New Mansion Plans Submitted for 3456 Washington Street in Presidio Heights
Preliminary development plans have emerged for a significant residential project at 3456 Washington Street in San Francisco’s affluent Presidio Heights neighborhood. The initiative, overseen by a trust associated with Doris F. Fisher, co-founder of Gap Inc. and a prominent local philanthropist, seeks to replace the existing structure with an expansive three-story mansion.
Project Overview
The proposal outlines a modern estate measuring approximately 11,125 square feet, which marks a 30% increase in size from the current residence built in the late 1950s, with a subsequent expansion in the 1990s. The new design includes:
- Main Residence: 10,450 square feet across three levels.
- Accessory Dwelling Unit (ADU): 678 square feet featuring two bedrooms, designed for versatility or guests.

Architectural Features
The Obata Noblin Office has been appointed as the project architect. Key highlights of the project include:
- Ground level dedicated to a three-car garage, fitness center, hot tub, sauna, and an indoor pool.
- The second floor will host two dining areas, a media room, and a terrace offering scenic views.
- The top floor will feature five bedrooms, along with multiple bathrooms for convenience.

Ownership and Development Process
The property is held under the ‘DDF Article 3 Trust’, with Doris F. Fisher acting as the trustee. Fisher’s influence in San Francisco is notable, as she co-founded Gap Inc. with her late husband Donald in 1969; the company has maintained its headquarters in the city.
The current plan involves demolishing the existing home with a focus on compliance with local regulations. The application utilizes Senate Bill 330, which stabilizes planning codes to expedite the development process. Notably, a recent Historic Resource Evaluation designated the existing structure as ineligible for individual listing under any California Register criteria, easing the demolition process.

Next Steps
The development application is in its preliminary phase and is not yet a formal request for a construction permit. Gibson Dunn & Crutcher LLP is identified as the project applicant, and financial details regarding the construction budget and timeline are still to be confirmed.
Conclusion
This ambitious project on Washington Street reflects the ongoing development dynamics in one of San Francisco’s most prestigious neighborhoods. As plans progress, further updates will be anticipated concerning construction timelines and community impact.
