About Us

OneEarthLogoTreeGrnBrownThe guiding principle at One Earth is to design landscapes that provide long lasting beauty and value. We strive to create unique projects in line with our customers needs. We encourage the use of drought tolerant, water efficient plants and designs that minimize large areas of thirsty flora such as bluegrass. As we are a design-build company, our designer and craftsmen work together through all phases of a project to ensure quality and accuracy.

The owner Jim Zarka has over 35 years of experience and a Bachelor of Science in landscape architecture from Michigan State University (1978). Jim is uniquely qualified to help you design the landscape of your dreams.
