Twitter co-founder Evan Williams hopes to tear down his $3 million home in San Francisco to build a new net zero home with solar panels and a green roof — and his Planning Department application has already exceeded 140 characters.
Before planners even had a chance to review documents for the project, it had amassed a pile of more than 240 opposition letters from neighbors on the quiet, tree-lined Edgewood Avenue in the Parnassus Heights neighborhood. Neighbors became aware of the potential new construction when Williams and his wife, Sara, partnered with architectural firm Lundberg Design to do outreach in the neighborhood, according to the San Francisco Examiner.
The home — listed in city records as a "potential historic resource" — was built in 1911 by architect Louis Christian Mullgardt. However, an environmental evaluation application submitted in May by project sponsors argued that extensive renovation work conducted in the 1970s detracted from the home's historic status.
According to the documents, preliminary plans call for a new zero net energy home with solar panels, a green roof and sun-friendly windows. To address common conflicts over obstructing views, the height of the home is set to be lowered by 18 feet to preserve a line of sight to the San Francisco skyline.
If approved, plans call for the new home to be 7,700 square feet, up from its current 5,000 square feet.
