Designing Environments That Connect People and Nature

Landscape architecture, as defined by, is the intricate study and practice of crafting environments, both outdoor and indoor, across various scales. Originating from the visionary minds of Frederick Law Olmstead and Calvert Vaux, who designed New York City’s iconic Central Park in the late 1800s, this discipline embodies the intersection of design and science, profoundly enhancing natural environments, integrating art, environment, architecture, engineering, and sociology.

Our Approach

At Siegfried, we merge the art and science to craft enduring and impactful outdoor spaces. Our designs seamlessly blend softscape and hardscape elements, responding to natural features, while prioritizing user experience and client vision. Our projects, no longer confined to traditional patterns, now serve diverse functions while embracing sustainability.

As a multi-disciplinary firm, our landscape team possesses the engineering expertise necessary for project success. Leveraging our knowledge and experience, we employ a variety of materials and techniques to deliver optimal solutions. Our team is dedicated to crafting designs that connect people with nature, build community, and instill a deep appreciation for the outdoors across the diverse types of designed spaces within landscape architecture.

What are the Types of Landscape Architecture?

 From urban design to sustainable infrastructure, landscape architecture encompasses diverse types, each playing a crucial role in creating functional and sustainable environments. Now, let’s dive deeper into each type and explore a few of our projects in these areas.

What inspired you to pursue landscape architecture?
I took an Intro to Landscape Architecture class in college and my professor explained landscape architecture as a surgeon to the land, which intrigued me. We carve our ideas into the landscape.

One of the core values of landscape architecture is creating usable spaces for people and being mindful of the existing conditions in which they thrive. As designers, we make sure all aspects of a space work together, from culture, demographics, weather, location, plants, and animals.
