The Buckingham today, a retail outlet for the Body Shop chain.
The right-hand structure was an addition to the original building which allowed it to stretch out over the end of Buckingham Road, possibly because Montague Street become pedestrianised?
It was common practice to have a door on the corner at that time (before the side addition) but here it has been converted into a window. The pediment above still exists, although slightly blunted.
