The midcentury modern look of Claridge House is a curtain wall exterior that was done, most likely in the 50s, to a much older building. Emporis gives its original completion date as 1906.

If you venture into the alley you can see the bricked in tall arched windows of the first floor. The building, then as now, had shops on the first floor; but the building's lobby was on Clifford before the renovation that transformed it into the current Claridge House Apartments.
