Space design refers to the secondary display and arrangement of rooms, as well as fabrics, paintings, plants, etc. by using ornaments and furniture that are easy to replace and change their positions, such as curtains, sofa cover, cushions, craft table cloths and decorative handicrafts, decorative wrought iron, etc. As a movable decoration, home decoration can better reflect the owner's taste and is the crowning touch to create a home atmosphere. It breaks the traditional boundary of decoration industry and recombines handicrafts, textiles, collectibles, lamps, flowers and plants to form a brand-new concept. The concept of space design is not limited to the above understanding. The above description refers to the concept and connotation of decoration, which belongs to the design category of soft clothes. Space design includes office space design, home interior decoration and cultural leisure space design (museums, exhibition halls, schools and libraries, bars, hotels, etc.). ), commercial space design (shopping malls, specialty stores, counters, etc.). ), and the specific design projects include spatial structure planning, hydropower design, lighting design, decoration, soft decoration (sofa cover, curtains, ornaments, paintings, lamps, flowers, etc. ), etc. Therefore, space design can be regarded as a smaller concept than architectural design. Architectural design pays attention to external design (including structure, of course), while space design pays attention to internal design.
