Built for Sime Sanderson and Co., Botany Mill is a rare survival of a 'slow loom' mill in Galashiels, and is, along with the other remnants of the industrial past in the town, an important reminder of the origins and expansion of the town in the later 19th century. The mill is a prominent feature in the townscape and forms part of a significant group of buildings. It is thought that Botany mill is so called as it was the first mill in Galashiels to use Botany Wool. The first mill building in this location was a fulling mill built in 1797 and extended with a spinning mill in 1829 (both demolished). However, a fire in 1870 most likely destroyed that building. The present building probably dates to circa 1870-1880. Multi-storey weaving mills were superseded when fast looms were brought in from about 1880. It is marked as a wood store when sold in 1932.

The importance of the wool manufacturing trade to Galashiels cannot be overestimated, as this industry was the sole reason for its expansion and prosperity in the 19th century. Wool manufacture has largely subsided, but the remaining buildings are important monuments to the industry. (Historic Environment Scotland List Entry)
