Element: A symmetrical front facade. Traditionally Cape Cod homes have a symmetrical appearance and layout inside with a center hall and equal space on either side. Colonial Cape Cods featured a central chimney linked to a fireplace in every room; 20th century versions like the one shown moved the chimney to one end of the home. How to make it your own: Pairs of planters and sconces on either side of entries can create the appearance of symmetry even when the fundamental layout is asymmetrical.
