Working drawings in interior design refer to the detailed technical drawings that communicate the design intent and provide information for construction and implementation. These drawings are typically created by interior designers and architects and serve as a guide for contractors, builders, and other professionals involved in the construction or renovation process.

1. Floor Plans: These drawings provide a bird’s-eye view of the space, showing the layout of rooms, walls, doors, windows, and other architectural elements. Floor plans also indicate dimensions and may include furniture placement.
2. Elevations: Elevations are drawings that show the vertical surfaces of a room or space. They provide detailed information about the heights of walls, the placement of windows and doors, and any other design features on the walls.
3. Sections: Sections are vertical or horizontal cut-through views of the space that show the relationships between different elements such as walls, ceilings, and floors. Sections help visualize the interior space and provide details on construction methods and materials.
4. Details: Detail drawings zoom in on specific areas or design elements to provide more information on how they should be constructed. This can include intricate designs for built-in cabinets, millwork, lighting fixtures, or other custom features.
5. Electrical and Lighting Plans: These drawings show the location of electrical outlets, switches, lighting fixtures, and other electrical components within the space. They provide guidance to electricians during the installation process.
6. Plumbing Plans: Plumbing plans indicate the location of fixtures such as sinks, toilets, showers, and other plumbing elements. These drawings are crucial for plumbers during the installation or renovation of bathrooms and kitchens.
7. Finish and Material Schedules: These schedules provide a comprehensive list of the finishes and materials to be used in the interior design project. They include specifications for flooring, wall finishes, paint colors, cabinetry, countertops, and more.

Working drawings are typically created using computer-aided design (CAD) software, which allows for precise measurements, easy modifications, and clear communication between the design team and the construction team. These drawings ensure that the design vision is accurately translated into the finished interior space .
