7.4. Exercise: 7.2

Draw plan, elevation and sectional elevation including electrical, plumbing and sanitary services for a given line diagram of two storey residential building.

In this exercise, you will create important building plans that provide a comprehensive view of a proposed two-storey residential building. This involves drawing different views, including a plan view (the layout as seen from above), elevations (views of the building's sides), and sectional elevations (views that show a slice of the building to display internal features). You also need to incorporate essential services such as electrical wiring, plumbing, and sanitary systems into your drawings.

Imagine you are a movie director planning a film set. Just as you would sketch out the different scenes and their elements (like props, lighting, and camera angles), in building designs, you sketch out different perspectives and systems for clarity and functionality.

The plan provides a bird's eye view of the layout of the rooms, walls, and utility placements.

The plan view is crucial as it shows how the space will be used and how different rooms are connected. It includes the placement of walls, doors, and windows, along with key features like kitchen counters, bathrooms, and furniture layouts. This layout helps visualize how movement will flow through the house.

Think of planning a party in a large hall. You need to decide where to place tables, the buffet, and the dance floor so that guests can move easily. Similarly, the plan view ensures that all rooms and areas in the house are functionally placed.

Elevations provide vertical aspects of the building, showcasing height and exterior finishes.

An elevation drawing is essentially a visual representation of one side of the building. It includes details such as the height of the building, types of windows and doors, and finishing materials like brick or paint. Elevations help understand how the building will look from the street and how it fits within the surrounding environment.

Consider how an architect showcases their latest design. They provide pictures of the building from different angles to potential buyers, giving a beautiful impression of its height and style. Elevations serve that very purpose in building planning.

Sectional elevations illustrate the internal features and structural elements of the building.

A sectional elevation is like a cut-through view of a building, revealing how spaces are structured internally. This drawing helps illustrate room heights, the arrangement of floors, staircases, and the placement of utilities like plumbing pipes and electrical systems. It is crucial for ensuring that all elements of the building integrate well and function effectively.

Imagine slicing a loaf of bread to see the inside textures and layers. Similarly, a sectional elevation allows you to 'slice' through the building design, enabling you to examine how different floors and internal systems are organized.

Including electrical, plumbing, and sanitary services in your drawings is vital for functionality.

When designing a building, it is crucial to include plans for electrical wiring, plumbing (water supply and drainage), and sanitary systems (toilets and waste management). These systems must be carefully planned to ensure they are efficient and meet safety standards. Proper incorporation in the drawings means that the eventual construction will adhere to local building codes and will function as intended.

Think about the intricate wiring and piping in a smartphone. Just like how these systems work together to provide seamless connectivity and user experience, the utilities in a home need to be thoughtfully integrated to ensure comfort and safety.
