Highlighted Projects

Point Reyes Lighthouse

Constructed in 1870, the Point Reyes Lighthouse has shined its light over California’s treacherous coastline for over 150 years. Having remained solid and vigilant for well over a century in a windy, highly exposed marine environment, the Point Reyes Lighthouse was in need of significant restoration.  In order to restore the lighthouse to its original integrity and appearance while creating a safe and weathertight space, our team worked to identify the material and fabrication techniques of the main structural members and identify processes for reproduction.

The restoration project at Point Reyes Lighthouse won the 2022 Preservation Design Award for Restoration.
