What does architectural decoration and interior design encompass?

　　1. Demolition and Renovation Project

　　The first step in renovation typically involves structural modifications and demolitions based on the new functional layout. This includes removing old walls, floors, ceilings, doors, windows, and other elements that no longer meet the requirements of the new design. At the same time, new partition walls are constructed, door openings are adjusted, and spaces are reorganized. During this phase, it’s crucial to avoid arbitrarily demolishing load-bearing structures; instead, all work must comply with building safety regulations to ensure that the renovation does not compromise the overall structural stability of the building.

　　2. Water and Electricity Pipeline Installation Project

　　Hydropower engineering is the hidden core of home renovation, directly affecting the safety and convenience of later use. It includes the installation of water supply pipelines, the setup of drainage systems, the routing of both strong and weak current wiring (such as lighting, outlets, network cables, and TV signals), and the configuration of distribution boxes. Construction must strictly follow the design drawings; all stages—such as threading wires through conduits, conducting pressure tests on water pipes, and performing waterproofing treatments—must meet the required standards to prevent potential hazards like leaks and short circuits in the future.

　　3. Masonry and Flooring Works

　　This section covers the preparation of wall and floor substrates as well as finishing work. It includes wall plastering, leveling, and tile installation (in areas such as kitchens, bathrooms, balconies, etc.), as well as floor leveling, waterproofing layer construction, and the laying of floor tiles or flooring materials. In wet areas such as bathrooms and kitchens, waterproofing must be thoroughly executed and a water-closure test conducted to ensure there are no leaks. The flatness of the floor directly affects the quality of subsequent flooring installation.

　　4. Woodwork and Ceiling Works

　　Carpentry work primarily includes the fabrication of ceilings, the creation of decorative background walls, on-site production of custom cabinetry, installation of door and window frames, and laying of wooden flooring. Ceilings are often used to conceal pipelines, delineate spaces, or visually enhance ceiling height; materials commonly employed include gypsum boards, aluminum panels, and wood panels. When performing on-site carpentry, it’s crucial to pay attention to moisture-proofing and fire-retardant treatments to ensure structural stability and aesthetically pleasing joints.

　　5. Painting and Wall Decoration Works

　　Wall decoration is an essential element in enhancing the aesthetic appeal of a space. It involves applying putty to walls, sanding them, and then painting with latex paint, or alternatively, installing wallpaper, wall fabrics, wainscoting, or artistic coatings. The construction process requires a smooth, crack-free substrate, even application of paint, and consistent color tones. Different materials are suitable for different spaces—for example, latex paint is ideal for bedrooms and living rooms, while waterproof coatings are recommended for kitchens and bathrooms.

　　6. Installation Engineering

　　In the later stages of renovation, a large number of equipment and accessories need to be installed, including lighting fixtures, switch and socket panels, bathroom fixtures (toilets, sinks, shower enclosures), kitchen cabinets, range hoods, gas stoves, doors and windows, and hardware components (door locks, hinges, handles, etc.). Installation must precisely align with the positions pre-reserved during earlier stages to ensure proper functionality and smooth operation.

　　7. Interior fittings and soft furnishings arrangement

　　After the hard decoration is completed, soft furnishings enhance the overall ambiance of the space. This includes the arrangement and placement of curtains, carpets, decorative paintings, greenery, furniture, and home appliances. Soft-furnishing design should be harmonious with the overall style, paying close attention to color coordination, material consistency, and spatial proportions to create a comfortable and livable living environment.

　　8. Cleaning and Completion Acceptance

　　During the final stage of the project, a comprehensive cleaning must be carried out to remove construction debris and dust. Following this, a completion acceptance inspection will be conducted to verify that all works meet the design requirements and quality standards. This includes testing whether the electrical and plumbing systems are functioning properly, checking whether doors and windows open and close smoothly, and inspecting walls and floors for hollow spots or cracks. Once the acceptance inspection is passed, the project will be handed over for use, and warranty services will be provided.
