European European-style homes borrow materials and exterior details that are common to the French, English, Spanish, and Mediterranean architectural traditions. Typical features of European-style home plans include keystones, quoins, copper-top bays, repeated arches, wrought-iron balconies, clay-tile roofs and decorative window boxes. Exterior cladding is usually stucco, stone or brick. The best-designed European-style home plans are enjoying a resurgence in the United States.
