who we are


Rick Stockton

Prior to co‐founding GreenSpace, Rick worked in the engineering, fabrication and construction industry for the past 40 years.

We are a real estate co-development and intellectual property licensing company providing cost reducing self-storage solutions with an emphasis on envirnomental conservatism. Our technologies have been patent-pending since 2015, now domestically and internationally for multi-story, self-storage facility designs.


Our designs use shipping containers resulting in construction cost savings of $20 - $30 per gross square foot in multi-story self-storage facilities and shortening construction schedules to about 6 months.


We have myriad domestic and international patent-pending inventions filed, protecting not only our initial designs, but also the multitude of ancillary, valuable, and potentially critical discoveries we have made during the conceptual, development, and practical implementation of our designs.
