Wei Residence in Anping Haitoushe (安平海頭社魏宅) is the ancestral home of the Qing Dynasty Vice-Admiral Wei Da-you. It has a single-wing layout, common amongst the houses of the lanes and alleys of Anping. It is built from bricks, with oyster cement spread on the walls and a “horseback” style roof ridge. The main room has a traditional layout, on the left side there is small archway connecting to the outside, with bedrooms on the East side. The layout of the house is typical of Anping houses of its time. The “single wing” design has made an appearance in the design of new homes today. This old house should not be missed when exploring the lanes and alleys of Anping.
