Sun Yuan, an interior designer, spent 8 years and 6 million building a home in the old city of Suzhou and named it Qi Yuan. The house has a traditional look, with Chinese-style natural views inside the house. It covers an area of around 350 m2, with a 100-m2 garden. Surprisingly, there's no A/C in the house, but the temperarture and humidity indoors are stable all year around.
