The construction of a building involves several critical components, each serving an essential role in ensuring the structure’s stability, functionality, and durability. In this article, we’ll break down the fundamental parts of a building, as illustrated in the diagram, and explain their purposes in modern construction.
1. Superstructure and Substructure
The components of any building can be classified into two primary categories: the superstructure and the substructure. The superstructure refers to the part of the building that is above the ground, while the substructure includes the foundational elements below the ground.
2. Foundation and Footing
The foundation is one of the most critical components of a building, as it supports the entire structure. It is located below the ground level and provides stability by distributing the load of the building to the soil beneath. The footing forms the base of the foundation, helping spread the load evenly. Without a strong foundation, the building would lack structural integrity.
3. Plinth Level
The plinth level is the point where the superstructure starts, and it is slightly above ground level. It helps prevent water from entering the structure by acting as a barrier. The plinth protects the building from moisture and serves as a transition between the substructure and the main body of the building.
4. Damp Proof Course (DPC)
The Damp Proof Course (DPC) is a layer of waterproof material applied between the brick wall and the foundation. Its purpose is to prevent moisture from the ground from rising into the walls of the building. This layer is essential in protecting the structure from dampness, which can cause damage to the building materials over time.

5. Walls and Flooring
The walls are the vertical structural elements that define the shape and layout of the building. They provide support for the roof and enclose the interior spaces. Brick walls are commonly used for their strength and durability.
The flooring refers to the surface on which occupants walk, and it plays a vital role in the comfort and usability of a building. It must be strong enough to withstand the loads imposed by people, furniture, and equipment.
6. Doors and Windows
Doors provide access to the interior of the building and allow for the movement of people and goods. Windows are openings in the walls that allow natural light and ventilation into the building. The placement and size of doors and windows are essential for the functionality and aesthetic appeal of the structure.
At the window sill level, the window frame sits slightly raised to protect the window from rainwater and provide structural support.
7. Lintels and watershed
Lintels are horizontal beams placed above doors and windows to support the wall above these openings. They are critical for distributing the load away from these openings and preventing structural damage.
A watershed is a small overhang above windows and doors, which helps protect these openings from rain and weather elements.
8. Roof and Ceiling
The roof is the top covering of the building, designed to protect the interior from weather elements like rain, snow, and sunlight. An R.C.C. roof slab (Reinforced Cement Concrete) is commonly used due to its strength and durability. It forms the main load-bearing structure of the roof.
The ceiling, located beneath the roof slab, provides an interior finish that conceals the structural elements and enhances the aesthetics of the building.
9. Parapet Wall and Coping
A parapet wall is a low wall that extends above the roof, primarily used for safety and aesthetics. It prevents people from falling off the roof and can also act as a barrier against wind and rain.
Coping refers to the protective covering placed on the top of the parapet wall. It shields the wall from rainwater and weather damage, helping to prolong its lifespan.
