At the request of Party A, remodeled a 37 m2 old house in a Hutong of Beijing. The original dwelling, with a 2.7 m clear height and only one bedroom, turned into a full-featured staff residence with two independent bedrooms. The house is located on the first floor of a two-story building lining the North Xinhua Street. Though with an exclusive entrance, the house's lighting and ventilation were less than ideal. An open shaft in the rear part of the house cut into the access to the bathroom, a total inconvenience especially on rainy days.
