The upper floors have recessed sash windows beneath flat gauged arches. A plat band finishes the ground floor stuccowork, while No. 56 has a stone-coped parapet. No. 54 is adorned with a stucco string course over the third floor, and both houses have original cast iron balconies with geometric patterns on the first floor, as well as cast iron area railings topped with urn finials.
