The Adam Joseph Lewis Center Annex is a renovated 19th-century home. It houses college offices and lab space for the Environmental Studies Program.
The home was renovated to include environmentally sustainable features such as a composting toilet, energy efficient double-paned windows, and cellulose as a recycled and environmentally friendly insulation. The south-facing porch of the building was turned into a sunroom mainly for horticultural uses.
