The ground floor of the house features an open courtyard that leads into the reception hall through a highly ornamented fence door (pintu pagar). Beyond the reception hall is an ancestral hall and kitchen. The former would have been the primary living space, with daily activities undertaken in the larger end of the room where an airwell is incorporated. On the second floor of the house are a master bedroom and a rear bedroom, constituting the private spaces of the house.
The ancestral hall
The third floor of NUS Baba House was added to the original dwelling around 1910 as an additional bedroom. As part of the restoration process this space was converted into a gallery for exhibitions and projects that foster contemporary engagements with traditional Peranakan culture, serving as a conducive space for questioning and speculation.
The gallery
With the intention to present the house as a typifying example of a Peranakan home in the 20th century, furniture from the Wee family, as well as portraits and household objects are displayed in their original context. Further items have also been donated and sourced to recreate and examine the material histories of Straits Chinese communities. This collection of artefacts is known as the Straits Chinese Collection.
