Green Gables-Fleischhacker, Mortimer, Country House

Why it's listed
Green Gables is a 75-acre country estate in central Woodside, planned as a rustic summer residence. The main house, completed in 1911 to designs by Greene and Greene, has curved-edged gabled roofs of wood shingles laid to imitate thatch, gunite walls and brick trim. Terraced gardens descend southeast from the house to a lily pond and then to a long Roman pool framed by arcades of rough stone. Other features include a swimming pool with bathhouses, a stone dairy house, a barn remnant, a Wurster-designed house, and an older Victorian farmstead. Nineteen built resources are counted, thirteen of them contributing. The estate is significant for its architecture and landscape, largely designed over several decades by Charles Sumner Greene for Mortimer Fleishhacker and his wife, and for the owners' roles in banking, industry and San Francisco philanthropy. It has remained in the family across three generations, with land, use and ownership intact.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
