The Emerald Building, which was built in 1941, is a three-story concrete and concrete block commercial building that sits on a pie shaped lot at the intersection of Union mall and Bishop street. It is distinguished by its ship-like appearance which is emphasized by the rounded prow fronting on Bishop and Union mall. The exterior has a flat roofed awning which wraps around the building. The first floor features store-front windows while the second and third story features a band of one-over-one windows. The Emerald Building is architectural significant as an example of moderne style architecture applied to a commercial building in Honolulu. The building was designed by Alfred Preis when he worked for the firm of Dahl and Conrad.
