The McLachlen Building is a historic structure located in Downtown Washington, D.C.

The building was built to house a family-run bank that was organized in 1887, and was developed through a real estate investment partnership.

The banking room, which is still in existence, is on the main floor of the building and has rental office spaces above.

The building was designed by prominent Washington architect Jules Henri de Sibour in the Classical Revival style with elements of the Chicago School.

The exterior of the building is faced with ornamented marble and glazed terra cotta with textured spandrels.
