The complex is a brewery, and while brewing has long since ceased here, the fabric of the place retains a quiet coherence: a central yard enclosed by two- and three-storey stone buildings, and a rendered stone chimney built into the southern range, square in plan and measuring 1.75 metres on its north-south face.

The 1843 date stone marks a period when industrial brewing in Ireland was consolidating rapidly, with larger operations replacing the small domestic and tavern-based brewing that had characterised earlier centuries. This complex at Knockbrogan was part of that shift. At some point in the early nineteenth century it was repurposed as a bottling store, suggesting the site moved with the trade rather than against it, adapting its infrastructure as the industry changed around it. The chimney is a useful reminder of the scale of heat and processing that even a regional brewery required. Such chimneys were structural as much as functional, built to draw combustion gases from kilns or boiler houses, and incorporating one into the masonry of a range rather than standing it free reflects the pragmatic density of industrial building of the period. The complex is now in mixed use, its various buildings serving different functions.
