A G+2 house model typically consists of three floors, with the ground floor serving as the entrance and main living area, the second floor serving as additional living space and bedrooms, and the third floor serving as a rooftop or terrace area.

The exterior of the house can be designed with a variety of materials such as bricks, concrete, or wood, and can include features such as balconies, windows, and decorative elements. The roof can be designed as a flat or sloped surface, with the possibility of adding solar panels or a rooftop garden.

The interior of the house can be designed with an open floor plan, with the ground floor typically including a living room, dining area, and kitchen. The second floor can include bedrooms, bathrooms, and additional living space, while the third floor can be designed as an outdoor lounge area or garden space.

In terms of the rendering, a 3D model can be created to showcase the design of the house. This can include detailed textures and materials to accurately depict the appearance of the house, as well as lighting and shadow effects to create a realistic and immersive experience. Additionally, the model can include furniture and decor to give an idea of how the house could be decorated and lived in. Overall, a G+2 house model with rendering can provide a clear and realistic representation of the design and layout of the house.
