1. Freehand Sketching of a Bungalow

• Freehand Sketching: This is the ability to draw buildings without the use of instruments like rulers or compasses. It requires understanding proportions, shapes, and perspectives.
• Sketching a Bungalow: A bungalow is a single-story house with a simple design. It usually includes a front porch, roof, walls, windows, and doors.
  • Step-by-Step Sketching Process:
    1. Start by drawing the outline of the building (rectangular or square shape for the bungalow).
    2. Add the roofline and make it sloping or gabled as per the design.
    3. Sketch the walls, doors, and windows in proportion.
    4. Add details like the front porch, if present, and other design elements.
    5. Label all parts of the bungalow with the correct building terms.

2. Identifying Building Parts and Their Terms

• Roof: The top covering of a building, designed to protect from weather.
• Wall: Vertical structures that enclose or divide spaces.
• Door: A movable barrier used for entry and exit.
• Window: An opening in the wall, typically glazed, allowing light and air.
• Foundation: The base of the building, providing support.
• Floor: The lower surface of a room, typically made of concrete, wood, or tiles.
• Porch: A small, covered entrance to a building.
• Elevation: A view of the building from one side, showing height and features.
