GSK have recently announced that they are closing their factory in Slough:

This building is well known locally as the Horlicks Building and can be seen by anyone in a train passing along the Great Western Mainline from the west of England into Paddington. Built in 1908, architecturally its most notable features are the large HORLICKS signage that sits above the roof, the castle like tower with it's art-deco clock and particularly from a distance the large circular chimney.
There are concerns by many local residents that the site will be bought up by developers and demolished to be replaced by offices or apartments, rather than retained in its current form.
As a remnant of Slough's early industrial history, it tells an important part of the town's history and is known as a local landmark to everyone living in the town. To lose it would be a great loss to the town.
