European House Plans: European house plans borrow materials and exterior details that are common in French house plans, English house plans, Spanish house plans, and Mediterranean house plans. Typical features of European house plans include keystones, corner quoins, and copper-topped bay roofs, which punctuate the home’s traditional massing. Exterior cladding is usually stucco, stone or brick. European house plans are enjoying a resurgence in the United States, and our gorgeous collection has some of the best.
