We spoke about the usability and further development of the Chinese roof profile in Chinese buildings today. How did this roof, this remarkable Chinese roof, which gives Chinese architecture a special signature against which other features pale into insignificance, come about? It is a saddle roof with an exaggerated rounding of the ridge and wide out-swinging eaves, and the surface is raised to the highest shine through the intensity of gleaming glazed tiles which display all the colours of nature: light and dark red, lemon yellow and golden yellow, sky blue and peacock blue, rare green and brown glazes of every kind. Through the wave profile of the over- and under-lapping tiles – which all adds to the formal effect – it survives every kind of weather.
