The L-shape in architecture refers to a design layout that forms a right angle, resembling the letter "L." This configuration is often used in residential and commercial buildings to create distinct functional areas, such as separating living spaces from service areas. The L-shape can enhance natural light and ventilation by allowing windows on two sides of a room. Additionally, L-shaped designs can optimize land use, making them popular in urban settings where space is limited. This layout can also provide outdoor areas, such as patios or gardens, that are easily accessible from the main living spaces, promoting a seamless indoor-outdoor connection.
