Ping comes from a Chinese Character: 平.

It is short for Ping Chang (平常), which means common, ordinary and humble. It also means a state of calmness, a sense of balance and peace of mind. It is an idealism we want our design to achieve.

Ping is a landscape architecture and design firm founded in St. Paul, Minnesota, with the purpose of bringing design excellence to a broader audience. We believe design excellence is not defined by high-end materials or expensive finishes. It can emerge from ordinary things, a thoughtful arrangement of space, a deep understanding of place, or a simple gesture that enriches daily life.

We approach every project with humility rather than a preconceived style. We believe good design is about discovering what is appropriate to a site. It grows from the land, its history, and the lives of the people who inhabit it. Through careful observation and thoughtful intervention, we craft experiences and stories that deepen people's connection to the landscape.
