Final answer:
The projection of a roof extending beyond the supporting wall is called eaves (option 1) , serving both aesthetic and practical purposes in various architectural styles.
Step-by-step explanation:
If the roof extends beyond the wall that supports it, the projection is called eaves. This architectural feature is common in many house styles, serving both aesthetic and practical purposes. For example, in early 19th century New England, houses with gable ends facing the street, known as Temple Front Houses, would often have eaves that contributed to their stylish appearance. Similarly, the French were known to integrate eaves into their Creole Cottages, which also featured porches or verandas extending from the eave line to provide shade and coolness.
In addition to providing an architectural decorative element, eaves have the functional advantage of protecting the sides of the building from weather, such as rain and snow. They also help to control the amount of sunlight entering the house, providing shade in summer while allowing sunlight to penetrate and warm the house during winter when the sun is lower on the horizon. Therefore, the correct option among the choices provided is Option 1 - Eaves.
