The building was erected in 1909, to make tablet sugar, syrup and other products. Renovated as a three-storey office block, the building retains many original features, such as the load-bearing window frames, the open plan layout made possible by cast iron beams, the loading dock opening to Refinery Square and the lift well (now glazed) which cuts a vertical shaft through the building.

According to Wikipedia,

Tablet is a medium-hard, sugary confection from Scotland…. not as soft as fudge, but not as hard as hard candy [and] often flavoured with vanilla, whisky, or nuts.
According to The Scots Kitchen by F. Marian McNeill, tablet is first noted … in the early 18th century… Tablet is also mentioned in Oor Wullie, a comic book focusing on a scruffy Scottish boy in a world where people speak an extreme form of Scots English.

(Scots had the worst – and fewest – teeth in Western Europe.)

The CSR venture was initiated by a Mr Turner in 1908:

The making of tablet sugar is a matter which we must look into and provide for in the very near future in a way and on a scale which we have not hitherto done; what I saw in England convinced me of the possibilities of the business, and it is sure to extend here at a greater rate than the past developments would lead us to expect; so that our present appliances… will be found altogether inadequate unless we … look ahead a bit.
