70 George Street, Oban

70 George Street in Oban is a three-storey, L-plan tenement building dating from around 1840, located at the corner of Stafford Street and George Street. It is designed in a plain classical style, featuring a curved entrance bay at the corner. The ground floor was originally finished with channelled ashlar from the cill level upwards, but much of this has been replaced with plate glass windows or rendered over. The building has smooth render with ashlar details, all painted, and includes a base course. The cornice at the original ground floor window cill level has mostly been removed, while there is a cornice above the ground floor and first floor cill course, along with a cornice with a blocking course. The first-floor windows are architraved and corniced, while the second-floor windows are architraved and lugged at the cill. Pilasters extend the full height of the building and are channelled at the ground floor.

On the west elevation facing George Street, there are two bays with regular fenestration and a curved corner bay to the right. The ground floor features modern plate glass windows and smooth render, replacing the earlier channelling and voussoirs of the original windows. The south elevation facing Stafford Street has three bays and a curved corner bay to the left. Here, two plate glass windows and smooth render have replaced the earlier fenestration at ground floor level, while the upper floors maintain regular fenestration with windows in the left bay. A chimney above has been removed.

The building features timber plate glass windows on the first and second floors and has a grey slate roof that is hipped at the corner. A 12-flue, corniced stack is located on the north gable, which is smooth rendered and painted, while there is a single flue stack on the east gable.
