As well as embracing the Colonial Eclectic style, Nam Koo Terrace also adopts Classical Revival and Italian Renaissance architectural features combined with traditional Chinese decorations and motifs. The red bricked outer wall of the building is considered to be one of the major features of its architectural construction. Besides the red brickwork; rusticated quoins, moulded cornices, and voussoired arches over the windows add to the uniqueness of the structure's architecture.
