Colonial homes are symmetrical, where each side is a mirror image of the other. Decorative elements are restrained and drawn from Greek and Roman classical architecture. The entry is generally very obvious with a large door, transom, sidelights, hood, or even a portico.
Other design fundamentals may include classical columns, two-story pilasters, quoins at corners, dentil trim under eaves, or Palladian windows. The entrance is centered and accented with columns, pilasters, pediment, and may be hooded to create a covered porch. Symmetrical windows may have crossheads and wide trim and/or shutters.
