Harry Vanderbilt Wurdemann House, Historic residence in Lake Forest Park, United States.

The Harry Vanderbilt Wurdemann House is a two-story, four-bedroom wood-frame house on a concrete foundation, with 4,180 finished square feet. Its rectangular plan loosely follows a Mediterranean villa style, and it has two porticos with eight pillars each. It stands on a knoll overlooking Lake Washington.

Built in 1914, this house was among the earliest structures in Lake Forest Park when the community was first taking shape. Its inclusion in the National Register of Historic Places in 1990 acknowledged its importance to the area's architectural development.

In 1990 the Seattle Symphony leased the mansion for several months, raising funds through entrance fees. In 2014, private tours were offered to benefit the Shoreline Historical Museum & Heritage Center. The house was built for Harry and May Wurdemann after they moved to Washington.

The house is a private residence on a knoll above Lake Washington and is not open to the public. Its entrance has changed from a wide circular drive from the southeast to a small street from the north. Occasional private tours have been offered, as in 2014 for the Shoreline Historical Museum & Heritage Center.

The original property once included a gardener's cottage, poultry house, boiler shed, and greenhouse surrounding the main residence. These outbuildings revealed how wealthy households of that time were organized and how they used their land for daily operations.
