A 2D house plan is a technical drawing that represents the layout and design of a house in two dimensions (length and width). It typically shows the placement of rooms, doors, windows, and other architectural features, and provides an overview of the overall floor plan.

2D house plans are commonly used by architects, builders, and contractors to visualize and plan the construction of a house. They are also used by real estate agents and homeowners to market and sell a property.

A 2D house plan typically includes the following features:

• Floor plan: A top-down view of the layout of the house, including the placement of rooms, doors, and windows.
• Room dimensions: The size and shape of each room, including ceiling height.
• Electrical and plumbing symbols: Representations of electrical outlets, light fixtures, and plumbing fixtures.
• Furniture layout: An optional feature that shows the placement of furniture in each room.

In a 2D house plan, the view is limited to the outline of the structure and its features. However, it provides a clear and simple representation of the house's layout and design, and is an essential tool for planning and construction.
