Thornhill Branch Opens in February 2019

The new and improved Thornhill Branch will open on Wednesday, February 13, 2019 at 9:00 a.m. as part of the Your Library Renewed campaign. Construction on the Thornhill Branch began in early 2018. The new building replaces a library branch which opened on the site in 1976.

See photos of the construction process.

The new Thornhill Branch is approximately 20,000 square feet in size and features a colorful interior, with abundant natural light and comfortable seating. Architectural light fixtures, new windows and updated furniture give the space a modern and welcoming feel.

The new children’s area is brightly decorated in shades of blue, orange and magenta and includes kid-friendly furniture, interactive learning stations, reading nooks and porthole windows that look out into the branch. Kids will also have access to an outdoor activity area, that will open in the spring, featuring seating for story time, art easels, a small play structure and oversized musical instruments. The outdoor area is sponsored by the St. Louis County Library Foundation.

The teen space features shades of orange and blue, along with fun furniture and computers. The renovated branch includes a computer lab, where patrons can take free classes on a variety of technology related topics. Other highlights include two updated community meeting rooms, a business center with fax, copy and scanning machines; a commons area with tables, a laptop bar and vending machines; a quiet reading area; and three private study rooms.

The new Thornhill Branch was designed by Mackey Mitchell and Bond Architects. The project’s budget was $5.4 million and was funded by proceeds from a 2012 tax initiative.

The Thornhill Branch is the 16th location to be renovated or replaced as part of the Your Library Renewed campaign. Construction is currently underway at two other locations: Mid-County and Meramec Valley. These branches are expected to reopen in 2019. The timeline is subject to change based on weather conditions and other factors. Visit for more details.
