M. Lloyd Frank Estate, Tudor-style estate in Southwest Portland, United States

The M. Lloyd Frank Estate, also called the Frank Manor House, is a Tudor-style building on the campus of Lewis & Clark College in Portland, Oregon, completed in 1926 by the McHolland Brothers. Its roof is laid with Pennsylvania slate, and a metal gate designed by Oscar Bach stands near the conservatory. The house now serves as the college's administrative center.

The property was built between 1924 and 1926 by McHolland Brothers for M. Lloyd Frank, a co-owner of Meier and Frank Department Store. The landscaped grounds were completed in 1929, finishing the entire residential complex.

The house is built in the Tudor style, completed in 1926, and now serves as the administrative center of Lewis & Clark College. Its metalwork, including a gate near the conservatory, was made by Oscar Bach, while Herman Brookman designed most of the estate.

The Manor House serves as Lewis & Clark College's administrative center on the campus in southwest Portland, so visits are best timed around college business hours. The estate sits on a hill above the Willamette Valley; paths between the house, the Oscar Bach gate and the former conservatory site involve slopes and stairs.

Oscar Bach, a renowned metalwork artist of that era, created the ornamental gates and metalwork throughout the property. This collaboration between architect and artisan reflects the high-quality craftsmanship valued during the early 1900s.
