(2) General Layout Design 1, in the overall layout, make full use of and respect the terrain conditions, the relatively large main body of the Museum of Art will be arranged along the South Ridge Road, and the river side of the 2# building ground only one floor, combined with the site, will be the two main body of the ring
And place, between the formation of a pleasant scale of the inner garden, the building itself becomes the inner environment. The whole layout is high in the east and low in the west, which is like a jagged and strange rock placed by the natural river in the west.
2, space form design:
Art museum by its own personality qualities, the need for creative spirit of the times, in the design of the use of the more daring compositionist ideas, in addition to the plane on the free stretch, in the three-dimensional space on the use of large-scale space free undulating interspersed with the shape of the building from the inside to the outside are formed in a kind of free and passionate architectural three-dimensional space, the Museum of Art is not only a place to display the artistic The art gallery is not only a place for displaying art, but also a work of art in itself, which is inspired by the association of a pile of rubble in the natural state.

3, the choice of building materials Combined with the idea of this design, in order to create a more powerful and expressive effect on the shape of the main body, the exterior is mainly wrapped in metal zinc plate and combined with internal materials and peripheral decorations, to open the reflective glass window with a sense of rhythm to enliven the texture of the facade.
The use of natural stone in the volume areas close to the ground level of the main contour sets off the building's heaviness, and a large-span all-glass curtain wall system is used for the transitional volumes between the interlocking buildings and the light atrium.
4. Traffic organization In order to avoid direct conflict with Lingnan Road, the main entrance is set in the inner courtyard, entering on foot from the south side, and motor vehicles are parked on the south side of the periphery of the building, and the main body has a height difference of nearly 4m, and the main body of the building is surrounded by the inner courtyard space will be independent and free from motor vehicle interference to achieve a strict separation of pedestrian and vehicular traffic organization, and to the art gallery required by the quiet seepage of the environmental quality to create conditions. The quality of the environment required by the art gallery has created the conditions.
