Eyebrows are architectural elements designed to provide shade and protection from direct sunlight. They are typically horizontal projections extending from the building's facade above windows or doors. Eyebrows can be made from various materials such as wood, metal, or concrete, and they come in different shapes and sizes depending on the design intent and climate considerations. Besides their functional role in shading, eyebrows also contribute to the visual appeal of a building by adding depth and dimension to its facade.

Louvres are slatted structures installed in windows, doors, or walls to control the amount of light, ventilation, and privacy in a building. They consist of overlapping horizontal or vertical slats angled to allow airflow while blocking direct sunlight and maintaining privacy. Louvres can be fixed or adjustable, with adjustable louvres providing occupants with greater control over ventilation and light levels. In addition to their functional benefits, louvres can enhance the architectural aesthetics of a residential building, adding texture and visual interest to its exterior.
