The building was designed by William H. Weeks in the Greek Revival style and is included on the National Register of Historic Places.

The election passed easily, supported by the San Francisco Chronicle and the Livermore Valley Improvement Association.

The original structure, which was built in the Classical Revival architectural style, still stands and now houses the Livermore Heritage Guild's History Center and Museum.

Several Livermore residents and local farmers furnished volunteer labor to assist the construction effort.

[c] There are light colored quoins at the corners, projections and foundation that provide contrast with the yellow walls.

[4] A central portico, decorated with a pediment that is supported by two pairs of Greek Ionic columns, frames the main entrance (on the Third Street side).

The largest was called the Reference Room, which contained shelves of books, chairs and tables, and covered the east side of the building.

[4] The interior of the building has been maintained as it was built, except for modernization of plumbing, addition of emergency exit doors, installation of an exterior elevator and a concrete ramp.

The 60-foot (18 m) tall flagpole that was formerly at the intersection of Livermore Avenue and First Street was relocated to Carnegie Park and erected beside the plaque.

The east and west ends of the park contain picnic tables that were installed late in the 20th century.

[10] The building and its surrounding park were added to the National Register of Historic Places in 2011, with reference number 11000876.
