Yuen's Mansion, Grade II historic mansion in Mui Wo, Hong Kong.

Yuen's Mansion, also called Yu Tak Lei Wai, is a walled farmstead in Chung Hau, Mui Wo, on Lantau Island, built between the 1920s and 1940s. Its six graded structures are the main house, front house, granary, East and West watchtowers and a small house next to the East tower. The buildings are deliberately offset at angles rather than aligned, creating hidden corners and blocked sightlines.

The Yuen family had the property built in the early 1900s, when Mui Wo was still a farming community on a largely rural island. Over time, as the family's presence in the area faded, the building was eventually listed for its historic value.

The name Yuen's Mansion, or Yu Tak Lei Wai, refers to the family of builder Yuen Wah-chiu, a former member of the Chinese Nationalist Party. The compound is counted among Mui Wo's four watchtowers, together with the Luk Tei Tong tower and the collapsed one on Butterfly Hill. Part of the house is now abandoned, while another part serves as a dormitory for workers of nearby holiday flats.

The property is private and generally closed to outsiders; it belongs to the third-generation heir of the Yuen family. From Mui Wo Bus Terminus it is about a 20-minute walk, or take bus 3M to Ngan Wan Estate and walk 5–7 minutes. The site is in Chung Hau Tsuen, near the Chung Hau bridge.

The buildings are deliberately offset from one another rather than aligned, creating hidden corners and blocked sightlines. A 2005 HKU thesis by Lee Chung-ming compares this defensive layout to a medieval fortified complex. A cannon still stands at the site.
