The Forest and Annex is a historic apartment building at 901-905 Forest Avenue in Evanston, Illinois. Owner Alfred B. Andrews built The Forest in 1909 and added the annex to the original building in 1912. Andrews would later author Evanston's early zoning ordinances, and he planned his building accordingly, with a spacious lawn providing plenty of room between it and the street. The building has a Prairie School design with a horizontal emphasis, patterned brick, and wide eaves. The 11 apartments in the building all included features such as wood paneling and flooring, fireplaces, and rooms for housekeepers.
