Ju'er Hutong is located in the east of the north end of Nanluogu Alley. In 1990, the renovation project of dilapidated buildings on Ju'er Hutong presided by Wu Liangyong, a famous Chinese architect, organically renewed the small hutong in the ancient lane, making it not only retain the charm of the antique Siheyuan but also serve as the modern residence. In 1992, it was awarded the "ARCASIA Gold Medal" by the Architects Regional Council Asia and the "World Habitat Award" in 1993.

In the middle of the Hutong, there are small courtyards gathered by 2-storey and 3-storey buildings with black tiles and white walls in the north, which are not only as beautiful as Jiangnan dwelling houses, but also as charming as the traditional Siheyuan. In addition, they also share harmonious styles with their surroundings. This is the altered Siheyuan in Ju'er Hutong. According to the urban planning theory of "organic renewal", Professor Wu Liangyong believes that in the transformation of ancient cities, good and historic buildings should be preserved, shabby but still usable ones should be repaired, and seriously dilapidated ones should be demolished. The gradual transition process not only keeps the continuity of history but also forms an organic overall environment.

Featured by the privacy of unit apartments and the neighborhood of traditional residence, the new Siheyuan organically integrates with the old hutong patterns and preserves the style and features of the ancient capital, which is a successful exploration for the transformation of the old city. At the east entrance of Ju'er Hutong, No. 3, No. 5 and No. 7 courtyards and No. 6 Shoubi Hutong was the residence of Ronglu, the Governor-General of Zhili and the Minister of the Board of War in the Qing Dynasty. It used to be a large mansion with three parts: a western-style building in the west, a Chinese-style Siheyuan with five entries in the east and a garden in the middle. After liberation, some were used to be the Embassy of Afghanistan, and later they were divided into several parts as the dormitory. With a damaged structure, it is subject to poor protection.
