First Brick House, Monterey State Historic Park
California State Parks
Monterey, California

Built in 1847, the two-story gable roof building is the oldest surviving brick structure from California’s early American period. California State Parks stabilized and restored the building for interpretation, including replacement of deteriorated original brick.

ARG’s conditions assessment included review of building documentation and field conditions, employing visual examination and material investigation. We performed materials research and testing to identify agents leading to deterioration and potential treatments for masonry conservation. We undertook additional materials research and testing to determine the physical and mechanical properties of original and replacement bricks and mortars to determine the factors affecting the condition of the bricks and to better inform decisions on future repair materials.
