosystems.

SED Design brings innovative solutions to each project. Our firm's public landscapes and private gardens integrate design with low-impact and green principles to meet the programmatic needs of each client.

Our Mission

SED Design is dedicated to the creation of distinctive and evocative spaces in the context of the expansive landscape.
