I sometimes hear: "What is the difference between Mediterranean and Spanish Revival style?"
Well, the first thing that really jumps out to me the amount of space between the roof line and windows. In a normal Mediterranean style home, the windows will be very close to the roofline.
I have seen it often in my native South of France where a lot of "bergerie", farms for goats and sheeps, typically built in a rectangular fashion, has little space between the windows and the tiled roof. It makes for a cozy and inviting feel.
What we call Spanish Revival is actually a local style in Southern California and reaches as far out as Texas and in some cases, further East. It is a mixture of Spanish Andalusian typical homes but happily marries Mediterranean, Italian Renaissance and Moorish styles.
