An attic is a space located directly under the roof of a building, typically used for storage. It is often accessed by a ladder or staircase and may have limited headroom, depending on the roof's shape. Attics can be used to store seasonal items, old furniture, or personal belongings that are not frequently used. In some cases, attics are converted into living spaces, such as additional bedrooms or home offices, once they are properly insulated and renovated. The design and use of an attic largely depend on its size and the building's layout.

A balcony is a small, raised platform attached to the outside of a building, typically on an upper floor. It is usually enclosed by railings or walls for safety and is accessed through a door or window. Balconies provide an outdoor space for relaxing, enjoying the view, or placing small items like plants or chairs. They are common in apartments, houses, and hotels and offer a private outdoor area without requiring ground-level space. Balconies can add both function and aesthetic appeal to a building.

A cellar is a room or space located below ground level in a building, often used for storage. It is typically found beneath homes, where it serves as a place to store food, wine, or other items that require cool or dry conditions. Cellars can also be used for additional living space, such as a laundry room or recreation area. They are usually accessed by a staircase or trapdoor and may have small windows or ventilation for air circulation.

A front door is the main entrance to a building, typically located at the front of a home or commercial property. It serves as the primary access point for residents and visitors, often designed to be both functional and aesthetically pleasing. Front doors can be made from various materials, including wood, fiberglass, or steel, and are available in a wide range of styles, colors, and finishes to complement the overall architecture of the building. In addition to providing security and privacy, a well-designed front door can enhance the outside appearance of a property and make a positive first impression.

A garage is a building or space, typically attached to or located near a house, used for storing vehicles, tools, or other items. It often has a door that can be opened to allow cars to enter or exit. Garages can vary in size, from small single-car spaces to larger ones that can fit multiple vehicles or serve as additional storage areas. Some garages are used for purposes like workshops or home maintenance tasks, while others are primarily for parking vehicles.

A skylight is a window installed in a roof or ceiling that allows natural light to enter a room from above. It is designed to bring sunlight into spaces that may not have access to traditional windows, making areas feel brighter and more open. Skylights can come in various shapes and sizes, including fixed or operable options that can be opened for ventilation. They are often used in homes, offices, and other buildings to enhance the ambiance and energy efficiency of a space. Additionally, skylights can provide beautiful views of the sky and surroundings, contributing to the overall design of the interior.

A stair is a series of steps designed to connect two levels within a building, allowing individuals to move from one floor to another. Typically enclosed within the structure, stairs consist of horizontal surfaces called treads for stepping on and vertical sections known as risers that support the treads. They can vary in design, including straight, curved, or spiral configurations, depending on the layout and space available. Stairs are essential for accessibility and can be constructed from a range of materials, such as wood, metal, or concrete, providing both functionality and aesthetic appeal in the interior design of a building.
