Building design refers to the process of creating plans and specifications for constructing a building. It involves considering various factors such as functionality, aesthetics, safety, and sustainability. Architects and designers work together to ensure that the structure meets the needs of its users while adhering to local regulations and codes. The design process typically includes conceptual sketches, detailed drawings, and 3D models. Tools like CAD software help visualize the project and make necessary adjustments. Additionally, building design often incorporates elements like landscaping and interior design to create a cohesive and appealing environment.
