The basic speciality of the style is that it effortlessly and beautifully blends form and function with materials and features that keep interiors cooler in warmer climates, usually using techniques of passive cooling – such as a central courtyard, paved or landscaped and often with a fountain or courtyard. Common exterior elements typically include numerous oversized windows, carved entry doors, multiple balconies, high arches, columns, arcades and ornamental wrought iron work on gates and windows.
