Recent job at Strawbery Banke Museum in Portsmouth, NH. We excavated and restored the Marshall Pottery site stone foundation originally built sometime around 1699. Inside the restored foundation we built a bioretention pond. A granite swale was then built to divert rainwater into the pond. Stonework and swale done by Bobby Cantwell. Surrounding roads were then regraded to wrap up this project!
We always enjoy getting to work at Strawbery Banke Museum. It’s such a unique and beautiful place, with so much history, and the people who make it all happen are truly great to work with. We’re grateful for the opportunity to be part of projects there!
