The Creative Leaders in Design and Construction

As the leaders in rockwork, water features and themed environments, Outside the Lines brings a team of knowledgeable and reputable designers, estimators and project managers to your project, no matter what its size and scope.

The World’s Finest Rockwork, Water Features and Themed Construction

OTL is headed by J. Wickham Zimmerman, a seasoned entrepreneur and industry leader. When Zimmerman founded OTL with Hugh F. Hughes, they focused on providing the world’s finest rockwork, themed construction and specialty water feature projects.

After its formation, OTL immediately established itself as the touchstone for the industry, and the company’s excellent reputation grew quickly throughout the architectural community.

We Make Projects Geo-Believable®

OTL is committed to providing and preserving the world’s finest habitats, waterscapes, landscapes, and natural environments.

We studied, learned and even coined the phrase “geo-believability®,” the art of making rockwork and water

features as geologically realistic as possible. If you’re seeking a realistic, natural setting, every stream we build will flow and bend the way nature intended, and every artificial stone we create will look indigenous to the area.

Or Out of This World

If you’re seeking an environment that’s more other-worldly, our rock, water and themed features make the mundane disappear and bring out the magic and wonder of your project.

The team at OTL has created some of the most imaginative and mind-bending themed environments in the industry. We’ve created water features that dance to the music of Frank Sinatra and re-created the snow-capped mountains of the Swiss Alps.

As skilled artisans, our work is restricted only by your imagination.
