Whidden–Kerr House and Garden, Prairie School villa in Multnomah County, United States.

The Whidden-Kerr House is a Prairie School villa in Multnomah County featuring characteristic horizontal lines and expansive windows. The residence sits above the Willamette River with surrounding gardens that connect the building to the natural landscape.

William M. Whidden designed and built this residence in 1901 as an expression of the Prairie School movement. The Kerr family acquired and owned the property from 1911 until 1987.

The estate is also called High Hatch Estate, and the formal garden was further developed by Thomas Kerr Sr. and his wife Mabel Macleay after they bought the property in 1911. The grounds lie in the unincorporated communities of Riverwood and Dunthorpe, south of Portland and north of Lake Oswego.

The house is a private residence and cannot be visited; the property is not open to the public. It stands in the unincorporated communities of Riverwood and Dunthorpe, south of Portland and north of Lake Oswego. The site overlooks the Willamette River.

The property is also known as High Hatch Estate, a name visitors rarely encounter in listings. It straddles the unincorporated communities of Riverwood and Dunthorpe, south of Portland and north of Lake Oswego. The separate carriage house, now a garage, counts as a contributing feature of the 1988 National Register designation.
