The Yountville Town Center consists of a new 10,000 sf facility, renovation of an existing Community Hall and a Sheriff's Substation addition to the adjacent Post Office. These three civic buildings frame a new Yountville Town Square.

The new building houses a branch library, multi-purpose room, teen center, meeting and program spaces. Because sustainability was a priority of Yountville's leadershp, a number of green features were integrated: a ground source heating and cooling system, a 38 kw photovoltaic array, low-flow plumbing fixtures, environmentally preferred building materials, efficient lighting and daylighting, natural ventilation, water-conserving landscape, and an innovative subsurface irrigation system.
