Herrero renovated five 3- to 4-story residential buildings and three 2-story World War I vintage hospital wards into commercial office space for the TIDES Thoreau Center for Sustainability on San Francisco’s historic Presidio grounds. The project was completed in two phases of construction and included seismic upgrades for all eight historical buildings involved.

Herrero completed the interior work, utility infrastructure around the buildings and landscaping within 6 months due to funding constraints. Sustainable, recycled, and environmentally acceptable materials we reused throughout. Fire sprinkler and alarm upgrades were included in the overall MEPF upgrades.

Work was completed with the continuous supervision of historical architects, ensuring that all historic elements were aligned with the Presidio’s preservation standards. Additionally, the special nature of the project is that its occupants were a group of non-profit and environmentally sensitive organizations, whose are deeply invested in sustainability and the health of our planet. Consequently, the design reused of as many existing materials as practically possible, as well as many recycled materials and non-polluting energy efficient materials throughout.
