The most attractive place for me in Britain museum is the ceiling. A clear and bright ceiling provides a good natural light inside the building. The transparent material makes the space expanded. The roof covers the whole area of the Great Court spans from the room in central to the edge of the buildings. The structure of the roof is formed by different size of triangular in a curve shape, such as a net full of triangular. This ceiling gives a strong sense of visual space. I thought I could draw the ceiling along the lines, but it wasn’t easy.
