Designed in 1892 by the architect who designed the Capitol, Edward Clark. The building served as a home for himself, Champ Clark (Speaker of the House from 1911-1919, during Teddy Roosevelt’s Presidency), a brother known only as "the artist", and a sister.
Originally spanning three row houses, the residence was connected through the basement and main floor and contained separate sleeping quarters for each brother upstairs. It has been suggested that Clark incorporated left over tiles and wood from the Capitol into his new home.
On February 14, 1980, H.H. Leonards purchased 2020 O Street, the first row house in the series of connected brownstones. Leonards renovated the townhouse as a bed-and-breakfast and private club. After renovations were completed, Leonards designed and built a new brownstone on the adjacent vacant lot at 2022 O Street. Leonards subsequently acquired three adjacent row houses, each incorporated into the single property. 
In 1998, Leonards opened the O Street Museum inside The Mansion on O Street . The museum includes art, sculpture, music, memorabilia and written manuscripts in the collection. The museum hosts concerts, book signing talks, film screenings  and tours throughout the year.
Today, the property consists of more than 100 rooms of varying architectural, artistic and design periods with hand-painted ceilings, original Tiffany stained glass windows , a two-story Log Cabin , and an Art Deco penthouse.  The unique decor and architecture of the building has been chronicled in books including Four Blind Mice by James Patterson , Afterburn by Zane  and in the young adult series Gilda Joyce: The Dead Drop by Jennifer Allison 
O Street Museum hosts educational programs for all age groups to learn about and participate in the creative process. Programs include artist-in-residence programs,  jammin’  (live music collaboration), songwriters’ workshops, book signings, film screenings  and live performances.
